v3.2.0 - Default tile-space HISTORY output to nc4; bug fixes

• 0-diff vs. GEOSldas v20.1.0 except:

  • Not 0-diff for ASCAT and CYGNSS data assimilation.

• New features:

  • Changed default format of tile-space HISTORY output to nc4 (GEOSldas_GridComp PR #144).
  • Added reader for surface meteorological forcing from S2S-3 (GEOSldas_GridComp PR #138).

• Minor changes:

  • Cleaned up ldas_setup; split out ldas.py and setup_utils.py; restored ntasks-per-node option (GEOSldas_GridComp PR #107).
  • Enable remapping of landice restarts from ldas_setup (GEOSldas_GridComp PR #146).
  • Added matlab reader for binary mwRTM vegopacity file (GEOSldas_GridComp PR #142).
  • Commented out static QC mask in CYGNSS obs reader (GEOSldas_GridComp PR #151).
  • Update GEOSlandassim_GridComp/io_hdf5.F90 to allow for use with HDF5 1.14 (GEOSldas_GridComp PR #139).

• Bug fixes:

  • Fixed bug in ASCAT EUMET soil moisture obs reader; bumped max_obs limit (GEOSldas_GridComp PR #148, GEOSldas_GridComp PR #151).
  • Provide default "zoom" value for remap_restarts yaml file (GEOSldas_GridComp PR #137).
  • Fixed Restart=1 when the domain is not global (GEOSldas_GridComp PR #107).

v2.0.0 - Multi-sensor soil moisture and snow cover assimilation, M21C met forcing

• 0-diff vs. v1.1.0.

• Science changes:

  • New update_type for joint 3d soil moisture and 1d snow analysis (Tb+sfmc+sfds+SCF obs) (PR #68).
  • Updated subroutine read_obs_sm_ASCAT_EUMET() to work with both original and revised file name templates (PR #69).
  • Added CYGNSS soil moisture reader (PR #76).
