Development of a SWIR solar spectral radiometer for the ARM program. Final report
The goal of this grant was to develop an absolutely calibrated spectral radiometer covering the 1 to 5 {micro}m spectral region of the DOE ARM (Atmospheric Radiation Measurements) program. This instrument is called the Absolute Solar Transmittance Interferometer (ASTI). This effort was based on earlier results from grant DE-FG02-92ER61360. The instrument is based on a small, commercially available interferometer, built by Bomem, Inc., of Quebec, Canada. For the earlier grant, the authors constructed a breadboard version of ASTI, which was used to study the linearity, zero offset, gain stability, etc. These all indicated that an instrument of this type could achieve precision of 1% or better, with accuracy limited by the calibration standards (nominally 3%). For this grant they constructed a prototype instrument for possible use at the ARM sites.
