Atmospheric Radiation Investigations and Measurements (ARIM)

Scientific Objectives

  • Actinic flux measurements and calculation of photolysis frequencies
  • Ozone column calculations
  • Irradiance measurements
  • Comparison of atmospheric measurements with radiative transfer models
  • Development of new techniques for atmospheric measurements
