1. Introduction
IDI-Japan had been operating "Global Flood Alert System (GFAS)” on the website since April 2006 and started operations of GFAS II (ver.2.0) in June 2015 which additionally utilized GSMaP_NRT*¹, the precipitation obtained by analysis of observation data from multiple
GSMaP_NRT
GFAS II   provides  precipitation  data  observed by satellites using Global Grid (with latitude and longitude of 0.1 degree width, which is approximately 11 km in equatorial regions), conducts risk assessment by occurrence probability (return period) in each grid, and updates the data hourly in the map. Japan  Aerospace  Exploration  Agency  (JAXA) started delivering GSMaP_NOW in 2015 which provides precipitation in almost real time. The new version of GFAS II (ver.2.1) utilizes the data of GSMaP_NOW and can show a global risk map of possible rain related disasters about 1 hour late. The revised GFAS II (ver.2.1) is available in the following web sites since June 2017. 2. How to use, environment Please use a personal computer (recommended browser is IE) and can be used on smartphone. The revised GFAS II (ver.2.1) is available in the following web sites since June 2017.

3. Major Improvements of GFAS II (ver.2.1)
✓Utilization of GSMaP_NOW
✓Updating probability of precipitation occurrence (probability distribution form): For the precipitation in the past, data by the latest JAXA products, RNLver6 and MVKver6 are used as well as precipitation data of the recent 2 years and data of the past 16 years. ✓Extension of movie display time ✓Burmese now available: You can choose from six languages; English, Spanish, German, Vietnamese, Burmese and Japanese. GSMaP_NRT is the near real time version which provides global precipitation data about 4 hours late with high resolution (with temporal resolution; 1.hour and special resolution; latitude and longitude grid of 0.1 degree width) GSMaP_NOW is the quasi-real time version of GSMaP_NRT which provides precipitation data within the observation range of Stationary predicting Satellite HIMAWARI by precipitation of 30 minutes later using cloud motion vector observed by HIMAWARI. NOTE: In GFAS II , GSMaP_NRT shows data about 4 hours late, and GSMaP NOW shows about 1 hour late. GSMaP_NOW is higher in immediacy than GSMaP_NRT, however, tends to be lower in qualitative accuracy.

Infrastructure Development Institute (IDI)-Japan is a general incorporated association operating under the guidance of Ministry of Land, Infrastructure, Transport and Tourism of Japanese Government. IDI provides consulting services for mobilizing International Assistance to developing countries, promoting international exchange of information and human resources, and supporting globalization of project implementation systems targeting both developed and developing countries in the field of infrastructure. IDI has been publishing the free quarterly journal "IDI Quarterly" since1996 for the purpose of introducing information relating to public works and construction technologies developed in Japan to foreign countries. We have distributed the journal to administration officials in more than 90 countries around the world by e¬ mail. It is highly appreciated if you would send us your opinions, impressions etc on the articles. We are also welcoming your specific requests on articles to pickup for the following Quarterly issues.
