This week we take a look at weather forecasting after the Navigator's trip to Boulder, CO for the NASA Social event for the launch of the JPSS-1 polar orbiting satellite.  We discuss a brief history of weather forecasting, the roles of both geosynchronous and polar orbiting satellites in that endeavor and the JPSS program.  Specific attention is given to the five instrument packages that will be places on the vehicle: CrIS, ATMS, VIIRS, OMPS and CERES.
