A CCD Spectroradiometer for Ultraviolet Actinic Radiation Measurements
|
ABSTRACT
A new spectroradiometer for spectral measurements of ultraviolet (UV) atmospheric radiation (290-400 nm) using a charge coupled device (CCD) as a detector is introduced. The instrument development is motivated by the need for measurements with (a) high accuracy in the UV-B spectral range (290-315 nm) for photochemistry applications and (b) high temporal resolution in quickly changing atmospheric conditions such as partial cloud cover. The new CCD instrument is mainly intended for airborne use. It allows fast data collection (<300 ms time resolution for each spectrum) with improved ...
