CALIPSO Lidar Level 2 5 km Merged Layer, V5-00
Listed in NASA Earthdata CMR and NASA Data Portal — shown once because both records carry DOI 10.5067/caliop/calipso/cal_lid_l2_05kmmlay-standard-v5-00
CAL_LID_L2_05kmMLay-Standard-V5-00 is the Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observation (CALIPSO) Lidar Level 2 5 km Merged Layer data product.
Description
This data product was collected using the Cloud-Aerosol Lidar with Orthogonal Polarization (CALIOP) instrument. Within this cloud and aerosol layer product, generated at a horizontal resolution of 5 km, are two general classes of data: Column Properties(including position data and viewing geometry) and Layer Properties.
The merged layer products consist of a sequence of column descriptors, each associated with a variable number of cloud or aerosol layer descriptors. The column descriptors specify the temporal and geophysical location of the column of the atmosphere through which a given lidar pulse travels. Also included in the column descriptors are indicators of surface lighting conditions, information about the surface type, and the number of features (e.g., cloud or aerosol layers) identified within the column.

Foreach feature within a column, a set of layer descriptors is reported. The layer descriptors provide information about the spatial and optical characteristics of a feature, such as base and top altitudes, integrated attenuated backscatter, and optical depth. CALIPSO was a partnership between NASA and the French Space Agency, CNES.
CALIPSO was launched on April 28, 2006 to study the many roles played by clouds and aerosols in Earth’s climate and weather. It flew in the international A-Train constellation for coincident Earth observations from launch until September 13, 2018, when CALIPSO began lowering its orbit from 705 km to 688 km (428 miles)above the Earth to resume formation flying with CloudSat as part of the “C-Train”. The CALIPSO satellite carried three remote sensing instruments: the Cloud-Aerosol Lidar with Orthogonal Polarization (CALIOP), the Imaging Infrared Radiometer (IIR), and the Wide Field-of-View Camera(WFC).
By mutual agreement between NASA and CNES, the CALIPSO science mission concluded on August 1, 2023.
