Alternative Satpy scripts

Some alternative scripts are described here. The differences with the original (v4.1) scripts are:

One script for each satellite type, e.g. one for MSG2,3,4; one for Metop-B,C etc.
Mandated options for Date and (for LEO's) day/night pass have -t and -dn options
Other options for area, composite, source location, destination location,output filename etc.

Alternative scripts

GEO scripts

The scripts available in SPStools/GEOscripts are for one area/composite(set) only. You need to copy scripts to another filename for each different area/composite-set you want.

Instead (or also) you can use the scripts described below. These GEO-scripts are very similar to the original ones, but they contain options for composite, area etc.
So there is no need to copy/maintain multiple scripts for each satellite/composite/area combination.

The GEOstuff.py available here is very similar to the original one, but it contains support for:

native MSG format

out-of-service sats like MSG1

HIMA9 added

HIMA: mixed compressed an not compressed (no need to define decomp in HIMA.py)

Stop processing if needed channels are missing

search rule of MTI1 adapted

Besides 'area' (string) geo_images() also accepts struct. sarea from satpy's get_area_def()
this is for resizing for movie frames; sarea contains also new size of image to generate

selection for movie or not (-m commandline parameter), including resizing and adapting subdir for generated files

If you don't need that you can use the original GEOstuff.py.

Notes:

the MSLP scripts are not supported (yet).
subdir 'frames' is selected in case of option -m or if the area name ends with '_rss'.

Usage

 ./<script>.py [-h] [-t T] [-sat SAT] [-src SRC] [-dst DST] [-o O] [-area AREA] [-composite COMPOSITE] [-m ] [-v [V]]


options:
  -h, --help            show this help message and exit
  -t T                  time: YYYYmmDDHHMM
  -sat SAT              satnr: 4, 18, ...
  -src SRC              source dir., MUST be absolute path!
  -b B                  bulk: y|n.
  -dst DST              destination dir.
  -o O                  output file
  -area AREA            area 
  -composite COMPOSITE  composite 
  -m [M]                reduced size, for movie
  -v [V]                Start viewer

LEO scripts

The scripts available in SPStools/LEOscripts are for one area/composite(set) only. You need to copy scripts to another filename for each different area/composite-set you want.

Instead (or also) you can use the scripts described below. These LEO-scripts are very similar to the original ones, but they contain options for composite, area etc.
So no need to copy/maintain multiple scripts for each satellite.

The LEOstuff.py available here is very similar to the original one, but it contains support for:

corretion 'dt += timedelta(minutes = 3)'
auto-download of TLE's, also for dates in the past
out-of-service sats like Metop-A.

If you don't need that you can use the original LEOstuff.py.

Usage

 ./<script>.py [-h] [-t T] [-dn DN] [-sat SAT] [-mp MP] [-histtle] [-src SRC] [-dst DST] [-o O] [-area AREA] [-composite COMPOSITE]

  -h, --help            show this help message and exit
  -t T                  time: YYYYmmDD
  -dn DN                D|N, D=Day, N=Night
  -sat SAT              A|B|C|X
  -mp [MP]              do multipass
  -histtle [HISTTLE]    get historical tle from spacetrack
  -src SRC              source dir., MUST be absolute path!
  -b B                  bulk: y|n.
  -dst DST              destination dir.
  -o O                  output file
  -area AREA            area 
  -composite COMPOSITE  composite 
  -v [V]                Start viewer

Selector for satpy

NOTE: needs to be tested on Windows!

Updated 01-02-2024

satpy_selector_20240201.zip

This selector is a simple gui using above scripts (both GEO and LEO) You need also:

GEO scripts
LEO scripts

You must add locations of your raw files into satpy_settings.py. This will create a menu in the selector with all locations. 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

Best is to start this in a command shell so you can see (error-)messages generated by the activated scripts, and also the path+name of the generated image file.

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

geosattypes
leosattypes

Don't change these lists. Note variable exe_cmd. You can choose here 2 methods to execute the scripts:

exe_cmd=''
- This executes scripts like MSG.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/MSG.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:
composite_list: list of available composites for each satellite. This list may be adapted/extended; not all composites may be added yet.
The Composite menu is created/adapted if another satellite is choosen.

Note: For directories, for windows, use '/', not '\'.

New:

If a geostationair satellite is choosen then, if channels are in different files, these will be added as sub-items in the tree:

If a polar satellite is choosen and earthmap.gif exists then the track and selected area will be shown:

Location of files

The main .py files (MSG.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:
- GEOstuff.py, LEOstuff.py

Location satpy_selector.py: same location as for Metop.py etc.

Area visualizer for satpy

(version 2024.01.05)

This is a simple gui which shows all satpy-defined area's on an earth map. User-area's are also shown; all areas.yaml files known by satpy are used.
Note: The location of the users-areas.yaml is defined by variable $SATPY_CONFIG_PATH.
Zip-file contains both Python-script and an example earthmap file, but you can use any plate carree map with any size (width=2x height). No SPStool files are needed, just the satpy installation.

(Note: this is also implemented in the satpy_selector, which shows then both track of selected satellite and selected area.)

Usage:

  -h, --help  show this help message and exit
  -s S        size (multiplier fact.) image (1=org. size)
  -f F        plate carree image file
  -ac AC      colour area
  -m [M]      use menu instead of buttons

Version 20240105:

Fixed: last item in areas list
Fixed: empty regio
