HDF5 format data obtained from G-Portal using a graphical user interface can be converted into GeoTIFF files through map projection. |
JASMES (Click to go to the TOP page of JASMES Portal) |
Datasets for global environmental change research are available in netCDF, GeoTIFF and other formats. You can download GeoTIFF data with "FAI monitor" and "Ibay Monitor". You can download map-projected netCDF data around Japan with "SGLI Near-realtime Monitor" and around Japan and the globe with "SGLI Standard Data." User registration is required to download the data, but no registration is required to view it. |
G-Portal Processing Request (Click to go to G-Portal TOP page) |
A G-Portal feature allows you to produce GeoTIFF files from the "Processing" button in the search results. User registration is required to download the data and make processing requests. |
JASMES sites using SHIKISAI data are summarized in "Data Acquisition" in the menu above.
This site explains how to use the "SGLI Map projection & GeoTIFF Conversion Tool" for map projected GeoTIFF conversion of Level-1B, Level-2, and Level-2 statistic products obtained from G-Portal, and how to use "gdal(QGIS)" for GeoTIFF conversion of Level-3 products.
