Data Summary: CMAQv5.3+ output data for a 07/01/2016 - 07/14/2016 simulation over the Southeast US. Note:The datasets are on a Google Drive. The metadata associated with this DOI contain the link to the Google Drive folder and instructions for downloading the data.
File Location and Download Instructions:
File Format: The 2016 model output are stored as netcdf formatted files using I/O API data structures ( https://www.cmascenter.org/ioapi/). Information on the model projection and grid structure is contained in the header information of the netcdf file. The output files can be opened and manipulated using I/O API utilities (e.g. M3XTRACT, M3WNDW) or other software programs that can read and write netcdf formatted files (e.g. Fortran, R, Python).

CMAQv5.3.1 Model Output Files The Southeast benchmark output data for v5.3.1 is slightly different from what was released with v5.3 as described in the CMAQv5.3.1 Release Notes FAQ.

CMAQv5.3.2 Model Output Files The Southeast benchmark output data for v5.3.2 is slightly different from what was released with v5.3 as described in the CMAQv5.3.2 Release Notes FAQ.
Note about v5.3.2 benchmark data: CMAQv.5.3.2 output is for a two day benchmark case (July 1-2, 2016), rather than the full two week period. Output is provided for both the debug mode turned off (Optimized) and the debug mode turned on (Debug) version to allow the user to compare their answers to either. To reduce the impact of compiler flags on the model output, it is preferable to use the debug version. To compare model results obtained while achieving faster run times due to compiler optimization, the Optimized version output is also provided.

CMAQv5.3.3 Model Output Files Benchmark output for v5.3.3 is provided however the output is identical to the output from v5.3.2 with the exception of HONO dry deposition as described in the CMAQv5.3.3 Release Notes FAQ. The HONO dry deposition update in M3DRY and STAGE leads to small changes (on the order of 1e-5) in HONO dry deposition in the dry deposition output files for the base model and ISAM benchmark.
