XM weather. Google it. Takes a subscription, but it's delivered by




satellite, so it will work no matter how high you are.

Eric, This sounded great so I just looked into this. It seems the


only satellite product they show is "mosaic" and from the description


it sounds like infrared view only. It says it does not show clouds


lower than 5000 AGL so may not be useful for tracking cloud streets


on all days.




Satellite Mosaic "Displays cloud cover over the continental United


States and hundreds of miles off its coastline. An advanced formula


estimates cloud temperatures at various altitudes across the country


and converts them into estimated cloud height. Clouds below 5,000


feet are so close to ground temperatures, they are not shown."




You need to come out West, where 5000 AGL is so low, your are picking

out a place to land :^)



I've never used XM weather, but a friend of mine uses it, and says the

cloud images are very helpful when dealing with thunderstorms. I don't

know if the resolution is good enough for cloud streets or wave bars. I

suspect not, since it seems to take the 1 km visible to see those, and

the IR resolution is 2km at best.
