How can I filter GRIB data?

Step-by-step guide

You need to use the GRIB Filter icon, which is implemented as the read() function in script. The following Python example shows how to read a GRIB file and extract temperature fields on pressure levels out of it:

1. import metview as mv
   f = mv.read(source='my_grib_file', param='t', levtype='pl')

2. Alternatively the GRIB file can be read into a fieldset object and you can apply the filter on it:

3. import metview as mv
   g = mv.read('my_grib_file')
   f = mv.read(data=g, param='t', levtype='pl')
