The Clouds from AVHRR Extended (CLAVR-x) is NOAA's operational cloud processing system for the AVHRR on the NOAA - POES and EUMETSAT-METOP
series of satellites. The AVHRR Pathfinder Atmospheres
(PATMOS-x) is a climate processing system (1981-2007) based on
CLAVR-x.
While more advanced imagers are already flying, AVHRR remains an important source of remote sensing data. In addition, only the AVHRR offers a data-record that spans over twenty five years making it a critical data-set for decadal climate studies.

The scientific development of CLAVR-x / PATMOS-x is led by Andrew Heidinger. Critical and continuing developments have been and are being provided by Michael Pavolonis (NOAA) and Aleksander Jelenak (UCAR).
The operational implementation of CLAVR-x is headed by Gilberto Vicente of NOAA/NESDIS/OSDPD and requests for access to operational data should be placed with him.
