HARP-Actinic Flux

The HIAPER Airborne Radiation Package (HARP) instrumentation is a comprehensive atmospheric radiation suite to measure spectrally resolved actinic flux and irradiance. HARP was developed in a collaborative effort between NCAR, the University of Colorado, the Leibniz-Institute for Tropospheric Research, Metcon, Inc and Enviscope GmbH. The package is part of the HIAPER Aircraft Instrumentation Solicitation (HAIS), funded by NSF. Aircraft deployments include the NSF/NCAR GV and C-130 aircraft.

HARP-Actinic Flux

The actinic flux instruments were recently upgraded to allow for faster time response, noise reduction, improved reliability and long-term stability. The upgrades included improved spectrometers, modern electronics, temperature control, a compact NUC computer, and updated data acquisition and control software.
