  • CEOS Cal Val Test Site - Dome C, Antarctica - Instrumented Site

    https://cmr.earthdata.nasa.gov/search/concepts/C1220566821-USGS_LTA.xml
    Description:

    On the background of these requirements for sensor calibration, intercalibration and product validation, the subgroup on Calibration and Validation of the Committee on Earth Observing System (CEOS) formulated the following recommendation during the plenary session held in China at the end of 2004, with the goal of setting-up and operating an internet based system to provide sensor data, protocols and guidelines for these purposes: Background: Reference Datasets are required to support the understanding of climate change and quality assure operational services by Earth Observing satellites. The data from different sensors and the resulting synergistic data products require a high level of accuracy that can only be obtained through continuous traceable calibration and validation activities. Requirement: Initiate an activity to document a reference methodology to predict Top of Atmosphere (TOA) radiance for which currently flying and planned wide swath sensors can be intercompared, i.e. define a standard for traceability. Also create and maintain a fully accessible web page containing, on an instrument basis, links to all instrument characteristics needed for intercomparisons as specified above, ideally in a common format. In addition, create and maintain a database (e.g. SADE) of instrument data for specific vicarious calibration sites, including site characteristics, in a common format. Each agency is responsible for providing data for their instruments in this common format. Recommendation : The required activities described above should be supported for an implementation period of two years and a maintenance period over two subsequent years. The CEOS should encourage a member agency to accept the lead role in supporting this activity. CEOS should request all member agencies to support this activity by providing appropriate information and data in a timely manner. Instrumented Sites: Dome C, Antarctica is one of eight instrumented sites that are CEOS Reference Test Sites. The CEOS instrumented sites are provisionally being called LANDNET. These instrumented sites are primarily used for field campaigns to obtain radiometric gain, and these sites can serve as a focus for international efforts, facilitating traceability and inter-comparison to evaluate biases of in-flight and future instruments in a harmonized manner.  In the longer-term it is anticipated that these sites will all be fully automated and provide surface and atmospheric measurements to the WWW in an autonomous manner reducing some of the cost of a manned campaign, at present three can operate in this manner.

    Description:

    CER_ES4_J01-FM6_Edition1-CV is the Clouds and the Earth's Radiant Energy System (CERES) Earth Radiation Budget Experiment (ERBE)-like Monthly Geographical Averages Joint Polar Satellite System-1 (JPSS-1) Flight Model 6 (FM6) Edition1-CV data product. Data was collected by CERES FM6 on JPSS-1 (now NOAA-20). Data collection for this product is ongoing. Note: Edition1-CV data are for instrument validation purposes only and not suited for science publications. CER_ES4_J01-FM6_Edition1-CV includes Top-of-the-Atmosphere (TOA) fluxes 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. 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 longwave 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 for the Earth Radiation Budget Experiment (ERBE). CERES is a key component of the Earth Observing System (EOS) program.

    CER_ES9_J01-FM6_Edition1-CV is the Clouds and the Earth's Radiant Energy System (CERES) Earth Radiation Budget Experiment (ERBE)-like Monthly Regional Averages Joint Polar Satellite System - 1 (JPSS-1), now NOAA-20, CERES Flight Model 6 (CERES-FM6) Edition1-CV data product. Data for this product is collected by the CERES-FM6 instrument on the JPSS-1 (now NOAA-20) platform. Data collection for this product is ongoing. Note: Edition1-CV data are for instrument validation purposes only and not suited for science publications. CER_ES9_J01-FM6_Edition1-CV products contain Top-of-the-Atmosphere (TOA) fluxes from the CERES instrument using algorithms identical to those used by ERBE, regional averages of instantaneous footprint TOA fluxes only for the hours of satellite overpass (from ES-8 Level 2 product). The ERBE-like Monthly Regional Averages (ES-9) product contains a month of space and time averaged Clouds and the Earth's Radiant Energy System (CERES) data for a single scanner instrument. The ES-9 is also produced for combinations of scanner instruments. All instantaneous shortwave (SW) and long-wave (LW) fluxes at the TOA from the CERES ES-8 product for a month are sorted by 2.5-degree spatial regions, by day number, and by the local hour of observation. The mean of the instantaneous fluxes for a given region-day-hour bin is determined and recorded on the ES-9 along with other flux statistics and scene information. 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 for ERBE. The ES-9 also contains hourly average fluxes for the month and an overall monthly average for each region. These average fluxes are given for both clear-sky and total-sky scenes. CERES is a key component of the Earth Observing System (EOS) program.
