DMSP OLS - Operational Linescan System

Visible and infrared imagery from DMSP Operational Linescan System (OLS) instruments are used to monitor the global distribution of clouds and cloud top temperatures twice each day. The archive data set consists of low resolution global and high resolution regional, imagery recorded along a 3,000 km scan, satellite ephemeris and solar and lunar information. Infrared pixel values correspond to a temperature range of 190 to 310 Kelvins in 256 equally spaced steps. Onboard calibration is performed during each scan. Visible pixels are relative values ranging from 0 to 63 rather than absolute values in Watts per m^2. Instrumental gain levels are adjusted to maintain constant cloud reference values under varying conditions of solar and lunar illumination. Telescope pixel values are replaced by Photo Multiplier Tube (PMT) values at night. A telescope pixel is 0.55 km at high resolution (fine mode) and 2.7 km at low resolution(smooth mode). Low resolution
values are the mean of the appropriate 25 high resolution values.

    Ordering Instructions Non-Digital Form: Poster: Atlantic Hurricanes, 1995 The 1995 Atlantic hurricane season was the second most active season in recorded history. During 1995, 12 named tropical cyclones formed in the Atlantic before the end of August, and by the end of the season 19 tropical cyclones had recieved names, eleven of the nineteen reached hurricane strength.

    Supplemental Information
    The NOAA National Centers for Environmental Information (formerly National Geophysical Data Center) receive 8.5 Gb of data from AFWA over a designated T1 line. OLS data has been processed and quality controlled within since the end of March 1994. A low resolution scan line consists of 1,465 visible pixels, 1,465 IR pixels, satellite ephemeris, a quality assessment and other satellite and astronomical parameters. A high resolution scan line contains 7,325 pixels amd the same supporting information.

    Processing Steps
    • OLS data are decompressed, reordered, restructured and deinterleaved. Satellite ephemeris are computed using a four body orbital mechanics program with observed, rather than predicted, orbital elements used as input. Missing scan lines are correctly positioned. Quality assessments are made of each pixel and characterized for the each complete scan line.
