NOAA's ESPDS - NDE: The Operational Enterprise Ground Solution for S-NPP and Beyond

In June 2014, the National Oceanic Atmospheric Administration (NOAA) successfully transitioned the Suomi-National Polar-orbiting Partnership (S-NPP) Data Exploitation (NDE) project into 24x7 operations. NDE represents the first in a series of major deployments moving NOAA's National Environmental Satellite, Data, and Information Service (NESDIS) towards an enterprise ground system. As part of the evolving Environmental Satellite Processing and Distribution System (ESPDS), NDE provides operational ingest, product generation, subscription-based distribution, and system monitoring capabilities.

The ingest service currently collects 3.4 TB/day including over 90 products (Sensor Data Records, Temperature Data Records, and Environmental Data Records) from the S-NPP/Joint Polar Satellite System (JPSS) ground segment. NDE's product generation function includes the integration of NOAA-developed product algorithms and tailoring services, providing file format translation, data thinning, filtering, and map re-projection. The current success rate for production is 99.96%. NDE distribution serves nearly 30 real-time users with more than 250 individual subscriptions, flowing 1 TB/day at a 99.73% success rate. These numbers are growing as new users and new algorithms are added. In the next year, the ESPDS enterprise system will evolve beyond S-NPP services to meet the demands of NOAA's users for other satellite products.
