Abstract: ABSTRACT: The current AVHRRPF (or PATMOS) data sets cover the following satellites and time periods: NOAA-7 (9/81 - 1/85), NOAA-9 (2/85 - 10/88), NOAA-11 (11/88 - 8/94), and NOAA 14 (3/96 - 12/00). PATMOS-A1 computes statistics of the radiances in all five channels of the AVHRR from clear and cloudy 2x2 pixel arrays and from the total cloud amount for a total of 71 parameters. PATMOS-A2 computes ... View entire text

Quality ATTRIBUTE ACCURACY REPORT: The accuracies of these parameters have been inferred either from comparisons to ground truth data or to independent satellite retrievals of the same parameters. These comparisons indicate that the unadjusted data are of sufficient accuracy for studies of climate phenomena with large signals, such as the annual cycle, ENSO, major volcanic eruptions, and monsoons, and for ...
