satpy.readers.mwr_l1b module

Reader for the level-1b data from the MWR sounder onboard AWS and EPS-STerna.

AWS = Arctic Weather Satellite. MWR = Microwave Radiometer.

AWS test data provided by ESA August 23, 2023.

Sample data for five orbits in September 2024 provided by ESA to the Science Advisory Group for MWS and AWS, November 26, 2024.

Sample EPS-Sterna l1b format AWS data from 16 orbits the 9th of November 2024.

Continous feed (though restricted to the SAG members and selected European users/evaluators) in the EUMETSAT Data Store of global AWS data from January 9th, 2025.

Example:

Here is an example how to read the data in satpy:

from satpy import Scene
from glob import glob

filenames = glob("data/W_NO-KSAT-Tromso,SAT,AWS1-MWR-1B-RAD_C_OHB__*_G_O_20250110114708*.nc"
scn = Scene(filenames=filenames, reader='aws1_mwr_l1b_nc')

composites = ['mw183_humidity']
dataset_names = composites + ['1']

scn.load(dataset_names)
print(scn['1'])
scn.show('mw183_humidity')

As the file format for the EPS Sterna Level-1b is slightly different from the ESA format, reading the EPS Sterna level-1b data uses a different reader, named eps_sterna_mwr_l1b_nc. So, if specifying the reader name as in the above code example, please provide the actual name for that data: eps_sterna_mwr_l1b_nc.
