Abstract

An automated multichannel solar radiometer has been designed and fabricated by the Atmospheric Remote Sensing Laboratory at The University of Arizona. The automated radiometer has 10 separate silicon-photodiode-based channels that allow near-simultaneous solar spectral measurements through narrow bandpass filters (approximately 10 nm) from the visible to near-IR regions. The photodiode detectors are temperature stabilized using a heating temperature controller circuit. The instrument is pointed toward the sun via an autotracking system that actively tracks the sun with a ±0.05° tracking accuracy. The instrument can continuously collect data for about 22 h at once per minute sample rate. This paper presents instrument design features as well as some performance and experimental results for the automated solar radiometer.
