Preparations LEO

• Choose between Linux and Windows: Uncomment/comment the right opsys line
• Determine location of EMCtools and EMCdata: adapt toodrp and datdrp
• If desired define a viewer (will be used with option '-v')

• default segdir (if -src option isn't used)

• Metop-B and C
• Sentinel-3A and B

Examples

python3 Metop.py -t 20220324 -dry                           dry run, show settings (in this case: the defaults)
python3 Metop.py -t 20220324 -dry f                         dry run, show also files selected
python3 Metop.py -t 20220324 -sat BD                        use Metop-B, day pass
python3 Metop.py -t 20220324 -sat BD -area westminster      same, choose area
python3 Metop.py -t 20220324 -sat BD -composite overview    same, choose composite
 
python3 Metop.py -t 20220324 -sat XN                        use combined Metop-B and C, night pass
python3 Metop.py -t 20220324 -sat BD -sp                    use Metop-B multiple passes

python3 Metop.py -t 20220324 -sat BD -src C:\aaa\bbb        use source files in this location
python3 Metop.py -t 20220324 -sat BD -dst C:                location of output file
python3 Metop.py -t 20220324 -sat BD -o anc.jpg             name output file
python3 Metop.py -t 20220324 -sat BD -tle C:\weathet.txt    TLE location and file
python3 Metop.py -t 20150324 -sat BD -histtle               get/use tle from spacetrack

python3 Metop.py -sat BD -fl filelist.txt                   Use files in filelist instead of collected items by date (no -t option)

Note: You can specify codec, default is DIVX. For some reason WebM (VP09) doesn't work.

Running this script will create a movie and update it while MSG data is coming in.
Uses MSGx.py and movie_funcs.py
Needs: conda install watchdog (use pip if you don't use conda)

At the top of this file, specify:

• which satellite (or type: RSS, IODC, FULL)
• path where incoming files are saved
• max. length of movie
• area, composite

• satpy_selector.py

You need also:

• GEO scripts
• LEO scripts

python3 satpy_selector.py msg

This gives the gui: (geo and leo)

Now:

• Select type of satellite, this will refresh the list of available data
• Select a line in the list of available data
• for polar sats choose day or night
• choose an area (default=built-in defaults in the used script)
• choose a composite (default=built-in defaults in the used script)
• click 'View', will generate an image and open a viewer
• Or click 'Gen', will only generate an image

satpy_selector.py contains 2 lists of satellites including the command to execute them:

• geosattypes
• leosattypes

• exe_cmd=''
  • This executes scripts like MSGx.py. The scripts must be at a location included in the searchpath and must be executable
• exe_cmd='python3 <full_path_to_scripts>'
  • This executes scripts like python3 /home/user/tools/MSGx.py (if <full_path_to_scripts> is /home/user/tools/)

satpy_selector.py uses lists defined in satpy_settings.py:

• data_loc: contains name and location of files. Name may be any name you like; location must be full path. A location normally should contain data of one satellite, but may also contain a mix of different satellites.
• regio_list: this list contains area's bound by min/max lon and lat. It is used to divide the very long list of area's, defined in the areas.yaml files, into manageble portions. You may adapt this list, including names and area def's. The result is used to create a 2-steps menu 'area' in satpy_selector.py:

  

Location of files

• The main .py files (MSGx.py, Metop.py etc.) are all executable. You may put them in a location pointed to by searchpath (Linux: $PATH) and then execute them from anywhere like:
  • Metop.py -t .......(etc.)
    
  Or:
  • python3 <path_to_py>/Metop.py -t .....
  in which case you need to add the location of the .py files.
• Files used by the main .py files need to be put at the same location:
  • satpy_ecast_rts.py

Problems with tkinter

• MSGx.py (native files from internet but also files from eumetcast)
• Metop.py (only files from eumetcast!)
• satpy_selector.py

• Metop.py (native files from internet); although satpy can handle them the files are too big for a Pi!

• Metop files from Eumetcast are 28 Mbyte (after unzipping); each file covers 3 minutes. Needs about 2G RAM for processing.
• Metop files from internet are 980 Mbyte!!! (after unzipping); each file covers about one orbit, so 90 minutes. Needs about 10 G RAM for processing (on a 64-bits PC).
