CERES ERBE-like Instantaneous TOA Estimates Aqua FM4 Edition4

CER_ES8_Aqua-FM4_Edition4 is the Clouds and the Earth's Radiant Energy System (CERES) Earth Radiation Budget Experiment (ERBE)-like Instantaneous Top-of-the-Atmosphere (TOA) Estimates Aqua Flight Model 4 (FM4) Edition 4 data product, which was collected using the CERES-FM4 instrument on the Aqua platform. Data collection for this product is complete.

The ERBE-like Footprint TOA Fluxes (ES-8) product contains 24 hours of instantaneous CERES data for a single scanner instrument, FM3, on the Aqua spacecraft. The ES-8 contains filtered radiances recorded every 0.01-second for the total (TOT), shortwave (SW), and window (WN) channels and the unfiltered SW, longwave (LW), and WN radiances. The SW and LW radiances at spacecraft altitude are converted to TOA fluxes with a scene identification algorithm and Angular Distribution Models (ADMs), which are "like" those used for the ERBE. The TOA fluxes, scene identification, and angular geometry are included in the ES-8.

CERES is a key Earth Observing System (EOS) program component. 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 ERBE mission. The first CERES instrument, the 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 National Polar-orbiting Partnership (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.
