Processing MTG Data

[woo...@gmail.com]

Hi

I am trying to process the MTG data and I get the following errors

I am running with Satpy 0.51 and all other packages are up to date

Many thanks

Graham

Hi,

What were the commands that resulted in the trace you show below? Which
composites did you load for example?

Hi these are the scripts I am running based on files from Ernst Lobsiger

Hi, Graham.

It looks like GEOstuff.py is setting the config directory to a wrong one. That's my guess. Please, check these two lines

# Replace environment variable 'SATPY_CONFIG_PATH'
config.set(config_path = [toodir + '/userconfig'])

tooldir is /home/eumetcast/SPStools in the script.

Regards,

José

Hi Jose

Thanks for your reply

I should have mentioned that I am running the scripts on a Windows PC so the user_config should be pointing to the correct location

I:/SPStools/userconfig

I think it must be because all my other scripts for MSG, GOES16/18 and Himawari work correctly

Warm Wishes

Graham

[José Daniel Gómez de Segura]

Ok, sorry and thank you, because I've just started to play with MTG from the DataStore and I may need the same scripts.

By the way, don't download the Q1 chunk with eumdac unless you want South Africa (or Q4 for Europe). The docs are... 'inverted'. :-)

Regards,

José
