      related to the conv/large scale partitiong (tag b_AMM_H521MOPS_move2d)
  
2016-05-27 <anton.s.darmenov@nasa.gov> Tag: AeroChem-Heracles-5_2-b7
    * GOCART: Initially this tag had the edits related to the modified 
      temperature dependence of the wet removal efficiency factors that 
      used a linear ramp rather than a step function. The edits were in
      SU_GridCompMod.F90, ConvectionMod.F90 and WetRemovalMod.F90 
      (see asd-wet_dep-temperature_ramp tag). However, the results from 
      a test run showed noticeable changes in the AOD, so these edits 
      were reverted in CVS and in this tag until another more 'cleaner' 
      test is done to assess the impact of these edits.

    * Replaced CNV_QC (which contrary to the description in the export 
      spec is NOT convective condensate) with the sum of water and ice
      mass fractions of convective cloud (QLCN + QICN)
    * Fixed large scale wet removal when the model is run with the 
      2-moment cloud microphysics: replaced PFL_LSAN and PFI_LSAN with 
      DQRL (which is filled by the single- and two-moment cloud microphysics)

      in HNO3 wich is equal to 0.17*HNO3_GMI.

    * Apply (rather than omitting) emissions from volcanoes that are 
      below the 'surface' model layer.

      for now we rely on QFED climatology); the anthropogenic NH3 
      emissions are from EDGAR-v4.2.

	* Dust optical tables were updated to version 14.2

2014-02-06 <anton.s.darmenov@nasa.gov> , Tag asd-Ganymed-4_0_BETA8-a1
	* Changes implemented by Pete:
    1) Support for multiple instances of BC. BC_GridComp.rc 
    is changed to specify regional tags, and introduce BC_GridComp---full.rc 
    as analog to SU_GridComp—full.rc.  This change required updates as well to 
    GOCART_GridCompMod.F90 and Aero_GridCompMod.F90 to support handling of 
    optics for multiple BC instances. GOCART variable name checking was 
    more specific so that only the 'full' instances of BC and OC are put 
    in Aero bundle for radiation (and only SO4 and SO4v for sulfate). 
    Presumes full tracer names are OC(BC)PHILIC/PHOBIC.
    2) Updated SU_GridCompMod.F90 to permit volcanic data tables to include 
    also start time and end time for eruption emissions (required update to 
    SulfateChemDriverMod.F90). Also made change to add diagnostic calculation of 
    aerosol surface area (for StratChem). Finally, name handling for multiple 
    instances was improved so that volcanic instance (volc) is treated uniquely 
    whereas all other tags (which would nominally be regional/emission specific) 
    are given same names as tropospheric (full) tag. This is needed for 
    radiation diagnostics in module. Also made a small change in Chem_MieMod.F90 
    to accommodate more robust handling of multiple SU instance naming.
    3) Updated CARMA to latest, including coupling to GOCART SU as source of 
    gas H2SO4. Most changes relevant to sulfate simulation.

    This tag as well as the base tag Ganymed-4_0_BETA8 include setling of OC, BC and
    SU aerosols.

2014-02-04 <anton.s.darmenov@nasa.gov> , Tag asd-G4U-RRTMG-AeroState-r2
	* Mods for AERO state - work in progress. This is an intermediate tag 
	  based on Matt's 'Ganymed-4_0_UNSTABLE-RRTMGPU-withPGIedits'. 
	  The new Aero state code is run alongside the existing Aero bundle 
	  code for testing peroses.
	  The tag is zero-diff to Matt's tag if the Aero state is passive in 
	  in solar.

