Satellite-based rainfall data such as GSMaP are expected to be adapted to flood forecasting in ungauged basins since they can be obtained worldwide in near real-time for free. However, GSMaP is often underestimated comparing with ground gauged precipitation, which poses a problem in applying the product to flood management. To solve this problem, Shiraishi et al. developed GSMaP correction method based on its movement of rainfall area and successfully reduced the error rate in a Japanese river basin. In this study, the GSMaP correction method was applied to typhoon Morakot in Kaoping River Basin and the entire Taiwan. The results showed that the correction formula for the Yoshinogawa River Basin can be applied to the Kaoping River Basin because of the similar basin scale and rainfall type and it cannot be applied to the entire Taiwan because of the much larger basin scale. What is more, the influence of the frequency of microwave radiometer observations on the accuracy of corrected GSMaP was validated and the outcome implied the importance of the elapsed time of microwave radiometer observation as a reliability indicator for corrected GSMaP_NRT used in flood forecasting systems.

Building Research Capacity on Assessing Community Livelihood Vulnerability to Climate Change Impacts in Central Viet Nam and the Mekong River Delta CIA2009-06-Duc: Capacity Development for Adaptation to Climate Change in the Rural Coastal Zone of Viet Nam CIA2009-07-Lotia: Capacity Development of the Scientific Community for Assessing the Health Impacts of Climate Changen the past decade, APN has published yearly project reports containing abstracts of APNfunded activities that have been useful for the APN members and other interested parties. However, with the implementation of the APN third strategic phase (2010)(2011)(2012)(2013)(2014)(2015) and the need to ensure that the work of the APN reaches all stakeholders, including science, policy and civil-society communities, the APN has launched a new publication series: APN Science Bulletin.The APN Science Bulletin is an annual publication that highlights all of the projects funded and completed by the APN in the year of publication (the present year running from April 2010 -March 2011). The Science Bulletin has four main sections: 1) Featured Articles; 2) Regional Research Projects funded under the Annual Regional Call for Research Proposals (ARCP) Programme; 3) Scientific Capacity Development Projects funded under the CAPaBLE Programme; and 4) Projects funded under the APN's Focussed Activities Programme.In this first issue of the APN Science Bulletin, March 2011; all activities that were funded and undertaken since April 2010 have been included. Under featured articles, full scientific research papers have been written and cover a number of major themes in the APN's science agenda from looking at high-resolution regional climate models for food security in Southeast Asia to developing scientific capacity for Coral Reef Management in the South Pacific. Sections 2 and 3 look at the work conducted under the APN's two main pillars of activities -the ARCP and CAPaBLE programmes, respectively. Section 4 highlights projects funded through a special focussed activity undertaken from 2009-2010 on Climate Impact and Vulnerability Assessments.On behalf of the Scientific Planning Group (SPG), who advises the scientific programme of the APN to the APN's governing body, the Inter-Governmental Meeting, we, as the SPG Co-Chairs are delighted to present the first issue of the APN Science Bulletin to you and hope that you find the contents both interesting and useful for your activities in global environmental change.
