Analyses using satellite data
For the purpose of understanding and predicting the climate-system, it is necessary to know the present condition.
Therefore, it is indispensable to obtain the global data reguraly. However it is difficult to obtain whole global data
merely by ground observations. In this context, observations using satellite data have begun to attract attention. In
order to increase the efficiency of using satellite data, validation with ground observation data and with GCM(General
Circulation Model) have been performed.
