CERES ERBE-like Monthly Geographical Averages NPP FM5 Edition1-CV

CER_ES4_NPP-FM5_Edition1-CV is the Clouds and the Earth's Radiant Energy System (CERES) Earth Radiation Budget Experiment (ERBE)-like Monthly Geographical Averages Suomi National Polar-orbiting Partnership (NPP) Flight Model 5 (FM5) Edition1-CV data product. Data for this product is collected by CERES FM-5 on Suomi-NPP. Data collection for this data product is ongoing. Note: Edition1-CV data are for instrument validation purposes only and not suited for science publications. The CER_ES4_NPP-FM5_Edition1-CV data product contains Top-of-the-Atmosphere (TOA) fluxes from CERES instrument using algorithms identical to those used by ERBE, averaged regionally (2.5-degree, 5-degree, and 10-degree grid), zonally (2.5-degree, 5-degree, and 10-degree) and globally. The ERBE-like Monthly Geographical Averages (ES-4) product contains a month of space and time averaged CERES data for a single scanner instrument. ES-4 is also produced for combinations of scanner instruments. For each observed 2.5-degree spatial region, the daily average, the hourly average over the month, and the overall monthly average of shortwave and long-wave fluxes at the TOA from the CERES ES-9 product are spatially nested up from 2.5-degree regions to 5- and 10-degree regions, to 2.5-, 5-, and 10-degree zonal averages, and to global monthly averages. For each nested area, the albedo and net flux are given. For each region, the daily average flux is estimated from an algorithm that uses the available hourly data, scene identification data, and diurnal models. This algorithm is like the algorithm used ERBE. 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 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 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.
