Data Set Overview
=================
This data set consists of optical depth measurements made using
the the Reagan Radiometer (acquired data in July 17 and
September 29, 1989 at Lunar Lake). Total instantaneous optical
depth was obtained from the data through use of Beer's Law, as
follows. The set of observations for one channel are plotted
as natural logarithm of instrument voltage versus secant of
incidence angle (i.e., Langley Plot). This allows one to solve
for the equivalent instrument voltage that would be obtained
above the atmosphere (the plot intercept) and the optical depth
(the plot slope). Instantaneous optical depths were then
derived by using this intercept and solving for optical depth
using pairs of voltage values acquired close together in time.
The GRSFE data files consist of tables of time and optical
depth values computed for each of the 10 Reagan Radiometer
channels.
