A major goal of introducing the coming WMO Integrated Global Observing System (WIGOS) is to meet user requirements via the provision of weather-related products based on the integration of quality-controlled observation data from various platforms.

In this context, the Japan Meteorological Agency (JMA) launched its Weather Analysis Map product on 15 March 2016 to provide two-dimensional information on expected weather conditions (i.e., sun, cloud, rain, rain/snow and snow) and temperatures with a 1.0-km horizontal resolution and hourly updates. The wide range of observation data used to create the product includes information from JMA automatic weather stations (AMeDAS), as many as 10,000 rain gauges managed by central and local government bodies, weather radars run by JMA and Hydrological Service, and the Himawari-8 geostationary meteorological satellite, in addition to climatological normals and numerical prediction model data.

With its nationwide coverage and consistent quality, the Weather Analysis Map product allows users to find out about current weather conditions anywhere in the country without the need to consider individual data sources of WIGOS component observations.
