ad29cd6 FIX: hammered out one big bug 16 December 2013, 15:08:46 UTC
40420b6 ENH: made call signature of polar2latlonalt_n similar to that of polar2latlonalt 16 December 2013, 15:07:54 UTC
c752228 FIX: moved conversion of angles from degrees to radians, so that behavior is more intuitive (working with degrees on the user side, and thus actually following the documentation). 16 December 2013, 13:47:02 UTC
da9a659 ENH: Introduced polar2latlonalt_n and helper functions. calculates geographical (sphere based) coordinates from radar coordinates, taking both earth's curvature and the refraction of radar beams in the air into account. 13 December 2013, 15:02:41 UTC
36cf3a1 FIX: added conversion to 32-bit int for RX-data, because otherwise the data type of the array would not be sufficient to store -9999 nodata values. 09 December 2013, 08:04:15 UTC
a5a050e DOC: minor fixes 09 December 2013, 08:02:09 UTC
b504b44 FIX: Fixed wrong datetime interpretation in RADOLAN composite and added new 150 km radius. 06 December 2013, 16:59:49 UTC
4801304 MIN: Trying to make MFB adjustment more robust. Before an adjusment facator is computed, we fit a linear regression and evaluate slope, p-value and correlation. We compute an adjustment factor only if a strong relationship is indicated (slope > 0.1, r > 0.5, p < 0.01). These thresholds might later be made available as function arguments. 18 November 2013, 15:59:53 UTC
a9781f7 MIN: removed the range_lim argument from read_EDGE_netcdf. Limiting the range is something tpo be done outsode the reading function. Now, the entire range is returned. 18 November 2013, 15:57:26 UTC
e094a2e MIN: Introducing exception handling for reading input files in read_EDGE_netcdf. The aim is to at least close files if an error occus during reading, using try except finally. This might be a model for all input functions. The exception will be raised (or can be caught outside the function), but the file will be closed if it was successfully opened. 12 November 2013, 14:43:29 UTC
9844826 FIX: Passing range length to sub-functions within process_raw_phidp2. 12 November 2013, 10:28:57 UTC
d1cc60d ENH: Added new functions for PhiDP reconstruction based on Vulpiani (2012). The functions involve unfold_phidp_2 and a new convenience function process_raw_phidp2. Once we know more about the behaviour of these function, it will be time to clean up the dp module a little. 07 November 2013, 15:42:25 UTC
74d7979 FIX: adding dr to argument list of kdp_from_phidp. 07 November 2013, 14:30:38 UTC
0ff9297 ENH: Added fourth experimental Kdp retrieval based on convolution filter suggested by Kai Mühlbauer. The function is named kdp_from_phidp4. It also takes care of remaining NaN values. If phidp does not contain NaNs, only the convolution filter is applied. 07 November 2013, 12:48:15 UTC
989640f FIX: Fixing bug in handling the end of the beam in kdp_from_phidp2. Also inserted the explicit handling of start and end of the beam to kdp_from_phidp3. 07 November 2013, 10:12:41 UTC
d123bd8 FIX: Accounting for forward/backward propagation effects in kdp_from_phidp2 and kdp_from_phidp3. 07 November 2013, 09:33:27 UTC
b408ddb ENH: New experimental Kdp retrieval function kdp_from_phidp3. This function should be robust AND fast. For contiguous valid regions, it applies a sobel filter, for remaining NaN regions with valid neighbours it performs a local linear regression. Beyond, all the kdp_from_phidp functions now have an argument dr which specifies the gate length (in km). 07 November 2013, 08:58:52 UTC
980a7c9 MIN: kdp_from_phidp2 now explicitely handles the start and the end of each beam. For the start and the end of the beam, we do not use a "central window" around a gate, but we use a forward window for the first L/2 gates and a backward window for the last L/2 gates. 06 November 2013, 08:43:04 UTC
e3a9fca ENH: Adding new experimental function for Kdp retrieval (kdp_from_phidp2). This function uses a moving window linear regression and should also work for data with gaps. STATUS is experimental. 05 November 2013, 08:50:37 UTC
f2ff0ab FIX: Adapting VPR functions to new z-y-x order of 3-D arrays 05 November 2013, 08:48:16 UTC
dcdbbc8 Added correctAttenuationConstrained2 as an attenuation correction very close to Kraemer algorithm. 29 October 2013, 16:33:38 UTC
