2. About Data
2-1. Area and resolution
The target areas are Global and Japan.
The default web view is global, and when zoomed in near the Japan area, data for the Japan area is mapped. The resolution varies depending on the sensor.

4-2. Convert to GeoTiFF
This is tutorial for converting GCOM-C/SGLI data in netCDF format to GeoTiFF.
Please refer to the following depending on the data used (SGLI、MODIS).
The script in the tutorial will use Python3(netCDF4, NumPy, GDAL library).
In addition, software (SeaDAS、ncdump, etc.) to check the contents of netCDF is required.
