卫星遥感海南岛气候特征的研究

A STUDY ON CLIMATIC CHARACTERISTICS OF HAINAN ISLAND BY USING METEOROLOGICAL SATELLITE DATA

利用ＮＯＡＡ极轨气象卫星的ＡＶＨＲＲ资料，研究了海南岛干、湿两季在无云情况下的下垫面短波反射率、植被指数、下垫面温度和射出长波辐射的分布及变化特征．结果表明利用气象卫星资料可以较详细地了解气候形成的主要因素之一──下垫面状况．

Using NOAA polar-orbiting meteorological satellite data,the distribution and thechanges of the underlying surface reflectance, vegetation index,underlying surfacetemperature and outgoing longwave radiation (OLR ) are studied under the condition ofcloudfree in both dry and wet seasons in Hainan Island.It is proved that the applicationof satellite data is highly effective to the study of underlying surface regime,which isone of the important factors for the local climate.
