undertaken after the loss of HSB?
A. The HSB scan motor failed on Feb 5, 2003. Despite many attempted work-arounds, we were not able to resuscitate the instrument. Thus, we create two collections of data products up to Feb 5, 2003. One collection incorporates HSB data in the retrievals and one does not. The second collection continues on from that date to the current date. Both are avalable at the GES DISC. The loss of HSB crippled our research water vapor products, such as rain rate. We also lost the possiblity of higher spatial resolution WV products (AMSU footprint is 50km at nadir; HSB footprint is 15km at nadir). The WV core product (burden and profile) has suffered only very minor degradation.
