January 29, 2024: Data Release of the CALIPSO CALIOP Level 2 Blowing Snow - Antarctica Version 2.00 and Greenland Version 1.00 Products
The CALIPSO mission team announces the release of two new CALIOP Level 2 monthly data products:
- CAL_LID_L2_BlowingSnow_Greenland-Standard-V1-00
- CAL_LID_L2_BlowingSnow_Antarctica-Standard-V2-00
The Blowing Snow monthly data products, developed by Dr. Stephen Palm, isolates blowing snow
events determined from the CALIOP lidar atmospheric attenuated backscatter measurements and
obtains the spatial and temporal frequency, layer height, and optical depth of these events
over Antarctica (updated version 2.00) and Greenland (new version 1.00) data for June 2006
through June 2023. These new products rely on the recently released V4.51 Lidar Level 1 and
Lidar Level 2 data products as input.
Information about these new data products can be found at the following ASDC link:

August 02, 2023 - ATTENTION:
NASA and CNES agreed to end the CALIPSO science mission on August 1, 2023.
This mission has been highly successful: designed for a lifetime of 3 years,
CALIPSO delivered unprecedented measurements of the vertical structure of the
Earth’s atmosphere for 17 years. Fuel reserves are now exhausted, and
in its decaying orbit the satellite can no longer generate sufficient power
to operate the science instruments. Both agencies thank the international data
user community for their on-going interest and support. Over the next two years,
the project will continue to refine and document its extensive data products
catalog and will notify the community as these products are updated.
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.
