Our data comes from The European Centre for Medium-Range Weather Forecasts (ECMWF), an independent intergovernmental organization. We build daily and monthly graphs for visualization using Python and R graphs that can be found here.
The geographic resolution of ECMWF's data is unfortunately only 0.1 degrees, about 12 km * 12 km. In the future we wish to use data from the Himawari satellite that has higher resolution.
