HARP  

Definition

  • More information: https://www.eol.ucar.edu/instruments/hiaper-airborne-radiation-package The instrument consists of two components: actinic flux: 280-680 nm, spectrally resolved, up and down This system consists of two hemispheric light collectors, each connected by fiber optics to a monolithic solid state spectrograph with a CCD detector. The spectral resolution is about 1.8 nm, and the field of view is the full sky up and down. The measurements then characterize the radiation environment responsible for photochemistry. The upward-viewing light collector is mounted on the top of the tail to avoid shielding by the tail. spectral irradiance: 260-2217 nm, spectrally resolved, on stabilized platforms up and down This system consists of spectrometers viewing up and down. A light collector with response proportional to the cosine of the incident radiation delivers the radiation to the spectrometers. To extend the range of wavelengths, two spectrometers are used in each direction; one is used to extend the wavelength coverage into the near IR. (en)
