论文摘要
在8年的夏季，在爱沙尼亚东南爱沙尼亚东南部的涂片研究站附近的半北方地区，在夏季收集了下降太阳辐射的系统光谱测量。这些测量结果提供了有关波长在波长范围为300至2160 nm的光谱和总体和弥漫性辐照度变化的信息，在SWIR光谱区域的紫外线为3 nm，光谱分辨率为3 nm。已经收集了独特的数据，并提供了测量光谱变异性的定量描述。为了描述测量过程中的概要情况，而不是云覆盖，使用了320---1800 nm的光谱范围内测量的总辐照度的比率。该比率可以用作主要的气象参数，而不是难以通过工具测量的云覆盖物。
Systematic spectral measurements of downwelling solar radiation, both of global and diffuse, have been collected in summertime during 8 years in the hemi-boreal zone in south east Estonia near the SMEAR-Estonia research station. The measurements provided information about the variation of spectral and total, global and diffuse irradiance in the wavelength range from 300 to 2160 nm with spectral resolution of 3 nm in UV to 16 nm in SWIR spectral regions. Unique data have been collected and quantitative description of the variability of the measured spectra is provided. For the description of the synoptic situation during measurements, instead of cloud cover, the ratio of measured to possible total irradiance in the spectral range of 320--1800 nm is used. This ratio could be used as the primary meteorological parameter instead of cloud cover which is difficult to measure instrumentally.
