Creation and evaluation of a global precipitation map using satellite data

Research grant

Project Description

Research on the distribution of global precipitation and its changes are essential for clarifying the causal relation with climate change, establishing a water circulation model, conserving water resources, maintaining an ecological environment and predicting agricultural productivity. As a result, it is important to create a global precipitation map based on reliable observations, which utilizes data from satellites. This purpose of this research is to create a global precipitation map over 3 years using a microwave radiometre equipped man-made satellite and infrared radiation data in order to evaluate this research under an international collaborative research framework. Our assessment will also include the evaluation of precipitation maps created by each country's research team participating in the IPWG/PEHRPP (an organization sponsored by the World Meteorological Organization). This research consists of cooperation between five organisations; Kyoto University, Osaka University, Tottori University of Environmental Studies, Japan Aerospace Exploration Agency(JAXA) and the National Institute of Information and Communications Technology.
