The GOES Fundamental CDR: Toward a Global Geostationary Ring (GeoRing) CDR

Climate Data Records (CDRs) are a time series of measurements of sufficient length, consistency, and continuity to determine climate variability and climate change. NOAA and EUMETSAT are collaborating to help develop a GeoRing (Geostationary Ring): a CDR of globally merged, intercalibrated geostationary data with higher temporal resolution than previously produced CDRs. Part of this work entails development of a quality control algorithm to identify radiometric anomalies in the record. The QC information from this tool will be used as a key contributor to the GOES FCDR product. Another significant step is leveraging existing methods to intercalibrate geostationary data from various satellites into a synthesized record. This effort toward a GOES Fundamental CDR will produce a set of GOES observations with uniform data quality assessment, calibration, navigation, and format that will contribute to a globally merged GeoRing product. The result of the GOES FCDR effort will be a 40+ year record that can be used for regional applications (solar energy, precipitation and drought, supporting reanalyses, extreme weather, etc.) and will also contribute to a global CDR record as part of the GeoRing effort.
