OUTLINE

Objectives of this symposium are to wrap up the workshops held three times during the CREST research period and to publicize research results of GSMaP research team internationally. Moreover, we aim to continue refinement of the research results, not to hoard them, in order to contribute to future precipitation observations by satellites such as GPM. To this end, algorithm developers, creators of precipitation maps, and users of precipitation maps from the world will gather to discuss intensively further development of high-accuracy, high-resolution global precipitation map. Thus, we can expect that, as a consequence of information exchanges and discussions by researchers from various fields, excellent algorithm and maps will be developed.

Specifically, GSMaP research team will present: (1) development of the algorithm to calculate precipitation intensity using precipitation observation data obtained from satellite onboard equipment such as microwave radiometer, precipitation radar, and infrared radiometer; (2) research on creation of high-temporal, high-resolution global precipitation map which is made by analyzing data from microwave radiometers and infrared radiometers by using the above algorithm; and (3) research results in and after CREST on evaluation and practical application of the precipitation maps produced. Further, after reporting by invited foreign researchers on the latest research results achieved by investigators in this field across the world, we will have questions and answers on the reports. Through these sessions, we would recognize the current research status in the world, obtain information for further improvement of algorithm/map generation and map application, and eventually contribute to the advancement of the research while transmitting the outcomes of GSMaP research team world-widely.
