GOME-2 Absorbing Aerosol Height - Metop

The Absorbing Aerosol Height (AAH) product retrieved from the GOME-2 instruments provides absorbing aerosol layer height information. For extreme aerosol events, such as the injection of volcanic ash into the atmosphere by a volcanic eruption, the height of the aerosol layer is an important input parameter for decision making in aviation safety. Other applications are climate research and air quality. Note on GOME-2A pixel sizes: On 2013-07-15, the swath width of the instrument was reduced from 1920 km to 960 km. This means that the nominal ground pixel size changed from 80 x 40 km^2 to 40 x 40 km^2.从GOME-2仪器反演得到的吸收性气溶胶高度（Absorbing Aerosol Height，AAH）产品，可提供吸收性气溶胶层的高度信息。针对火山喷发将火山灰注入大气等极端气溶胶事件，气溶胶层高度是航空安全决策的关键输入参数。该产品的其他应用场景包括气候研究与空气质量分析。 关于GOME-2A像元尺寸的说明： 2013年7月15日，该仪器的扫描幅宽由1920千米缩减至960千米。这使得仪器的标称地面像元尺寸从80×40平方千米变更为40×40平方千米。
