Overview

CHEMISTRY RELEASE date TBD

Will contain everything in v8-01-04 plus the following:

  1. Glyoxal chemistry (May Fu)
  2. Updated J(O1D) cross sections (Lin Zhang)
  3. Updated reaction rates (Jingqiu Mao, Dylan Millet, Palmer group @ U. Edinburgh)
  4. HO2 uptake (Lyatt Jaegle)
  5. Updated dust single scattering albedo (Randall Martin)

1-year benchmarks

SUMMARY:

  1. v8-01-04 Run2 vs. v8-01-04 Run1 is a clean comparison between the GEOS-5.0.1 and GEOS-5.1.0 met products.
  2. v8-02-01 Run0 vs. v8-01-04 Run2 is a clean validation the new chemistry mechanism and updates that were added into v8-02-01.
  3. All runs used the same:
