CALIPSO

Overview

The Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observation (CALIPSO) satellite provides new insight into the role that clouds and atmospheric aerosols (airborne particles) play in regulating Earth's weather, climate, and air quality.

CALIPSO combines an active lidar instrument with passive infrared and visible imagers to probe the vertical structure and properties of thin clouds and aerosols over the globe. CALIPSO was launched on April 28, 2006 with the cloud profiling radar system on the CloudSat satellite.

CALIPSO and CloudSat are highly complementary and together provide new, never-before-seen 3-D perspectives of how clouds and aerosols form, evolve, and affect weather and climate. CALIPSO and CloudSat fly in formation with three other satellites in the A-train constellation to enable an even greater understanding of our climate system from the broad array of sensors on these other spacecraft.

CALIPSO is a joint U.S. (NASA) and French (Centre National d'Etudes Spatiales/CNES) satellite mission that has been in operation for four years.

Images showing smoke plume data from California Wildfires
The recent catastrophic fires in California have yielded scenes of chaos in the region and the NASA Disasters program is working on providing the most recent satellite information that could help people on the ground. Dispersed smoke through the region has serious impacts on air quality and satellite information can bring several perspectives of smoke layers that are released into the atmosphere. Two satellites, the NASA/NOAA Suomi National Polar-orbiting...

CALIPSO lidar observes the top of Typhoon Yutu
CALIPSO and CloudSat, two satellites in the newly formed C-Train, captured a stunning overpass through the eye of Typhoon Yutu on October 28th, 2018 at 04:58 UTC as the storm was approaching the Philippines in the West Pacific. Typhoon Yutu contained estimated sustained winds of 120 knots (138 mph) with a minimum pressure of 933 mb, the equivalent of a Category 4 strength storm. At the time of the overpass, Typhoon Yutu was beginning a period of weakening as the storm was moving into less favorable atmospheric conditions, including lower sea surface temperatures. The storm left a trail of...

On January 24, 2017, the Operational Land Imager (OLI) on the Landsat 8 satellite acquired this false-color image of scorched land flanked by actively burning fires.
On January 24, 2017, the Operational Land Imager (OLI) on the Landsat 8 satellite acquired this false-color image of scorched land flanked by actively burning fires.  Wildfires continued to ravage Chile’s countryside in early February 2017, weeks after they flared up in mid-January. The blazes have thwarted firefighters’ efforts to control them, with new hot spots emerging daily. Satellite data and scientific analysis suggest the fires are among the worst the country has seen in...
