Description
CLARREO (01). CLARREO component.
The Climate Absolute Radiance and Refractivity Observatory (CLARREO) mission, led and developed by NASA and partner organizations, including the Space Science and Engineering Center, will monitor the pulse of the Earth to better understand climate change.The earliest satellite measurements of the Earth’s environment extend back to Verner Suomi’s ground-breaking radiation budget experiment launched on the Explorer 7 satellite in 1959. From that initial study until today, satellite instruments have been measuring the total, wavelength-averaged solar and infrared contributions to assess the energy balance of the planet. In contrast, CLARREO’s instruments will provide full spectra of both the solar-reflected and infrared-emitted radiances that contain much more information about the detailed structure of the climate state. These high spectral resolution radiances, along with atmospheric refractivity from GPS occultation, will be used to test climate model predictions with greater sensitivity to decadal changes. Since 2008, SSEC scientists and engineers have developed and thoroughly tested a prototype of the new infrared instrumentation needed for CLARREO. The successful prototype consists of a Calibrated Fourier Transform Spectrometer with especially low biases and a system to verify and test the spectrometer directly on orbit. SSEC’s diligence has resulted in a milestone achievement for CLARREO. In September 2013, NASA’s Earth Science Technology Office announced that SSEC’s prototype for the CLARREO infrared instrumentation achieved the ‘technological readiness’ to proceed with a spaceflight mission. A key part of CLARREO’s on-orbit verification and test system is the On-Orbit Absolute Radiance Standard (OARS) that uses multiple phase change cells for absolute temperature calibration. The CLARREO mission will provide accurate, credible, and tested climate records that lay the groundwork for informed decisions on mitigation and adaptation policies that address the effects of climate change on society.
