Upstream

[For each upstream mask product you used, copy and repeat this section. Or remove if no upstream mask]

• What upstream mask product did you use?
  HIRHAM5 has two resolutions of 0.11degree and 0.44 degree , with an ice mask derived from data created by the United States Geological Survey (USGS) Earth Resources Obser- vation and Science (EROS) Center and consisting of Ad- vanced Very High Resolution Radiometer (AVHRR) data at a 1 km resolution collected from 1992 to 1993 (Eidenshink and Faudeen, 1994)

Other notes

The HIRHAM5 ice mask includes ice shelves. All kind of processing on grounded ice or basins are done after the model has been run.
