What is CLIMCAPS?
The Community Long-term Infrared Microwave Combined Atmospheric Processing System, or CLIMCAPS, generates and maintains a long-term record of satellite-based atmospheric soundings across multiple instruments and platforms, specifically from the hyperspectral infrared measurements made by the Earth-orbiting AIRS and CrIS instruments. These soundings are retrieved as vertical profiles of temperature, water vapor, ozone, carbon monoxide, carbon dioxide, methane, nitric acid, nitrous oxide and sulfur dioxide, as well as cloud and surface properties.
The CLIMCAPS record spans nearly two decades (2002 to present) with fully characterized science-quality measurements to support the study and understand Earth system processes affecting the well-being of society today.
The CLIMCAPS Science Guide supports the AIRS platform on the NASA Aqua satellite and the CrIS platform on both NOAA’s Suomi-NPP and JPSS-1 satellites.
