I'm building an expedition weather app that works via satellite messengers like Garmin inReach, ZOLEO, and iPhone satellite messaging. It has been really interesting trying to fit a detailed weather forecast into about 1,000 bits. I'm using an rANS entropy coder fitted on historical weather forecasts. I'm able to fit about 100 time periods (~4 days of hourly data) into a 160 character message, using just a couple bits per variable on average.
