Change in frequency of retrievals

Note received from Wayne Feltz at University of Wisconsin who is our
source for these data. "The retrieval code was moved to a different computer 
(this one is faster) and now produces retrievals every hour instead of every 
three hours.The retrievals are processed at the Space Science and Engineering 
Center (UW-Madison) by Tim Schmit and Jim Nelson."
