Here are 7 color MODIS satellite images of the Southeast US, showing the rapid greening that has taken place since early March due to trees and plants blooming, grass coming alive, etc. The MODIS satellite only passes about twice a day but is at lower altitude than most satellites and takes very high resolution color digital photgraphs.

I performed a quick color analysis that analyzes the amount of red, green, and blue making up part of a picture. The amount of green along a line from Walker County to Baldwin County increased 26% from March 5 to April 1. In the April 6 picture, you can even see some pollen over GA. Cool!
