HARP
HIAPER Airborne Radiation Package

The HIAPER Airborne Radiation Package (HARP) is an in situ airborne radiometer developed by NCAR, the University of Colorado, the Leibniz-Institute for Tropospheric Research, Metcon, Inc., and enviscope GmbH. The instrument measures actinic flux and spectral irradiance. HARP operates from 280 to 680 nm for actinic flux and from 260 to 2400 nm for irradiance. It typically samples at 1 Hz.
