将简化紫外辐射传输模型应用于OMI卫星传感器数据,研究西太平洋地区B波段(UVB)的紫外辐射,其中卫星数据取自OMI传感器中L2级数据,地面实测数据取自加拿大全球紫外辐射中心(WOUDC)。将模型反演的UVB辐射数据与位于西北太平洋的两个典型站位实测数据进行了比较,结果显示卫星反演的UVB数据与地面实测数据具有很好的一致性,表明该简化的紫外辐射传输模型在基于OMI卫星传感器数据反演西太平洋地区的UVB辐射时具有良好的适用性。利用卫星反演的UVB数据,研究了西太平洋地区UVB辐射的时间及空间变化规律,这些变化规律与已有的观测结果一致。
The simplified UV radiation transmission model was applied to OMI satellite sensor data to study ultraviolet B radiation in the western Pacific. The satellite data were taken from L2 data of OMI sensor. The measured data were taken from the Global UV Radiation Center of Canada (WOUDC ). Comparison between the UVB data retrieved from the model and the measured data from two typical stations located in the northwestern Pacific shows that the UVB data retrieved by the satellite are in good agreement with the measured data from the ground, indicating that the simplified UV radiation transmission The model has good applicability in the inversion of UVB radiation in the western Pacific based on OMI satellite sensor data. Using the UVB data retrieved from satellite data, the temporal and spatial variations of UVB radiation in the western Pacific are studied. These changes are consistent with the observed results.
