Instrument

AFSR
Actinic Flux SpectroRadiometer

The Actinic Flux SpectroRadiometer (AFSR) was an in situ spectroradiometer operated by NOAA and is now decommissioned. It made direct measurements of spectral actinic fluxes to determine photolysis rates. It operated in the 280-640 nm spectral range and had a time resolution of 1 Hz. AFSR was used for airborne and ground-based measurements.
