v10-01c
Because GEOS-Chem v10-01c was the version where we introduced the UCX chemistry mechanism, we performed two 1-month benchmark simulations:
- v10-01c_trop: 1-month benchmark with tropopsheric chemistry
- v10-01c_UCX: 1-month benchmark with UCX strat-trop chemistry (72 vertical levels)
--Bob Y. 13:15, 30 May 2014 (EDT)
Final recommendation for J-values
We were not able to include this final recommendation for J(HAC) and J(PAN) into the v10-01c_trop and v10-01c_UCX 1-month benchmarks. We will include these in the 1-year benchmarks for v10-01c.