625072d Added correctAttenuationConstrained2 as an attenuation correction very close to Kraemer algorithm. 29 October 2013, 16:30:46 UTC
0be1ba4 ENH: Added percent bias (pbias) as verificaiton measure to ErrorMetrics. 25 October 2013, 14:17:25 UTC
1520e02 MIN: Provides the option to pass parameters accepted by the functions to process_raw_phidp. This change was necessary so the user is not forced to use the default parameters of all the functions that are used in the convenience funciton process_raw_phidp. 25 October 2013, 13:39:34 UTC
6e27419 MIN: Changing the default value of the margin argument of fill_phidp to 3. 25 October 2013, 13:29:40 UTC
6c04945 MIN: Added the requirement to MFB that there should be at least "mingage" number of valid raw and obs pairs. Also added a try/except statement to the linear regression in case line fitting fails. 25 October 2013, 13:06:05 UTC
4ad7c01 DOC: Exposing the class adjust.GageOnly in the documentation. 25 October 2013, 11:57:29 UTC
c7b1d09 ENH: Making Mean Field Bias Adjustment (MFB) more robust by using linear regression. If biasby argument to MFB.__call__ was "mean", the bias was computed by simply computing the mean of the ratios between obs and est. Now a new argument value is introduced which is "linregr" (now the default value). In that case, the bias is computed from the inverse slope of a linear regression forced through (0,0). 25 October 2013, 11:32:23 UTC
3ad6a90 DOC: Corrected typos with respect to freqencies of typical radar bandwidths. 22 October 2013, 11:30:41 UTC
e2f6e5f MIN: Changes on linear_despeckle and fill_phidp. For linear_despeckle, the first gate is set to nan if the second is nan. For fill_phidp, the computation has been made more robust for the margins of the arrays. 21 October 2013, 09:31:22 UTC
05d08bf FIX: Made sure that the setup_distribute module is packaged for PyPI. 17 October 2013, 13:20:39 UTC
84ef25e MIN: Using the median instead of the mean to compute the value at the margins surronding a NaN region in function fill_phidp. This way, local jumps in PhiDP do not affect the local fill value too much. 16 October 2013, 14:33:15 UTC
b0e8b5b MIN: Removing some redundant ines from fill_phidp. 16 October 2013, 11:16:14 UTC
76e80eb ENH: Changed the way PhiDP values are filled in function fill_phidp in order to avoid Kdp artefacts. Citing from the new function docstring: Contiguous NaN regions are filled by the average of the values of the margins that surround the NaN region. At the left and right margins of the array, these averages are extrapolated to the end. Using the average over the margins takes into account noisy PhiDP. As a consequence, a contiguous region of missing PhiDP will be filled by constant values determined by the edges of that region. Thus, the derivative (i. e. Kdp) in that region will be zero. This bahaviour is more desirable than the behaviour produced by linear interpolation because this will cause arbitrary Kdp values in case of noisy PhiDP profiles with large portions of missing data. 16 October 2013, 11:02:05 UTC
aed2e36 FIX: Removed error in addressing the variable kdp in function kdp2r. 16 October 2013, 08:36:38 UTC
6715625 DOC: Enhancing the documentation of the kdp_from_phidp function. 30 September 2013, 10:07:30 UTC
8e20438 MIN: Making the use of "mean" the default to compute MFB, and "median" optional. Using AdjustMFB was using the median to compute the mean field bias in order to make the correction more robust against outliers. In order to account for the name (MEAN field bias), the behaviour was changed. Now, the field bias is, by default, computed using the mean of all obs/est ratios. By using the argument "biasby" when calling the AdjustMFB object, you can decide to use the median (biasby="median") instead. 30 September 2013, 09:50:26 UTC
701a070 MIN: Considering the possibility that ErrorMetrics does not receive any valid obs/est pair. 30 September 2013, 09:44:44 UTC
