Mean Sea Level to OD Malin (OSGM15) Corrective Surface (ICWWS 2018 - Phase 4)

Abstract: This dataset provides an estimate of the relationship between Mean Sea Level (MSL) and OD Malin (OSGM15) around the coast of Ireland. The sign convention indicates OD Malin (OSGM15) relative to MSL, i.e. at a location where the OD Malin (OSGM15) surface lies above MSL a positive value appears and at a location where the OD Malin (OSGM15) surface lies below MSL a negative value appears. If a water level is derived to MSL, the correction value is subtracted to convert this value to OD Malin (OSGM15). Users of this data should refer to the Irish Coastal Wave and Water Level Modelling Study 2018 Phase 4 Technical Report that can be found on https://www.floodinfo.ie/publications/.

Purpose: Phase 4 of the Irish Coastal Wave and Water Level Modelling Study (ICWWS) 2018, provides an estimate of the relationship between Mean Sea Level (MSL) and OD Malin (OSGM15) around the coast of Ireland.
