|
| Improved wet scavenging from Luo et al. (2020) (as option) | Gan Luo (Albany) Fangqun Yu (Albany) |
Wet deposition |
|
Bug fixes:
|
Christoph Keller (GMAO) | Bug fix | |
| Updates that will NOT affect full-chemistry simulations | |||
| Bug fixes: | Eloise Marais (Birmingham) | Bug fix Diagnostics |
|
| Trace metal simulation | Junwei Xu (Dalhousie) | Specialty simulation |
|
| Features only affecting GCHP: | |||
New data directories
The following data directories have been added or updated in this version. You will have to download the directories relevant to your simulation.
| Inventory | Type | What was added? | Directory |
|---|---|---|---|
| CEDS | Default | CEDS v2 emissions through 2019 | HEMCO/CEDS/v2021-06 |
| Yuan-processed MODIS LAI | Default | Updated BNU v6/Yuan-processed MODIS LAI product (2000-2020) | HEMCO/Yuan_XLAI/v2021-06 |
| TRACE_METALS | Optional | Canadian (CAC) and US (NATA) emissions (2011-2013) for the trace metals specialty simulation | HEMCO/TRACE_METALS/v2021-06 |
1-month benchmarks
This version will require 1-month full-chemistry benchmarks, with and without Luo wet deposition.
1-year benchmarks
This version will require 1-year full-chemistry and transport tracer benchmarks, with and without Luo wet deposition.
