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.
