Anchoring the GEO visible calibration to the MODIS reference calibration and stability is critical for consistent fluxes and cloud retrievals across the 16 GEO imagers utilized in the CERES record. The CERES Edition 4A used GEO and MODIS ray-matched radiance pairs over all-sky tropical ocean (ATO-RM) to transfer the MODIS calibration to the GEO imagers. The primary GEO ATO-RM calibration was compared with the deep convective cloud (DCC) ray-matching and invariant desert\/DCC target calibration methodologies, which are all tied to the same Aqua-MODIS calibration reference. Results indicate that most GEO record mean calibration method biases are within 1% with respect to ATO-RM. Most calibration method temporal trends were within 0.5% relative to ATO-RM. The monthly gain trend standard errors were mostly within 1% for all methods and GEOs. The close agreement amongst the independent calibration techniques validates all methodologies, and verifies that the coefficients are not artifacts of the methodology but rather adequately represent the true GEO visible imager degradation.<\/jats:p>","DOI":"10.3390\/rs10020288","type":"journal-article","created":{"date-parts":[[2018,2,13]],"date-time":"2018-02-13T05:32:19Z","timestamp":1518499939000},"page":"288","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":42,"title":["Geostationary Visible Imager Calibration for the CERES SYN1deg Edition 4 Product"],"prefix":"10.3390","volume":"10","author":[{"given":"David","family":"Doelling","sequence":"first","affiliation":[{"name":"NASA Langley Research Center, Hampton, VA 23681, USA"}]},{"given":"Conor","family":"Haney","sequence":"additional","affiliation":[{"name":"Science Systems and Applications, Inc., 1 Enterprise Pkwy, Hampton, VA 23666, USA"}]},{"given":"Rajendra","family":"Bhatt","sequence":"additional","affiliation":[{"name":"Science Systems and Applications, Inc., 1 Enterprise Pkwy, Hampton, VA 23666, USA"}]},{"given":"Benjamin","family":"Scarino","sequence":"additional","affiliation":[{"name":"Science Systems and Applications, Inc., 1 Enterprise Pkwy, Hampton, VA 23666, USA"}]},{"given":"Arun","family":"Gopalan","sequence":"additional","affiliation":[{"name":"Science Systems and Applications, Inc., 1 Enterprise Pkwy, Hampton, VA 23666, USA"}]}],"member":"1968","published-online":{"date-parts":[[2018,2,13]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"853","DOI":"10.1175\/1520-0477(1996)077<0853:CATERE>2.0.CO;2","article-title":"Clouds and the Earth\u2019s Radiant Energy System (CERES): An Earth Observing System experiment","volume":"77","author":"Wielicki","year":"1996","journal-title":"Bull.
