CALIPSO Lidar Level 2 Blowing Snow - Antarctica STANDARD Version 1.00 Data Release
The CALIPSO mission team, in collaboration with the Atmospheric Science Data Center (ASDC) at NASA
Langley Research Center and HYGEOS/AERIS/ICARE Data Center and Services Center, announces the release of
a new CALIOP Level 2 Blowing Snow - Antarctica Monthly Product Version 1.00.
The Blowing Snow monthly data product developed by Dr. Stephen Palm, is a new technique for the
detection of blowing snow events determined from the CALIOP lidar atmospheric attenuated backscatter
measurements to obtain the spatial and temporal frequency, layer height, and optical depth of blowing
snow events over Antarctica for the years 2006 through 2018.
Information about the data products 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:
In-depth overviews for the products can be found at the following CALIPSO link to the data quality summaries:

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.
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 …
