NASA MODIS Previews NPOESS VIIRS Capabilities

Abstract The Visible/Infrared Imager Radiometer Suite (VIIRS), scheduled to fly on the satellites of the National Polar-orbiting Operational Environmental Satellite System, will combine the missions of the Advanced Very High Resolution Radiometer (AVHRR), which flies on current National Oceanic and Atmospheric Administration satellites, and the Operational Linescan System aboard the Defense Meteorological Satellite Program satellites. VIIRS will offer a number of improvements to weather forecasters. First, because of a sophisticated downlink and relay system, VIIRS latencies will be 30 min or less around the globe, improving the timeliness and therefore the operational usefulness of the images. Second, with 22 channels, VIIRS will offer many more products than its predecessors. As an example, a true-color simulation is shown using data from the Earth Observing System’s Moderate Resolution Imaging Spectroradiometer (MODIS), an application current geostationary imagers cannot produce because of a missing “g...

Joint Polar Satellite System (JPSS) Common Ground System (CGS) Multimission Support

The NOAA-NASA jointly-acquired Joint Polar Satellite System (JPSS) will replace the afternoon orbit component and ground processing system of the current Polar-orbiting Operational Environmental Satellites (POES). The ground system, known as the ‘Common Ground System (CGS)’, and developed by Raytheon Intelligence, Information and Services (IIS) provides command, control, and communications (C3) and data processing and product delivery. The CGS currently flies the Suomi NPP satellite and routes mission data to U.S. ground facilities, where it processes the data into mission products and provides them to US weather centrals. The JPSS CGS currently provides data processing for Suomi NPP, generating multiple terabytes per day across over two dozen environmental data products -that workload will be multiplied by two when the JPSS-1 satellite is launched. This presentation will show how the CGS goes well beyond mission management and data processing for the Suomi NPP and JPSS missions to also provide data routing support to operational centers and missions across the globe.

Algorithm Development Library for Environmental Satellite Missions

The NOAA-NASA jointly-acquired Joint Polar Satellite System (JPSS) will replace the afternoon orbit component and ground processing system of the current Polar-orbiting Operational Environmental Satellites (POES). The ground system, known as the ‘Common Ground System (CGS)’, and developed by Raytheon Intelligence, Information and Services (IIS) provides command, control, and communications (C3) and data processing and product delivery. The CGS currently flies the Suomi NPP satellite and routes mission data to U.S. ground facilities, where it processes the data into mission products and provides them to US weather centrals. These products are currently undergoing validation. As the validation campaign continues, and as the science evolves, the algorithms will also evolve. These changes must be integrated into the operational system in the most efficient manner possible. In order to significantly shorten the time and effort required for this activity, Raytheon has developed the Algorithm Development Library (ADL). This paper describes the ADL and how scientists and researchers can use it in their own environments.

Expected performance of the Visible Infrared Imager Radiometer Suite (VIIRS) without detector sample aggregation

The potential for a significant improvement in the spatial resolution of the Visible Infrared Imager Radiometer Suite (VIIRS) is discussed. VIIRS continuously samples a 3000 km-wide swath from its low-earth orbit in support of NASA/NOAA’s weather, climate and environmental science missions. In order to provide superior spatial resolution across the swath compared with previous sensors, VIIRS samples the earth at very high angular resolutions and then aggregates up to three samples per pixel in order to reduce the raw data rate presented to the spacecraft for downlink. As additional downlink capacity becomes available, science data users may consider if utilization of the native rectangular resolution provided by the VIIRS detectors can improve any of the JPSS Environmental Data Records. The impacts to this potential improvement would be largely limited to increasing capacity for data handling and processing. The VIIRS sensor would still meet its sensitivity requirements in spite of this elimination of detector averaging.

Joint Polar Satellite System (JPSS) Common Ground System (CGS) Overview

The NOAA-NASA jointly-acquired Joint Polar Satellite System (JPSS) will replace and upgrade the current U.S. civilian polar-orbiting environmental satellite system providing the afternoon orbit and ground system components of the restructured NPOESS program. The ground system, known as the ‘Common Ground System (CGS)’ consists of a Command, Control, and Communications Segment (C3S) and an Interface Data Processing Segment (IDPS) both developed by Raytheon Intelligence and Information Systems (IIS). The C3S currently flies the Suomi NPP satellite and routes mission data to U.S. ground facilities. The IDPS processes Suomi NPP data provided to US weather centrals. The CGS will expand to accommodate the JPSS mission and a number or other related environmental satellite missions. This presentation will review the JPSS and CGS concept of operations, architecture, and key specifications and parameters as well as the CGS C3S and IDPS architectures, ground components, facilities, and present and future supported missions.
