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.
