CAM-chem 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 CAM-chem and requests for additional dates can be addressed to Rebecca Buchholz (buchholz at ucar . edu).
Direct data download is also avalailable from: https://www.acom.ucar.edu/cam-chem/DATA/
The 'date' and 'datesec' variables contain the date and time of the CAM-chem 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.
CAM-chem results are available for January 1, 2010 to December 31, 2018.
For other dates, please contact Rebecca Buchholz (buchholz at ucar . edu).
