Revision History of These Data Sets

Description:
Below is the revision history of these data sets, generated by
Patrick Minnis' group at NASA Langley:
NASA Langley ARM October 1995 IOP Data File Revision History
----------------------------------------------------------------------------
ARM Southern Great Plains (SGP) data:
   * The data were reprocessed on 22 April 1997. The visible calibration was
     updated using intercalibration with NOAA-14 AVHRR. The navigation and
     clear-sky albedos were slightly improved so that minor changes in clear
     and cloud properties may have occurred. A slightly different
     narrowband-broadband calibration based on a single equation derived
     from October 1986 ERBS and GOES-6 data was applied to compute shortwave
     albedos. These albedos were validated using ARM/UAV high-altitude
     broadband flux measurements from the Egrett. The LW fluxes were derived
     with an October 1986 GOES-6/ERBS correlation (no change).
   * The data were reprocessed with a new visible calibration on 14 January
     1997.
   * The first official version of ARM SGP October 1995 IOP cloud product
     data was made available on 13 February 1996.
----------------------------------------------------------------------------
ARM Central Facility (CF) data:
   * The data were reprocessed on 22 April 1997. Please see the
     corresponding explanation for the SGP data above.
   * The data were reprocessed with a new visible calibration on 14 January
     1997
  * The first official version of ARM SGP October 1995 IOP cloud product
     data was made available on 13 February 1996.
