摘要
极轨气象卫星大气垂直探测(TOVS)资料微机处理系统可实时接收处理TOVS/HRPT资料,生成空间分辨率约75(或50)km的大气温度和湿度廓线、位势高度、热成风、大气中水汽总含量、射出长波辐射(OLR)、臭氧总含量等大气参数以及TOVS水汽图象等产品。其中,大气温度的平均相对误差为2.5K,大气湿度的平均相对误差为25%。由于气象卫星覆盖范围广,观测频次多,因此,TOVS产品可弥补海洋、高原、沙漠等地区常规探测资料之不足。
The PC based TOVS data processing system developed by National Satellite Meteorology Center can process the atmospheric vertical sounder (TOVS) data in real time for the polar meteorological satellites and generate a variety of digital and graphical products,such as atmospheric temperature and moisture profile,geopotential height,thermal wind,total precipitable water vapor amount,outgoing longwave radiation (OLR),total ozone amount,TOVS water vapor images and so on.RMS errors is about 2 5K for atmospheric temperature profile,25% for water vapor profile.Because of the larger coverage of the meteorological satellites and the more frequency of satellite observations,TOVS products may be more useful to the regions that lack conventional data,such as the ocean,the plateau,the desert and so on.
