THE PERFORMANCE MEASUREMENT OF CHINA-MADE SILICON DOMES OF PYRGEOMETER

The dome is a key component of pyrgeometer, the performance of which would influence the quality of pyrgeometer. By using the data Lowtran 7 and the data of transmittance for some kinds of China-made domes, the performance indexes of effective transmittance for some kinds of domes are calculated in different model atmospheres. The results show that the performance indexes of China-made dome are not lower than those of Eppley.
