The domain of “JAXA Realtime Rainfall Watch (GSMaP_NOW)” was extended to the whole globe on 26th June 2019. Global rainfall data is now available in realtime.
JAXA Realtime Rainfall Watch provides realtime rainfall information even over the area lacking ground-observation network and/or oceans, which leads to the utilization for rainfall monitoring in Asia-Pacific regions so far. It is expected to expand the utilization for area other than Asia-Pacific regions.
As a utilization case of GSMaP_NOW, it has been used for realtime rainfall monitoring especially by users in the Pacific Islands surrounded by oceans where ground-based observation is limited. They have monitored current rainfall distributions over the area around their Islands. However, GSMaP_NOW over the Pacific regions outside of the Himawari domain was not available in realtime. We got request from users in these regions (i.e. French Polynesia) to extend the domain to the eastward from the Himawari domain. This extention of GSMaP_NOW to the whole globe can meet these needs.
How to use the website is from here.
