沙尘暴过程地面测量与卫星同步观测实验及数据分析——以2002年沙尘暴事件为例

In Situ Measurement and Satellite Observation Experiment and Data Analysis in the Course of Dust Storm

2001年中日亚洲沙尘暴项目ADEC在中国的新疆、甘肃、陕西、内蒙、北京、青岛以及韩国和日本布设了雷达气溶胶探测仪、沙尘颗粒收集仪、风速测量仪,结合利用卫星技术,于2002年4～5月对起沙、输送和沉降开展了实时监测和测量,获得地面风速、TSP、PM及地表温度等实测数据。以2002年3(4月沙尘天气为例,空中观测与地面监测密切结合,综合分析卫星遥感数据和地面实测数据,为沙尘暴综合分析与预测提供了基础数据。

In 2001, some in situ measurement stations were setup by Asia Dust Storm Project, ADEC, in Korea, Japan and Xinjiang, Gansu, Shaanxi, Nei Mongol, Beijing, Qingdao of China. Many instruments were fixed in those places, for example aerosol detector, dust particle gatherer, wind speed measuring apparatus and so on. Combined with remote sensing technology, they were used to measure the emission, transport and deposition of dust storm. In April and May, 2002, through these instruments, the wind speed, TSP, PM and LST(land cover temperature) data were obtained. In this article, taking example for the dust storm in March and April, 2002, combining satellite data with in situ measurement data, some basic data may be provided to general analysis and forecast of dust storm.
