Instrument

SAFS
Scanning Actinic Flux Spectroradiometer

The Scanning Actinic Flux Spectroradiometer (SAFS) is an in situ airborne spectroradiometer developed by NCAR. It measures wavelength-dependent actinic flux from 280 to 420 nm. These measurements are used to calculate the photolysis frequencies for multiple species, including ozone, nitrogen dioxide, formaldehyde, nitric acid, and peroxyacetyl nitrate. SAFS has a measurement sampling rate of 0.1 Hz.
