摘要
海面上空气溶胶的产生和传输在一定程度上和风有关,研究气溶胶和风速间的关系,对增加大气模式的预测精度有重要意义.使用CALIPSO卫星CALIOP激光雷达L2(V3.01)气溶胶层与云层数据,与准同步AQUA卫星的AMSR-E海面风速数据,采用2007年和2008年1月、4月、7月、10月共8个月的观测数据,研究波长为532 nm的气溶胶光学厚度(AOD)与海面风速间的关系及其随季节、年份的变化.结果显示,无云条件下,全球海洋上空AOD与风速存在关系:当风速在0~12 m/s时,AOD随风速增大而增加,当风速在4~12 m/s时,AOD与风速近似线性关系,当风速大于14 m/s时,AOD趋于平稳.
Aerosol production and transmission over oceans are related to wind in some extent.Research on the relationship between wind speed and aerosol might increase the accuracy of forecast,which has important meaning to atmospheric model.The relationship between aerosol optical depth(AOD) and sea surface wind speed was explored using remotely sensed data from cloud-aerosol lidar with orthogonal polarization(CALIOP) on board CALIPSO satellite and collocated advanced microwave scanning radiometer(AMSRE) on board AQUA satellite.Measurements in eight months(January,April,July and October,2007 and2008) were used to study the relationship between sea surface wind speed and AOD at the wavelength of532 nm,and its changes with seasons and years.The results show that,in cloud free condition,aerosol optical depth over global ocean is related to sea surface wind speed.For wind speed less than 12 m/s,AOD increases with wind speed.For wind speed between 4 m/s and 12 m/s,AOD increases quasi-linearly with the increase in surface wind.For higher wind speed values,i.e.wind speed is more than 14 m/s,and the relationship shows a tendency toward leveling off.
