The China Meteorological Administration established meteorological industry measurement standards of photosynthetic effective radiation and ultraviolet radiation in 2010. The various performance indexes of calibrators must be verified by practical tests after the standards are put to use. By testing the wavelength precision, accuracy, stray light, repeatability, stability, and the cosine response of the optical input unit in the spectroradiometer, as well as evaluating the sources of errors and the uncertainty of the whole standard, it is verified that the ultraviolet radiation measurement standard, DTMC300 Multiple Grating Double Monochromator, satisfies the related technical specifications of WMO regulations.
