Spectral Radiance Experiment

Project Description
The goal of SPECTRE was to establish a reference standard
against which to compare models, and also to drastically reduce
the uncertainties in humidity, aerosol, etc., which radiation
modelers had invoked in the past to excuse disagreements with
observations. In order to avoid the high cost and sampling
problems associated with aircraft, SPECTRE was designed to be a
surface-based program.

The SPECTRE was a tightly coordinated team effort funded by two
umbrella proposals (one to DOE, one to NASA) assembled by the
authors. Highly experienced subteams carried out the three main
functions: spectrometer, remote, and in situ measurements.

Chosen spectrometers:

a large wavelength range (3-18 ?m);
high spectral resolution (1 cm-1 or better)
cryogenic cooling of the detectors; and
routine blackbody calibration in the field
