land: Polygon of land

In IceCast: Apply Statistical Post-Processing to Improve Sea Ice Predictions

Description

Land mask as a single SpatialPolygons object. The land mask was obtained from the CM2.5 Forecast-oriented Low-Ocean Resolution (FLOR) model produced by the National Oceanic and Atmospheric Administration’s Geophysical Fluid Dynamics Laboratory converted to a Polar Stereographic grid. (Vecchi et al. 2014; Msadek et al. 2014). Weights for converting to a polar stereograhic grid were obtained from the spherical coordinate remapping and interpolation package (SCRIP) (Jones 1997).