445d5f1 REF: xvalidate method in adjust now returns NaN values for invalid data points. In the previous version, the xvalidate method only returned pairs of observed and estimated if both observed and estimated were valid values. This had a major disadvantage: You could not relate the values of the returned obs/est pairs to the original rain gage locations, because there was no mechanism for IDing and the length of the output arrays depended on the number of valid obs/est pairs. Now, the returned obs/est pairs have the same length as the original input of obs. If obs or est have invalid values, the corresponding entries are NaN. This way, we can relate the output to the exact rain gage locations via indexing. Basically, returning obs is redundant (because it is the same as the input obs). But we keep it this way in order to reduce the effect of this change to the API. 30 September 2013, 07:18:01 UTC
eb7cbeb FIX: Added "try" in __init__ so import does not raise an error if speedup is not available. 30 September 2013, 06:30:21 UTC
2de1534 FIX: Forcing fill_phidp to continue iteration after setting all gates to zero. 25 September 2013, 09:55:57 UTC
69a0e8c MIN: Relaxed conditions on the shape of input arrays for classify_echo_fuzzy. Now the shapes of the arrays do not need to have the same shape, but only need to be broadcastable (the two last dimensions need to be the same). 25 September 2013, 07:05:00 UTC
8017bef FIX: Removing a bunch of nasty bugs from the latest enhancements related to polarimetry. 24 September 2013, 14:48:47 UTC
d0298c4 ENH: Allowing for other decision variables to be passed to classify_echo_fuzzy. 24 September 2013, 12:42:07 UTC
eefb526 FIX: Removed error in assert statements in wradlib.clutter.classify_echo_fuzzy. Now debugging of all the new enhancements begins...sorry for the inconvenience. 24 September 2013, 12:08:27 UTC
f3658b2 FIX: Making wradlib.dp.texture applicable for arbitrarily dimensioned arrays. 24 September 2013, 12:02:47 UTC
1262b91 FIX: Deleted unnecessary import of module io in module vpr. 24 September 2013, 09:19:12 UTC
d3a341f ENH: Added function for retrieving rainfall intensity directly from specific differntial phase. See library reference of function wradlib.trafo.kdp2r for details. 24 September 2013, 09:18:43 UTC
013dfaa ENH: Added fuzzy echo classification based on Vulpiani (2012) to wradlib.clutter. See library reference for wradlib.clutter.classify_echo_fuzzy for details. A related utitlity function has been added to wradlib.util for defining trapezoidal membership functions. 24 September 2013, 09:17:35 UTC
591610a ENH: Added attenuation retrieval (pia) from specific differential phase (Kdp). See library reference for function wradlib.atten.pia_from_kdp for details. 24 September 2013, 09:15:11 UTC
409f787 ENH: Added new module dp containing algorithms related to dual-pol and differential phase. For details, have a look at the library reference. For speed up of phase unfolding, wradlib.dp also makes optional use of a shared library based on f2py (the extension module is called speedup). This is the first time use in wradlib. We should think about adding the compilation to setup.py, but for now, everybody who wants to make use of the speedy version needs to compile manually by executing 'f2py.py -c -m speedup speedup.f' (see also documentation). 24 September 2013, 09:13:50 UTC
6061d21 FIX: New implementation of wradlib.filter_gabella removed NaNs from original array. Line 209 of wradlib/clutter.py is: img[bad] = np.Inf This line changes the original image, but it was intend only as a local manipulation. In order to avoid this unintended behaviour, a local copy of img is generated in case argument rm_nans is True. 18 September 2013, 14:48:40 UTC
f8260df Removed thresholding at end of filter_gabella 11 September 2013, 13:28:51 UTC

13da47a NEW: empirical attenuation estimation due to wetting of the radome 06 September 2013, 14:25:12 UTC
d8382fb Changed code to make the shape of 3-D volumes generated by classes in wradlib.vpr to follow the convention (...,z,y,x) in order to make it consistent with the current polar convention (...,sweep,azimuth,range). 30 August 2013, 16:38:32 UTC
42921b7 Main results from today's sprinting session. A few functions to calculate mean profiles and to do simple corrections. 30 August 2013, 15:02:56 UTC
c8219ad ENH: Added new keyword argument "show" to vis.polar_plot2 in order to allow multiple subplots. The default value of show is True. If show is not explicitely passed, the behaviour of the funciton remains unchanged (i.e. the plot is immediately shown). If show is set to False, the figure is not plotted and further subplots can be added using the fig and aspos arguments of polar_plot2. 15 August 2013, 08:20:51 UTC
