利用我国第二代极轨气象卫星“风云三号”搭载的紫外臭氧总量探测仪(TOU)发射后一年内获取的观测数据以及地基臭氧观测数据,对全球特别是受到广泛关注的南极地区和青藏高原地区进行了臭氧总量反演试验,反演结果与国外同类产品及地面观测结果进行了对比分析.定性的分析结果表明,“风云三号”紫外臭氧探测仪反演的全球臭氧总量分布与国际上发布的同类产品相比,真实地反映了臭氧随时间与空间的分布特征.在全球部分地基观测站所处的位置上对臭氧总量探测仪与OMI产品和地基观测数据进行了比较,结果表明,“风云三号”紫外臭氧探测仪臭氧总量反演结果和国外同类卫星产品相对均方根偏差约为3%,与地基观测结果相比相对均方根偏差约为4.2%,中低纬度地区均方根偏差小于高纬度地区,最大均方根偏差出现在南极臭氧洞之内,大多数情况小于5%,个别站点上超过5%但低于10%,均优于10%的产品设计指标.目前TOU已经完成了在轨测试和试运行进入业务运行阶段,向国内外用户提供实时臭氧总量产品.
Based on the observation data obtained within one year after launch of the TOU satellite equipped with the second generation polar orbit meteorological satellite “Fengyun III” and the ground-based ozone observation data, the global special attention has been paid to the Antarctic Area and the Qinghai-Tibet Plateau, the inversion results of the total ozone were compared with similar products from abroad and the ground observation results.The qualitative analysis results showed that the inversion of the “Fengyun III” ultraviolet ozone detector The distribution of ozone in the world reflects the distribution of ozone in time and space as compared with that of other similar products released in the world.Using the Ozone Total Detector and OMI products and foundations The results show that the relative root mean square deviation of the “Fengyun III” UV ozone detector's ozone total inversion is about 3% compared with that of foreign similar satellite products. Compared with the ground-based observation results, the relative mean square The root deviation is about 4.2%, the root mean square deviation at middle and low latitudes is smaller than that at higher latitudes, and the maximum root mean square deviation appears within the Antarctic ozone hole, which is less than 5% in most cases. More than 5% but less than 10%, are better than 10% of the product design specifications. Currently TOU has completed in-orbit testing and commissioning phase of operational use, providing real-time total ozone products to domestic and foreign users.
