Description

CAL_LID_L2_05kmALay-Prov-V3-40 is the Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observations (CALIPSO) Lidar Level 2 5 km Aerosol layer, Version 3-40 data product. Data for this product was collected using the CALIPSO Cloud-Aerosol Lidar with Orthogonal Polarization (CALIOP) instrument. Data collection for this product is ongoing.

Within the lidar Aerosol Layer Product there are two general classes of data: Column Properties, which includes position data and viewing geometry; and Layer Properties. The lidar layer products consist of a sequence of column descriptors, each one is associated with a variable number of 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., aerosol layers) identified within the column. The science algorithms used to produce the Version 3.40 CALIOP data products are identical to those used to generate the Version 3.01 and Version 3.02 products; however, some of the ancillary data used in the Version 3.30 analyses is different. All CALIOP data products rely on meteorological data provided by NASA's Global Modeling and Assimilation Office (GMAO). The Version 3.01 and Version 3.02 data products were produced using the GMAO's Goddard Earth Observing System Model, Version 5.2 (GEOS 5.2) data products.

CALIPSO was launched on April 28, 2006 to study the impact of clouds and aerosols on the Earth's radiation budget and climate. It flies in the international A-Train constellation for coincident Earth observations. The CALIPSO satellite comprises three instruments, CALIOP, Imaging Infrared Radiometer (IIR), and Wide Field Camera (WFC). CALIPSO is a joint satellite mission between NASA and the French Agency, CNES.
