5 overpass download

[annajungbluth]

Overview of changes:

• added script (downloader_msg_modis_overpass) to download msg timestamps whenever MODIS has an overpass. Note that an equivalent script does not yet exist for GOES
• changed try/except loop in msg download.py to avoid the program from crashing when no product or file is found. With this, I was able to download data for all of 2010
• added functionality to add either specific timestamps, or date/time ranges to GOES and MSG download.py. This way, it's easier for the users to query specific data (for instance with MODIS overpasses)
• added scripts to download MSG data in monthly chuncks. Even with some refactoring, the download is very slow, so it's better to parallelize.

Looks good. The only think I suggest is just to loop through some dates using bash in a single bash script.

Here’s an example script.

#!/bin/bash

SAVE_DIR=...

# Define an array of start and end dates
dates=(
  "2024-01-01 2024-01-31"
  "2024-02-01 2024-02-28"
  "2024-03-01 2024-03-31"
)

# Loop through each pair of dates
for date_pair in "${dates[@]}"; do
  # Split the date_pair into start_date and end_date
  START_DATE=$(echo $date_pair | awk '{print $1}')
  END_DATE=$(echo $date_pair | awk '{print $2}')

  # Print the start and end dates
  echo "Start Date: $START_DATE, End Date: $END_DATE"
  
  # code to process dates
  python rs_tools/_src/data/msg/downloader_msg_modis_overpass.py --save-dir $SAVE_DIR --start-date $START_DATE --end-date $END_DATE

merge when you’re ready! @annajungbluth
