Dear all,
I am using CMAQv5.4-ISAM for analysis.
When I run Layer 2 CCTM, it says “User specified ISAM region - HZS - not found in available emissions regions”, but I am assured that the region.nc file contains the required regions.
After reviewing the information and changing the &Desid_RegionDef section of the CMAQ_Control_DESID.nml file.
when I run CCTM again it says “Region HZS on file ISAM_REGIONS contains a value greater than 1. The expected range is 0-1.”, again I can guarantee that the values are all in the range 0 to 1.
I can’t find out why the problem occurs and would appreciate an answer, thank you very much!
It looks like you had some files/pictures you intended to upload that I am not able to access. Could you try uploading them again?
May I ask how you are guaranteeing that no values are greater than 1.0 in your regions file? Have you tried, for example, to retrieve the maximum value of that variable using NCO tools or Python? Have you confirmed that all numbers in your file are of type real?
You will need to check the data on the file. The description is just a text field that can be inaccurate.
To see the range of the variable in the file, try loading it in ncview or VERDI, or inspecting it in R or python. Alternatively, you can use the m3tools program m3stat.
Thank you for your reply! I checked the data on the file, re-analyzed it, and then it has been able to run successfully! I speculated that there might have been a problem with the region file production or a server caching issue, which has now been resolved. Thank you very much for your replies and answers!
