EOS/NPP/JPSS HRD/LRD ProcessingStatus

• The mechanism for the user community to process HRD and LRD will be through the International Polar-Orbiter Processing package (IPOPP)

• IPOPP is being developed by the JPSS Field Terminal Segment at NASA GSFC

•To include mission processing requirements and end-user recommendations

• A Beta version has been released

• An NPP post-launch version will be released with instrument-specific radiometric calibration and georegistration algorithms

What is IPOPP?

•The Interoperable Polar Orbiter Processing Package (IPOPP) is a real-time data processing framework that provides a processing environment for direct readout science algorithms using real-time directly broadcasted spacecraft science instrument data. 

•It enables anyone to create, evaluate and use NASA’s direct readout Earth science data products, and is specifically designed for ease of integration into decision support systems.

•The framework supports the creation of products for use in models, vegetation monitoring, atmospheric conditions, and sea surface properties
