                        Shortwave Radiation Top-Of-Atmosphere
  --fetch-files         fetch all files that match query (default is just to
                        print files that match query
  --debug               show debug info

For example, to query for full-disc data of the Total Precipitable Water (TPW) product near 30th January 2020 at 14:00 UTC run:

$> python -m satdata.cli --region F --product ACHA 2020-01-30T14:00

Or use the module directly from python:

import datetime
import satdata


t = datetime.datetime(day=16, month=1, year=2020, hour=16, minute=0)
dt_max = datetime.timedelta(minutes=20)

cli = satdata.Goes16AWS()
keys = cli.query(time=t, region='F', debug=True, dt_max=dt_max)
fn = cli.download(keys[0])[0]
