Instrument

DIAS
Direct beam Irradiance Airborne Spectrometer

The Direct beam Irradiance Airborne Spectrometer (DIAS) was a passive airborne spectrometer operated by NCAR. It measured direct beam solar irradiance from 280 to 650 nm. These measurements were used to calculate the line-of-sight ozone and wavelength-dependent aerosol optical depths (AOD). DIAS had a spectral resolution of approximately 1 nm.
