Abstract
To improve an accuracy of satellite cloud height measurements, a stereoscopic technique has been studied. For stereoscopic measurements by using geosynchronous meteorological satellite, a precise image navigation technique and data handling time are strictly required, that have not yet been made in the current operational service, whereas the vidicon camera image data by the ETS-III orbital satellite (Engineering Test Satellite), which has a spacial resolution of about 0.4km, is suitable for stereoscopic measurement of cloud height, because of its higher resolution and lower image distortion than can be expected in geostational meteorological satellites. The results of stereoscopic analysis of the ETS-III vidicon camera data show that the data has a capability of determining the cloud height with the accuracy of about 2.6km by preliminary data process. Therefore the ETS-III vidicon camera has an ability of offering us an useful data for cloud height determination as an operational meteorological satellite service.
