Hello everyone,

I have been trying to use 'wrf_user_interp_level' to extract a few variables such as vertical wind velocity, QVAPOR and relative humidity in different pressure levels (850, 700 and 500 hPa levels). When I tried to extract vertical wind velocity and QVAPOR at every level, I found '9.97E+36' value at multiple different points for the specific event. But relative humidity provides normal values (between 0 to 100).

It seems to me that the interp function is using '9.97E+36' as FillValue or missing value alternatives. My concern is why I am getting missing values for wind and QVAPOR at such a high level (500hPa)? In addition, if the specific vertical level is not present, aren't we supposed to get a missing value for relative humidity as well?

Thank you for your help.
