  • Processing Version: v0.2.0

  • Processing Datasource*: arcticgateway

  • Product Version: v0

  • Variable Mapping*: {‘time’: ‘TIME’, ‘depth’: ‘DEPTH’, ‘lon’: ‘LONGITUDE’, ‘lat’: ‘LATITUDE’, ‘v’: ‘VCUR’}

  • Original Variable Metadata*: [Complex metadata structure - 7 items]

  • Applied Variable Mapping: {‘time’: ‘TIME’, ‘depth’: ‘DEPTH’, ‘lon’: ‘LONGITUDE’, ‘lat’: ‘LATITUDE’, ‘v’: ‘VCUR’, ‘TIME’: ‘TIME’, ‘DEPTH’: ‘DEPTH’}

  • Gateway: FramStrait

  • Adjustments: v is adjusted by a constant monthly value obtained from the inverse model, for all grid cells in a segment

  • Depth Limit: None

  • Segments Format: Python dictionary converted to a string. The slices can be applied in xarray coordinate selection

  • Segments: {‘EGS’: {‘long_name’: ‘East Greenland Shelf’, ‘lon_slice’: slice(None, -10.6, None)}, ‘EGC’: {‘long_name’: ‘East Greenland Current’, ‘lon_slice’: slice(-10.6, -0.6, None)}, ‘CFS’: {‘long_name’: ‘Central Fram Strait’, ‘lon_slice’: slice(-0.6, 5.1, None)}, ‘WSC’: {‘long_name’: ‘West Spitsbergen Current’, ‘lon_slice’: slice(5.1, 8.805, None)}, ‘WSS’: {‘long_name’: ‘West Spitsbergen Shelf’, ‘lon_slice’: slice(8.805, None, None)}}
