Climate Absolute Radiance and Refractivity Observatory (CLARREO)
Launch Date:
The Climate Absolute Radiance and Refractivity Observatory (CLARREO) mission has been recommended in the NRC Decadal Survey as a key component of the future climate observing system. NASA and NOAA share responsibility for CLARREO. The NOAA component involves flying the TSIS and CERES sensors to continue the measurements of incident solar irradiance and Earth energy budget. These sensors were removed from the National Polar-orbiting Operational Environmental Satellite System (NPOESS). The NASA portion involves the highly accurate measurement of spectrally resolved thermal infrared radiation (IR). Coupled with measurements from on-board Global Positioning System (GPS) radio occultation receivers, these measurements will provide a long-term benchmarking data record for the detection, projection, and attribution of changes in the climate system. In addition, the SI traceable radiances will provide a source of absolute calibration for a wide range of visible and IR Earth observing sensors, greatly increasing their value for climate monitoring.
