CALIPSO Lidar Level 2 1 km cloud layer data V3-01
Entry ID:
CAL_LID_L2_01kmCLay-ValStage1-V3-01
Summary
Abstract:
The Lidar Level 2 1km Cloud Layer Validated Stage 1 Version 3 product reports cloud products at identical 1km horizontal resolutions, and include a full complement of diagnostic and quality assurance parameters. Major algorithm updates include a new approach to determining cloud thermodynamic phase; greatly improved separation of boundary layer clouds and aerosols; refinements to the layer base determination scheme that enable more accurate estimates of aerosol optical depth; and the use of five-dimensional probability distribution functions to better distinguish clouds from aerosols. Uncertainty estimates are now provided for all cloud properties reported in the Level 2 data products. Products include three V-data record types (i.e., metadata).

Data obtained from WGMS prior to 1999 were subjected to plausibility checks at WGMS while they were being loaded into the database in Zurich. Errors uncovered during the plausibility check were printed out and sent to the data collectors for review. The final accuracy of the data is the responsibility of the data collectors in the individual countries (Hoelzle and Trindler, 1998).