	* update to recent changes in GMICHEM (2011-12-27 notes)
	  including changes to GEOS_MoistGridComp.F90 and
	  GEOS_PhysicsGridComp.F90

2012-01-19 <peter.r.colarco@nasa.gov>, Tag AeroChem-Fortuna-2_5-b6
	* b5 was intermediary where we introduced the made the GOCART
	  aerosols unfriendly to MOIST and used the offline convective
	  scavenging code to do both convective mixing and scavenging.
	  This is applied for all aerosols DU/BC/SS/SU/OC under GOCART.
	* b6 maintains this but also changes the name of the offline
	  scavenging module to be more consistent with other stuff
	  under Chem_Shared.
	* b6 also brings major changes under the hood to CARMA
	* TO DO: tune GOCART aerosols for new scavengin
	         bring BC/OC/SS/DU/SU code back to trunk (on branch for now)
	         update to recent changes in GMI (requires new restart for
	         moist)

2012-01-05 <peter.r.colarco@nasa.gov>, Tag AeroChem-Fortuna-2_5-b4
	* Fix a bug in ras.F90 where boundary layer aerosol was no scavenged

2011-12-27 <jon.e.nielsen@nasa.gov> HEAD
        * GMICHEM: Enable lightning NO production based on flash rates imported
          from MOIST (LFR).

	  GEOSadas-5_7_2_p3_UNSTABLE

	  including hooks for various emission efficiency factors based on
	  Fan and Toon (2011).  Also, changed sense of SeasaltEmission
	  routines in Chem_Shared
	* CARMA code now passes an AERO and AERO_DP bundle.  AERO
	  bundle tested and available for radiation.  Note: you must fit
	  the CARMA aerosols into a structure similar to GOCART to get
	  optical tables read correctly. This includes filling
	  Chem_MieRegistry.rc with correct number of tracers and names
	  (e.g., doing_DU = YES and provide CARMA type names).  NOTE
	  ALSO: there are numbers hard coded in radiation (see
	  MAX_NUM_RADIUS in GEOS_SolarGridComp.F90 and
	  GEOS_IrradGridComp.F90 and the associated sorad.F90 and
	  irrad.F90.  These numbers need adjustment for a larger number of
	  size bins.
	* Bump up dust and seasalt emission scaling factors to account for
	  lower surface wind speeds in Fortuna-2_5 based tag

2011-09-21 <jon.e.nielsen@nasa.gov> Tag: Hypatia-1_0_UNSTABLE_JEN
        * Generalized the connectivities between GMICHEM and GOCART 
	  to support those cases in which fewer than all five GOCART 
	  dust/aerosol classes are being imported to GMICHEM. Also allows

        * GMICHEM: New gmi_acg.pl, along with mapl_acg.pl, are run in a three-
          step process to generate code fragments for declaring and getting
          pointers and filling some export states.  Scavenging and deposition
          export specs have been added for several species, in addition to HBr 
          (see entry immediately below).  Tested in Fortuna-2_4_BETA1 and

        * Removed the GEOS-4 references in CO2.
        * Rewrote the PBL partitioning for biomass burning emissions in

	  were not summed over the bins.

2010-11-23 <anton.s.darmenovo@nasa.gov>
	* Maring correction to dust settling velocity. The correction
	  is not applied by default. It can be enabled by setting the

	* Chem_Base/Chem_Registry.rc: added missing doing_CH4 resource;
	  similar changes in CMIP and PIESA rc files.
	* CO_GridComp: fixed biogenic emission bug; emissions were being
	  scaled twice and sometimes uninitialized leading to
 	  non-reproducibility. GNUmakefile brought to trunk and rc file
	  modified to refer to proper CH4.

2010-11-12 <arlindo.dasilva@nasa.gov>, Tag AeroChem-Fortuna-2_3-r1

	  to be assumed scaled 0 - 1.  In components making Chem_MieQuery
	  calls removed the division of w_c%rh by 100, so now the code
	  uniformly expects rh scaled 0 - 1.
	
2010-04-13 <arlindo.dasilva@nasa.gov>, Tag AeroChem-Fortuna-2_1-m3

	* Initial implementation of GOCART/GMI coupling; this will be
	  revised later to include the EXTERNAL_CHEMISTRY bundle as
	  an import to GOCART.
	* CHEMISTRY now exports an standard set of RATS
	  which is then connected at the Physics level; StratChem/GMI
	  tracer variable names no longer qualified by the component name
	  (e.g., it is now "CO" instead of "GMI::CO"); GOCART variables
	  still qualified with GOCART:: (to be fixed in the next release).
	  
	
2007-07-11 <arlindo.dasilva@nasa.gov>, Tag gAdas-1_5beta10p14-c1
