Description
The Solar Spectral Flux Radiometer (SSFR) is used to measure
solar spectral irradiance at moderate resolution to determine
the radiative effect of clouds, aerosols, and gases on climate,
and also to infer the physical properties of aerosols and
clouds. The newest version of the SSFR was designed primarily
for airborne platforms and thus it has no moving parts. Two
instruments were built and successfully deployed in three field
missions: 1) the Department of Energy Atmospheric Radiation
Measurement (ARM) Enhanced Shortwave Experiment (ARESE) II in
February/March, 2000; 2) the Puerto Rico Dust Experiment (PRIDE)
in July, 2000; and 3) the South African Regional Science
Initiative (SAFARI) in August/September, 2000. Additionally, the
SSFR was used to acquire water vapor spectra using the Ames
25-meter base-path multiple-reflection absorption cell in a
laboratory experiment.
