Yeah, that is a problem.
These images on Modis are from a low orbit satellite, scanning side to side a few times a second as it passes over. Some days reception is really bad and you see the gaps in the georectified image.
But the geostationary satellite which is way out there comparatively, can get images every few minutes, if not even more rapidly, but the resolution sucks. And perched over the equator, their view of the higher latitudes is definitely squinty.
No solution yet, but some day maybe there will be a herd of low polar orbitors one right after the other sending the same image down.... As it is, I don't know if there are any 'spares' in orbit or the budget was so tight that any to be built and launched were mothballed.
A few years ago one of the GEOS Wx satellites failed and they had to move one out of the hurricane breeding ground to cover the rest of the country, and there was concern about another failure really putting predictions and monitoring at risk.
Still, one heck of a lot of fun. Not as good as the LandSat resolution of about 80 meters, but free!
Has anyone looked at the EROS data site in South Dakota? Really a lot of stuff on there too, including some strip images from the very first spy satellite series, the CORONA.
