README -- describes contents of v11-02a/Run1 31 May 2017 GEOS-Chem Support Team geos-chem-support@as.harvard.edu This benchmark simulation is GEOS-Chem v11-02a-Run1. The following updates since GEOS-Chem v11-01-public-Run0 have been applied: VERSION | FEATURES INCLUDED | APPROVAL DATE ======================================================================= v11-02a - Update chemistry rate constants based on TBD JPL Publication 15-10 - Fixes to correct ALK4 lumping issue - PAN updates (including emissions, deposition, species, chemistry) with the following updates removed: * Biomass burning injection heights * Partitioning of NOx into PAN and HNO3 - Monthly mean NEI2011 emissions - Bug fixes in the GEOS-Chem sulfate_mod: * Fix error in production of SO4s and NITs in SEASALT_CHEM * Fix bug in CHEM_NIT * Fix for sulfate production in HET_DROP_CHEM * Fix bugs in sulfate chemistry routines - Fix bug in dry deposition aerodynamic resistance - Bug fix in cos(SZA) for start of timestep - Include TOA pressure when calculating dry pressure edges This benchmark simulation uses the standard chemistry mechanism (i.e. tropchem + UCX + SOA ) and 72 vertical levels.