515c5a6 FIX: referring to revision no. 315, the Fix haven't worked proper, so here is hopefully a well-oiled update 27 June 2013, 13:58:02 UTC
7188a8c Removed PyTables as a dependency from setup.py and from gettingstarted.rst 24 June 2013, 11:01:14 UTC
759fe47 FIX: Removed PyTables dependency in wradlib.io PyTables was used to allow convenience import/export of data arrays to/from hdf5 files. This was implemented via wradlib.io.to_hdf5 and wradlib.io.from_hdf5. However, PyTables tends to conflict particularly with the netCDF4 module, probably due to conflicting hdf5 DLLs. So I changed wradlib.io.to_hdf5 and wradlib.io.from_hdf5 so that they use h5py instead of PyTables. This might cause a little bit of loss in compression efficiency and speed, but the conflicts where quite unpredictable and version dependent, so unfortunately, we had to get rid of PyTables. Call signature of the two conveneince functions stays the same, so users should not notice the change. 24 June 2013, 09:35:33 UTC
4e23454 FIX: Changed order in which netCDF4 and tables is imported. The former order procuced errors for the latest Python(x,y) release. 21 June 2013, 11:57:01 UTC
293233e Merged in kai_muehlbauer/wradlib_miub (pull request #8) New plot module in wrl.vis 14 June 2013, 09:55:04 UTC
e08ef3d FIX: a few changes concerning mainly the handling of keyword arguments during initialization and plotting. 13 June 2013, 14:40:27 UTC
23652f4 DOC: fixed typos, corrected some directorypaths 13 June 2013, 09:25:50 UTC
ce1714b DOC: a few more minor changes 12 June 2013, 11:19:43 UTC
744cfc7 DOC: moved class description of cg_plot from __init__ to class docstring, so that numpydoc puts it into the right place. 12 June 2013, 08:24:54 UTC

25e1a3f FIX: Modified syntax for executing decbufr under Linux and Mac 05 June 2013, 06:55:24 UTC
27942f9 FIX: Make sure decbufr is compiled under Mac during installation. 04 June 2013, 12:48:36 UTC
25226a1 FIX: Make sure that setup.py now copies decbufr to the installation directory even on Mac. 04 June 2013, 12:21:02 UTC
e586296 FIX: Removed limitation that prevents the bufr module to be called from Mac systems 04 June 2013, 10:00:51 UTC
af55176 FIX: Changed setup.py so that it will not produce an installation error on systems other than Windows and Linux. BUFR compilation is not yet available on Mac OS X from etup.py. Until we find a way to achieve this, the installation should only give a warning, but should complete without an error even on Mac. For now, setup.py will copy a dummy README.txt file to the wradlib/bufr_3.1 directory which states that BUFR compilation is not available on Mac, yet. 03 June 2013, 12:31:56 UTC
8cbfefb Synchronised required version numbers with Thomas in order to avoid merge conflicts. 03 June 2013, 12:13:12 UTC
36d46fe Added some TODO remarks into vpr.py 03 June 2013, 12:09:41 UTC
3e6f546 Changing required numpydoc version to 0.3 and pyproj version to 1.8.9 03 June 2013, 12:06:33 UTC
e13fe79 FIX: removed miscalculation at class-method adjust.AdjustBase.xvalidate in case using this class with more than 1 nearest neighbor for the best/median raws corresponding to the observations, the returned adjusted xvalidation pairs are wrongly not related to the original location, which is the same location as observation point, but spuriously to the location of the best corresponding raw bin; That leads unfortunatelly to better error statistic results by mistake. 29 May 2013, 13:13:20 UTC
0215f9f FIX: caught an error in correctAttenuationHB occured in case of attenuation overflow (AttenuationOverflowError was raised independently of the error-treatment mode 08 May 2013, 13:49:47 UTC
c2f2eee ENH: added batch file to automate making of html and ms-help documentation. This includes a few other settings concerning inline maths and an explicit setting of the pythonpath in case a different wradlib-installation is used for daily work (because sphinx uses imports when generating the documentation, and thus the pythonpath should be set so that it imports from the right modules). 22 March 2013, 10:31:23 UTC
a0c49fc DOC: reworked the linux installation part. 22 March 2013, 10:22:20 UTC
