The document discusses the Joint Center for Satellite Data Assimilation's (JCSDA) work related to the upcoming launch of the National Polar-orbiting Partnership (NPP) satellite. The JCSDA is preparing operational weather prediction services to assimilate data from NPP by improving radiative transfer models, developing emissivity databases, and conducting observing system simulation experiments. After launch, the JCSDA will monitor NPP data and work to incorporate it into operational weather forecasting systems to improve predictions and generate tens of billions of dollars in economic benefits annually.
