Introduction

This page provides information on the following in relation to calibration for JMA's geostationary satellites:

  • Instrument specifications
  • Calibration events (geometric and radiometric)
  • Data outages
  • Instrument monitoring
  • Re-calibration
  • Relevant Documents

In addition, "JMA's GSICS Calibration page" provides inter-calibration techniques and their monitoring informaion.

Please select satellite.
