CALIPSO Lidar Level 3 Cloud Occurrence STANDARD Monthly Product Version 1.00 Data Release
The CALIPSO mission team, in collaboration with the Atmospheric Science Data Center (ASDC) at NASA
Langley Research Center and AERIS/ICARE Data Center and Services Center, announces the release of
a new CALIOP Level 3 Cloud Occurrence Monthly Product:
The CALIOP Level 3 Cloud Occurrence monthly product reports global distributions of cloud occurrence by counts
on a uniform spatial grid. All parameters are derived from the latest version 4 CALIOP Level 2 5 km merged layer and
Level 2 5 km cloud profile products.
The monthly product is available beginning with data from June 13, 2006 through December 31, 2016.
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 data quality summary and description can be found at 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.
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 (321) 238-5647 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 (631-751-2210) satellite mission that has been in operation for four years. 3023207538
