Abstract

The data from the Earth observation satellites "ADEOS-II (Midori 2)", "ADEOS (Midori)", "JERS-1 (Fuyo 1)", "MOS-1 (Momo 1)", and "MOS-1b (Momo 1b)", which ceased orbital operations by the Japanese fiscal year 2023, are archived at JSS.

These historical satellite data are crucial for research that promotes the understanding of long-term Earth environmental changes. They are extremely important and must not be lost.

Reasons and benefits of using JAXA Supercomputer System

Earth Observation data Although these data are also provided via the Earth Observation Satellite Data Distribution System (G-Portal), in case of a major disruption of G-Portal, data can be recovered from JSS.
