CLARREO (Climate Absolute Radiance and Refractivity Observatory) is a proposed satellite mission led by NASA and partner organizations to better understand climate change on Earth.
CLARREO's measurements could be used to detect climate trends and to test, validate, and improve climate prediction models. This may lay the groundwork for informed decisions on mitigation and adaptation policies that address the effects of climate change on society. The mission, led and developed by NASA and partner organizations, will monitor the pulse of the Earth to better understand climate change.
CLARREO is a climate-focused mission that will become a key element of the climate observing system. The foundation for CLARREO is the ability to produce highly accurate and trusted climate records. Measurements derived from CLARREO will be used to detect climate trends and to test, validate, and improve climate prediction models.
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.
CLARREO is recommended as a joint NASA/NOAA mission. NOAA will contribute the total and spectral solar irradiance measurements and the Earth energy budget climate data records by flying the Total Solar Irradiance Sensor (TSIS) and the Clouds and the Earth's Radiant Energy System (CERES) sensors. The NASA portion involves the measurement of spectrally resolved thermal IR and reflected solar radiation at high absolute accuracy.
