Completed CO2 downscaling
 
The model successfully runs to completion for ZLND  with functional CO2
downscaling. The linearly downscaled CO2 data have been verified
within the GCAM repo code, but not yet in the fortran ehc code
(giac repo). Convergence downscaling has not been verified. Restarts
work properly. The gcam namelist has been updated to add several
options for convergence downscaling and the gcam co2 passing namelist
item has been corrected in name. A shell script has been added to
gcam/tools that generates the new input base co2 gridded files.
The fortran floating point exception checks are still off because
the model still fails due to untrapped GCAM nans if these are on
(which usually is only when DEBUG=TRUE). This allows for DEBUG to
be set to TRUE and for the model to run. The configuration for
the boost library for the ehc/gcam now points to the files in
the gcam repo for portability. The xerces library configuration
has been removed as it is no longer needed by GCAM.  The three repo
branches (e3sm, giac, gcam) at this commit work together
(at least for ZLND), and thse branches are set in the .gitmodules files.

                  A description of share

This directory collects code shared between various models in a CIME-coupled
system.

Motivation for this code sharing includes:

- facilitating consistent physics between all models.  For example, uniform
  solar-zenith-angle/orbital calculations and uniform physical constants.
- avoiding the need for redundant implementations of commonly needed
  functionality.  For example netCDF file reading, basic mapping (re-gridding)
  functionality, and common character string manipulations.

While a runtime library is made from this code, some of this shared code is accessed
by including the appropriate source code directory path during compile time.

Current subsets of shared code include:

util - very generic, general-purpose Fortran code that is likely to be useful to all
      CIME components.  CIME components may be explicitly required to use some
      parts of this code, for example the physical constants module.

RandNum - various software random number generators

esmf_wrf_timemgr - Fortran implementation of ESMF Time Manager (5.2.0rp1)

timing - custom version of the GPTL.

streams - code for managing "streams" of data files.

test - unit tests for some of the share code


This code was originaly part of CIME in CIME/src/share. Brought in to E3SM
from CIME hash b95a28b417b9b27 from May 4, 2021
