Notes RE Availability and Quality of TIROS SEMS Data



14 April 2008 MetOp SEMS Data : Data from the MetOp SEMS are occasionally bad due to spacecraft orbit manuvers. These show up as values along the HPI=0 boundary line on the boundary plots and near a value of -1 on the boundary index plot. This is a known issue at SWPC and they are working to correct the problem.
