SAFARI 2000 MOPITT TROPOSPHERIC CARBON MONOXIDE, SOUTHERN AFRICA, DRY SEASON 2000

The MOPITT (Measurements Of Pollution In The Troposphere) instrument on the NASA Terra Satellite makes measurements of infrared radiation originating from the surface of the planet and isolates the energy being radiated from carbon monoxide (CO). By using appropriate data analysis techniques, concentration profiles of CO (Level-2 (L2) data) can be obtained on a global basis at a reasonably high horizontal (~22km) and vertical resolution (~3km).The MOPITT Level-3 (L3) data products provided in this data set are a subset of the daily averages from the L2 data. This subset was produced by overlaying a global 1x1-degree grid onto the L2 data, and then clipping the data to this southern Africa subset which originates at 5 degrees longitude and -35 degrees latitude and extends to 60 degrees longitude and 35 degrees latitude. Data are reported for 2 heights, 700 and 350 hPa, from daytime swaths for the period August 1-September 30, 2000, the SAFARI 2000 Dry Season Campaign.美国国家航空航天局（NASA）Terra卫星搭载的MOPITT（对流层污染测量仪，Measurements Of Pollution In The Troposphere）仪器，可探测源自地球表面的红外辐射并分离出一氧化碳（CO）的辐射能量。通过恰当的数据分析手段，能够在全球范围内获取一氧化碳浓度廓线数据（二级（Level-2, L2）数据），其水平分辨率约为22千米，垂直分辨率约为3千米，具备较高的观测精度。本数据集提供的MOPITT三级（Level-3, L3）数据产品，为二级数据日平均值的子集。该子集的生成流程为：将全球1×1度网格叠加至二级数据中，随后将数据裁剪至南部非洲子集，该子集的空间范围为经度5°至60°、纬度-35°至35°。数据集涵盖2000年8月1日至9月30日（SAFARI 2000旱季科考活动期间）日间扫描带的两个气压高度层数据，分别为700百帕与350百帕。
