Instrumentation and Measurement of Atmospheric Radiation

Instrumentation and Measurement of Atmospheric Radiation
This lesson outlines the importance of measurements of atmospheric radiation and describes the main types of instrumentation used in obtaining these measurements. Solar radiation instrumentation described includes 1) thermal detectors (pyranometers and pyroelectric radiometers), 2) spectral instruments, and 3) instruments for direct and diffuse components of the radiation. Terrestrial radiation measurements include both broadband and spectrally resolved measurements. Actinic flux density measurements and measurements from special platforms, including airborne observations, are also described. The lesson is part of the "Instrumentation and Measurement of Atmospheric Parameters" course and is intended primarily for undergraduate and graduate students with some previous knowledge of atmospheric science and mathematics.
