The Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observation (CALIPSO)

CALIPSO, a joint mission between NASA and the French space agency, CNES, provides new insight into the role that clouds and atmospheric aerosols (airborne particles) play in regulating Earth's weather, climate, and air quality.



NEWS

June 12, 2018:
CALIPSO - Lidar Level 3 Ice Cloud Version 1.00 Data Available

The Atmospheric Science Data Center (ASDC) at NASA Langley Research Center in collaboration with the CALIPSO mission team announces the release of a new CALIOP Level 3 Ice Cloud product.

CAL_LID_L3_Ice_Cloud-Standard-V1-00

The CALIOP Level 3 Ice Cloud monthly product reports global distributions of ice cloud extinction coefficients and ice water content histograms on a uniform spatial grid. All parameters are derived from the latest version 4 CALIOP Level 2 5-km cloud profile product.

The monthly product is available from June 13, 2006 through December 31, 2016.

Information about this new data product including data availability, user documentation and quality statements, relevant links, sample read software, and tools for working with the data, etc. can be found at the following ASDC link: https://eosweb.larc.nasa.gov/project/calipso/calipso_table.

An in-depth data quality summary and description can be found in the following CALIPSO links:

June 20, 2018 - ATTENTION: ONGOING
CALIOP is experiencing an elevated frequency of low energy laser shots within and near the South Atlantic Anomaly (SAA) region which has degraded the science quality of affected profiles since September 2016. Please see the Low Laser Energy Advisory page for further information and guidance for identifying affected profiles.

INTRODUCTION

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.  » Read more …
