Describe your issue in detail
I am still new at using CAMx for real world applications, and am preparing a CAMx annual run using input files from the OSAP 2022 modeling platform on this AWS website: OSAP 2022 Modeling Platform - Registry of Open Data on AWS
I am hoping someone has done this before and can help guide me through the process. My questions are as follows:
- Are the input datasets from the website above in CAMx v7.32-ready format? Specifically
https://epa-2022-modeling-platform.s3.amazonaws.com/12US2_wrfcamx/
https://epa-2022-modeling-platform.s3.amazonaws.com/wrfcamx/
https://epa-2022-modeling-platform.s3.amazonaws.com/bcon/HEMI_CMAQ_12US2_CAMxBC/
https://epa-2022-modeling-platform.s3.amazonaws.com/bcon_v2/HEMI_CAMQ_12US2_CAMxBC_v2/
https://epa-2022-modeling-platform.s3.amazonaws.com/emis/2022v2/CAMx/
https://epa-2022-modeling-platform.s3.amazonaws.com/MCIP/12US1/

If any, which datasets are CAMx-ready?
-
For the rest of the datasets, are there lists of input datasets that specifically require the use of one or more of the support software programs listed on this CAMx webpage?
What version of the other software are you using?
I am using CAMx v7.32 which supports both Fortran binary and NetCDF input files.
What steps have you taken to resolve this issue already?
I have compared these datasets to those from the CAMx test case and tried to match like for like, but it is unclear whether there is just one standard NetCDF data format or multiple formats based on the dataset contents. I have also tried Verdi to open some NetCDF files, but not all of the NetCDF files are readable using Verdi. Most can be viewed using ncdump, but that’s no guarantee that they are in the CAMx-ready format. There are a few datasets that I recognize as SMOKE output, and know that they require preprocessing.
This is the most complete collection of CAMx input data I have found, but it would be very helpful to know if there are alternative sources which require minimal CAMx preprocessing. I would really appreciate some guidance before I go ahead and download a year’s worth of these input files, given the limited disk space we presently have and the required preprocessing for other datasets.
I have only been subscribed to the CAMx mailing list for the last 2 years, so I don’t have access to any relevant discussions that occurred before then. Any assistance is much appreciated!
