The region averaged measured surface temperature are 18.0℃, 30.4℃ and 19.5℃ with the maximum regional changes of 6.3℃, 8.3℃ and 7.6℃. Surface temperature obtained after making correction for the air transmissivity and the emissivity of the surface covering substances underlying the flying aircraft is found to be 3 to 4 degree higher.\nA case study of 1997 water balance in the same setup region demonstrated that the averaged annual rainfall and evapotranspiration amounts are 2220 and 1070 mm, respectively, resulting in the discharge of water being about 50% of the rainfall amount., 紀要論文}, pages = {49--62}, title = {沖縄本島北部の地表面温度観測と水収支の予備解析}, year = {2000} }
