I need to count the number of days with, for example, a temperature the threshold of >5° degrees, in a WRF-output with daily mean temperature values. Anyone knows or have a script example of how to do that?
I forgot to solve the question, but the function "dim_num_n" in NCL is the way to do it: https://www.ncl.ucar.edu/Document/Functions/Built-in/dim_num_n.shtml
