WACCM results for a subset of the globe and a range of dates can be downloaded from this page. Output is provided every 6 hours. Each request is provided as a single netcdf file. We strongly recommend that you download a single day for your region to check the file size and then request a range of dates that will result in a manageable file size. Questions about WACCM and requests for additional dates can be addressed to Dan Marsh (marsh at ucar . edu).
The WACCM forecasts are driven by meteorological fields from the NASA GMAO GEOS-5 model. This simulation uses anthropogenic emissions from CEDS provided for CMIP6, with emissions for 2014 used for this year. Open fire emissions are from FINN-v1 (Wiedinmyer et al., Geosci. Model Devel., 2011). The results are at 0.9x1.25 degrees with 88 levels. Each file (global for 1 day) is 5.2GB: https://www.acom.ucar.edu/waccm/DATA
The 'date' and 'datesec' variables contain the date and time of the WACCM output. To verify the date of the downloaded files, please use 'ncdump -v date'. The program ncview does not properly interpret the 'time' variable and calculates an erroneous date.
WACCM results are available for January 1, 2018 until 10 days from now.673 downloads since 2018-01-23.
