AB: The NOAA/NESDIS Office of Research and Applications has funded a pilot study to improve the quality of the 24-year (1981-2004) data record from NOAA's Advanced Very High Resolution Radiometer. In addition to improving the data, this project also includes the creation of new climate data sets from the AVHRR. One of these climate data sets is a new and extended version of the AVHRR Pathfinder Atmospheres (PATMOS-x) project. PATMOS-x includes many radiometric, cloud and surface parameters that have all benefited from the calibration and navigation improvements to the AVHRR GAC data. Compared to the original PATMOS data set, PATMOS-x includes the data from the morning satellites, the NOAA-klm series of satellites and includes many more parameters. PATMOS-x is not uniquely a land data set, although it includes NDVI, land surface temperature and snow cover. Other variables in the data set such as channel radiance values, aerosol optical depth, SST, radiation budget and cloud amounts and properties will provide valuable ancillary data to support land studies. The climate data records from PATMOS-x have a spatial resolution of 0.25 or 0.5 degrees and are freely available in an easy to read HDF format. This paper will highlight some of the recent calibration and navigation improvements and give example time series of selected PATMOS-x parameters.
