Top_MSG_BT108
How to use this plot
Make sure you have the required datafields (msg_brightness_temperature_108)
You can use it as is by appending this code into your mswms_settings.py:
from mslib.mswms.mpl_hsec_styles import HS_Meteosat_BT108_01
register_horizontal_layers = [] if not register_horizontal_layers else register_horizontal_layers
register_horizontal_layers.append((HS_Meteosat_BT108_01, [next(iter(data))]))
If you want to modify the plot
Download this
file
Put this file into your mswms_settings.py directory, e.g. ~/mss
Append this code into your mswms_settings.py:
from Top_MSG_BT108 import HS_Meteosat_BT108_01
register_horizontal_layers = [] if not register_horizontal_layers else register_horizontal_layers
register_horizontal_layers.append((HS_Meteosat_BT108_01, [next(iter(data))]))
