1. I can't open the products because they have a .bz2 extension. What should I do?
All products are compressed, to save storage space and network bandwidth. To decompress them you should use the bzip2 application available here.
2. How can I open and visualize LSA-SAF products in my computer?
To open our products you can use HDF Viewer and/or Panoply.
3. LSA-SAF EPS Products are hard to decode with HDF Viewer and Panoply. Is there an alternative to these two?
Yes. The European Space Agency has developed SNAP and we recommend it to open EPS products. Tutorials are available here.
4. I don't know how to determine the latitude and longitude for each pixel in the LSA-SAF images.
The latitudes and longitudes are specified in HDF5 auxiliary files, which can be found at the "User Support/Auxiliary Data". Furthermore, you can use the MSG Geolocation Routines available at "User Support/Auxiliary Tools".
5. When does the MSG satellite start doing a full-disk scan of our planet?
A full-disk scan starts at the designated timeslot of a product. Timeslots vary between LSASAF products.
For example, the temporal frequency for Land Surface Temperature production is of 15 minutes, whilst Daily Surface Albedo has a temporal frequency of 1 day.
6. What is the acquisiton time for each MSG satellite full-disk scan?
The acquisition time for the satellite to do a full-disk scan is of 12 minutes.
7. Can I get precise time information for when the satellite scanned a particular region of our planet?
In case you need this information, please contact the LSASAF Helpdesk.
