光合有效辐射和紫外辐射测量标准的性能验证

2010年中国气象局建立了气象行业光合有效辐射和紫外辐射测量标准.标准建成后,标准器的各项技术性能指标必须经过实际测试来验证.通过对光谱辐射计的波长精密度、准确度、杂散光、重复性、稳定性、探头余弦响应等参数的测试验证,以及对整个标准的测量误差来源及不确定度的分析和评定,得以验证紫外辐射测量标准DTMc300双单色仪光谱辐射计满足世界气象组织(WMO)相关规定的技术指标要求.

Performance Verification of Photosynthetic Effective Radiation and Ultraviolet Radiation Measurement Standards

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 he 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.
