  9. Summary ● Overall MHS calibration is good with most of the quality control flags being properly set ● On-orbit MHS NET at each channel meets specification ● Missing data: whole orbit ● Sudden Jump/Drop in Calibration Counts: Problematic ● Recommend: Implement the Sudden Jump Correction Algorithm in the Operational Software - High Priority Metop-A MHS Cal/Val
