The length of MWRI service aboard FY-3B exceeds the instrument's design life, some of the components could no longer work normally for measurement, therefore, NSMC made the ultimate decision that the MWRI instrument be powered off forever from September 3, 2019, relevant data and product service have also stopped. Given the supply of the extra power on FY-3B, after analyzing the status of ERM-1 instrument, NSMC also made the decision to switch on the instrument of Earth Radiation Measurment-1 and resume the relevant data service.
