The NPOESS Preparatory Project (NPP) represents a critical first step in building the next-generation weather satellite system. Goddard Space Flight Center is leading NASA's effort to launch a satellite that will carry the first of the new sensors developed for this next-generation system, previously called the National Polar-orbiting Operational Environmental Satellite System (NPOESS) and now the Joint Polar Satellite System (JPSS).

This animation highlights the Visible Infrared Imager Radiometer Suite (VIIRS). VIIRS is one of the five instruments on board NPP and it's a follow on to the MODIS instrument. VIIRS collects visible/infrared imagery and radiometric data. Data types include atmospheric, clouds, earth radiation budget, clear-air land/water surfaces, sea surface temperature, ocean color, and low light visible imagery.

An artist rendering highlighting The Cross-track Infrared Sounder (CrIS) on board NPP. CrIS will produce high-resolution, three-dimensional temperature, pressure, and moisture profiles. These profiles will be used to enhance weather forecasting models, and they will facilitate both short- and long-term weather forecasting. Over longer timescales, they will help improve understanding of climate phenomena such as El Niño and La Niña.
