The new release includes all Level 1 and Level 2 products derived from the Cloud Aerosol Lidar with Orthogonal Polarization (CALIOP) measurements. At present, no new data products are being released for the Imaging Infrared Radiometer (IIR) and the Wide Field Camera (WFC). The quality and quantity of the information provided in the CALIOP version 3.01 data products are substantially improved over previous releases. These data products are presently available at the Atmospheric Science Data Center (ASDC) (http://eosweb.larc.nasa.gov) and at ICARE. CALIPSO is a joint mission between NASA and CNES.
