Fierce cyclone SIDR directly hit the coastal area of southern Bangladesh on November15, 2007. Officials in Bangladesh said over 2,000 people were killed on November 18, and some newspaper predicted the death toll would rise.
Figure 1 depicts the Global Rainfall Map*2 as observed at 0600 UTC, November 14, 2007, and the cyclone SIDR approaching Bangladesh in near-real time. The movie depicts SIDR traveling north in the Bay of Bengal.

Figure 2 depicts the accumulated rainfall based on near-real-time hourly data from 10 to 16 November 2007. The accumulated rainfall intensity (yellow to red area) fit SIDR's path. In this figure, you can see SIDR passing east-northeast after landing in the coastal area of Bangladesh from the Bay of Bengal. The quantitative rainfall amount produced by the cyclone is also presented.

*2 JAXA EORC have provided hourly high-resolution Global Rainfall Map in Near-Real Time (about four hours after observation) using data observed by TRMM and other satellites since this November.
The rainfall amount from the "Global Rainfall Map in Near-Real Time by JAXA EORC" is calculated by an algorithm developed by the Global Satellite Mapping of Precipitation (GSMaP) project sponsored by the Japan Science and Technology Agency (JST). The main feature of the GSMaP algorithm is utilization of various attributes derived from TRMM PR, the first spaceborne precipitation radar. Our cost for providing the rainfall data (four hours after the observation) is competitive for a global rainfall product using microwave radiometers.
Frequent rainfall data and information for Asia, where cyclones and weather disasters occur frequently, is now available from several satellite systems.
