STUDYING THERMAL ANOMALY BEFORE EARTHQUAKE WITH NCEP DATA
Thermal Anomaly Earthquake NCEP
2015/12/28
Thermal anomaly before earthquake was widely studied with satellite data such as NOAA/AVHRR and MODIS. A big disadvantage is that satellite thermal sensor can not penetrate thick clouds to retrieve su...
Evaluation of operational INSAT-3D UTH product, using Radiosonde, Meteosat-7 and NCEP Analysis
Water Vapor Upper Tropospheric Humidity INSAT-3D Radiosonde Meteosat-7
2014/12/15
Recently available satellite observations from the water vapor channel (6.5–7.1 μm) of the Imager on-board India's geostationary satellite, INSAT-3D have been used to estimate Upper Tropospheric Humid...
对流层延迟是卫星导航定位的主要误差源,气象观测的数值预报资料可用来计算对流层延迟改正量.本文通过分布于亚洲地区的49个GPS台站一年的实测ZTD资料,对利用欧洲中尺度天气预报中心(ECMWF)分析资料、美国国家环境预报中心(NCEP)再分析资料和NCEP预报资料,计算对流层天顶延迟(ZTD)改正的有效性和可能达到的精度进行了评估,分析了ECMWF和NCEP在亚洲地区的适用程度和其分辨率对计算ZTD...
