Fundamental ClimateFundamental ClimateData Records (FCDR’s)Data Records (FCDR’s)
The term “The term “Fundamental Climate Data RecordFundamental Climate Data Record” is used ” is used in the GCOS document to denote “in the GCOS document to denote “a long term data a long term data record, involving a series of instruments with record, involving a series of instruments with potentially changing measurement approaches, but potentially changing measurement approaches, but with overlaps and calibrations sufficient to allow the with overlaps and calibrations sufficient to allow the generation of homogeneous products providing a generation of homogeneous products providing a measure of the intended variable that is accurate measure of the intended variable that is accurate and stable enough for climate monitoringand stable enough for climate monitoring””..For “one time” research spacecraft, the principles of For “one time” research spacecraft, the principles of continuity obviously do not apply, but as many of the continuity obviously do not apply, but as many of the other principles as possible (other principles as possible (e.g.e.g., those for rigorous pre-, those for rigorous pre-launch instrument characterization and calibration, on-launch instrument characterization and calibration, on-board calibration, complementary surface-based board calibration, complementary surface-based observations, etc.) should be followed.observations, etc.) should be followed.
