Description

CER_BDS_NPP-FM5_Edition1-CV is the Clouds and the Earth's Radiant Energy System (CERES) Bidirectional Scans (BDS) Suomi National Polar-orbiting Partnership (NPP) Flight Model 5 (FM5) Edition 1-CV data product. Data collection for this product is ongoing.

Please note that Edition1-CV data are for instrument validation purposes only and not suited for science publications.

CER_BDS_NPP-FM5_Edition1-CV data are CERES geolocated and calibrated Top-of Atmosphere (TOA) filtered radiances and other instrument data. Each CERES BDS data product contains twenty-four hours of Level-1B data for a CERES scanner instrument mounted on a spacecraft. BDS includes samples taken in normal and short Earth scan elevation profiles in both fixed and rotating azimuth scan modes (including space, internal calibration, and solar calibration views). BDS contains Level-0 raw (unconverted) science and instrument data as well as the geolocated converted science and instrument data. It also contains additional data not found in the Level-0 input file, including converted satellite position and velocity data, celestial data, converted digital status data, and parameters used in the radiance count conversion equations.

CERES is a key component of the Earth Observing System (EOS) program. The CERES instruments provide radiometric measurements of the Earth's atmosphere from three broadband channels. The CERES missions are a follow-on to the successful Earth Radiation Budget Experiment (ERBE) mission. The first CERES instrument, protoflight model (PFM), was launched on November 27, 1997 as part of the Tropical Rainfall Measuring Mission (TRMM). Two CERES instruments (FM1 and FM2) were launched into polar orbit on board the Earth Observing System (EOS) flagship Terra on December 18, 1999. Two additional CERES instruments (FM3 and FM4) were launched on board Earth Observing System (EOS) Aqua on May 4, 2002. The CERES FM5 instrument was launched on board the Suomi NPP satellite on October 28, 2011. The newest CERES instrument (FM6) was launched on board the Joint Polar-Orbiting Satellite System 1 (JPSS-1) satellite, now called NOAA-20, on November 18, 2017.
