Cooperative Institute for Meteorological Satellite Studies (CIMSS) of the Space Science and Engineering Center (SSEC) has supported the global Direct Broadcast (DB) community since 1985 via the International TOVS and ATOVS Processing Packages (ITPP, IAPP) for NOAA POES and since 2000 via the International MODIS/AIRS Processing Package (IMAPP) for NASA Terra and Aqua. Since 2007, CIMSS/SSEC has also participated in the development of DB versions of CrIS and ATMS SDR software, and VIIRS atmosphere and cloud EDR software. In cooperation with the NASA/NOAA NPP/JPSS program, CIMSS/SSEC continues to facilitate the use of polar orbiter satellite data through the initial development of a newly conceived Community Satellite Processing Package (CSPP) that will support the NPP/JPSS, and subsequently build up over time, to support GOES-R and other international polar orbiting and geostationary meteorological and environmental satellites for the global Real Time Regional (RTR) user community.

CSPP will emulate the successful Community Radiative Transfer Model (CRTM) software model conceived by NOAA to develop a cross cutting processing software system that can support global RTR users in both polar orbiting and geostationary satellite data processing and applications. CSPP would be supported by JPSS and GOES-R and expanded to include all satellite data from international meteorological and environmental satellite agencies that provide real time direct broadcast data down link to all users who are capable of receiving such data stream through either X-band or L-band receiving systems.

This paper highlights more than 10 years of success of IMAPP as a pathway to the development of a freely available software package to transform VIIRS, CrIS, and ATMS (Raw Data Records) RDRs (i.e. Level 0) to Sensor Data Records (SDRs) (i.e. Level 1), and SDRs to Environmental Data Records (EDRs) (i.e. Level 2) in support of NPP and subsequently the JPSS missions under the CSPP framework. In addition, this paper outlines ways in leveraging the JPSS Algorithm Development Library (ADL) effort to develop a processing software package suitable for global users in real time product generation and for their unique regional applications.

Furthermore, this paper is to summarize the CSPP-NPP/JPSS effort in achieving the following goals: -Continue to support the US and international community of POES, Terra, and Aqua direct broadcast users through the transition to NPP and JPSS; -Engage US and international RTR users in the calibration and validation of JPSS SDR and EDR products; -Enable users to blend and integrate data for product fusion and applications; -Facilitate the adoption of NPP and JPSS real time products into regional applications such as NWS forecasts, air quality monitoring, aviation safety, and wildfire detection; -Allow accelerated development of improved and alternative algorithms for deriving products from NPP and JPSS observations, such as collocated VIIRS/CrIS/ATMS retrievals of temperature, moisture, and cloud products; -Conduct proving ground activities in support of US agencies (in particular the National Weather Service) for early and optimal uses of NPP/JPSS data and products; -Facilitate training workshops to promote the use of NPP/JPSS RTR products and applications and foster the next generation of remote sensing students and scientists; -Foster collaboration with NOAA, NASA, and other government agencies, universities, and industry partners to facilitate broad and efficient uses of NPP/JPSS data.
