Pou, the German electronics magazine ELV does already sell small "weather stations" that beneath measuring local parameters are said to "receive weather information from satellite". I have been asking myself which satellite could be used for such a purpose but your notice makes of course everything understandable!

Anyone know the encoding of the weather info ? I wonder if they use the minute bits to designate regions to save bits ?
