Abstract

Photoelectric detectors for the measurement of photolysis frequencies of different trace gases in the atmosphere are described. They exhibit uniform response characteristics over one hemisphere (2π sr) and wavelength characteristics closely matched to those of the photolysis frequencies JO1D, JNO2, and JNO3, respectively. Absolute calibration of the JO1D detector was performed by chemical actinometry with an accuracy of ±16 percent. Simultaneous measurements of JNO2 and JO1D are presented.
