JAXA Earth Observation Research Center (EORC) conducts calibration & validation of satellite data, and the Earth science research and application research using those data.

EORC researches in the field of earth science such as global climate change, water cycle, atmospheric environment and crustal movements, using satellite data while developing calibration & validation and analysis methods to improve data accuracy of sensors onboard earth observation satellites.



We introduce our activities on the following web sites.

The GSMaP provides large amounts of data on hourly rainfall distribution around the world over the past 20 years. You can also see the latest status from the map below.

These studies are carried out in each research project that specializes in each satellite and sensor as well as in cooperation with the combined use of satellite data and models. The results are reflected in future development of satellites.

ALOS Research and Application Project conducts the Earth science / application researches using Synthetic Aperture Radar (SAR) and high-resolution optical sensors onboard the "DAICHI" (ALOS) series satellites. ALOS Research and Application Project

GPM project conducts the Earth science / application researches and calibration & validation in the field of precipitation and water cycle using the precipitation radar onboard earth observation satellites. The precipitation radar enables observation of three-dimensional structure of rain and snow. GPM Project

GCOM-W project is conducting the Earth science / application researches and calibration & validation activities related to climate and water cycle variations using the Advanced Microwave Scanning Radiometer (AMSR) series. GCOM-W Project AMSR Series

GCOM-C project is conducting the Earth science / application researches and calibration & validation related to climate change using the Second generation GLobal Imager (SGLI) onboard earth observation satellite "SHIKISAI" (GCOM-C). GCOM-C Project

GOSAT project is conducting research and development and data calibration & validation by using sensors onboard the "IBUKI" (GOSAT) series satellites for observing greenhouse gases (carbon dioxide, methane) which are the causes of global warming. GOSAT Project

EarthCARE is an earth observation satellite mission that Japan and Europe are collaborating for development. It is expected that the mission will improve the numerical climate model and contribute to improving the accuracy of climate change prediction. EarthCARE Project

Currently, EORC is recruiting invited personnel (fixed-term staff) in each research field of GCOM-C, ALOS-2 and GOSAT. Invited Personnel Recruitment (Japanese site only) JAXA Employment Opportunities (English site)
