Global High Resolution Dust Emission Inventory for Chemical Transport Models

<strong>Overview:</strong><br> ================================================================================== Offline dust emissions in 2016 are now available at 0.25° x 0.3125° resolution. This dataset is calculated using the native resolution GMAO meteorology (GEOS-FP) fields. Codes and Instructions (README file in the GitHub repository) to generate these offline emissions can be found on GitHub. The offline emissions in this database have no scale factor applied, so users should apply the required scale factor in their application. Suggested scale factor to make the global total annual dust emission to 2000 Tg is 5.7141e-4. <br> <strong>Zip File Details:</strong><br> =============================================================================== 2016.zip contains daily (366 in total) netCDF files (stored in monthly folders) of global gridded hourly mineral dust emission flux rate. Individual file: /YYYY/MM/dust_emissions_025x0.3125.YYYYMMDD.nc Resolution : 0.25 x 0.3125 grid (721 x 1152 boxes)<br> Units : kg m-2 s-1<br> Timestamps : Hourly, 2016<br> Compression : Level 1 (nccopy -d1)<br> Chunking : nccopy -c lon/1152,lat/721,time/24 Variables in each file: EMIS_DST1, EMIS_DST2, EMIS_DST3 and EMIS_DST4 represent dust emission flux rate in four size bins (0.1-1.0, 1.0-1.8, 1.8-3.0, and 3.0-6.0 micro in radius). *<em>Version 2020_v1.0 of this dataset was produced to accompany the following manuscript:<br> Meng, Jun, R.
