DESCRIPTION:The Regional Arctic System Model (RASM) has been developed and
  used for modeling of past to present and prediction of future Arctic clim
 ate change at time scales from weeks to decades. RASM is a fully coupled l
 imited-domain ice-ocean-atmosphere-land hydrology model including the mari
 ne biogeochemistry. Its domain is pan-Arctic\, extending far into the Nort
 h Pacific (~30 degN) and the North Atlantic (~40 degN) oceans. The default
  atmosphere and land components are configured on a 50-km grid. The ocean 
 and seaice components are configured on rotated sphere meshes with the def
 ault configuration of 1/12-deg (~9.3km) in the horizontal space and with 4
 5 vertical layers. High-resolution model configurations include the atmosp
 here/land at 25-km and ice-ocean at 2.4-km grids. As a regional climate mo
 del\, RASM requires boundary conditions along its lateral boundaries and i
 n the upper atmosphere\, which are derived either from global atmospheric 
 reanalyses for simulations of the past to present or from Earth System mod
 els (ESMs) for climate projections. The hindcasts allow comparisons of RAS
 M results with observations in place and time\, which is a unique capabili
 ty not available in global ESMs.
