Abstract:
A high resolution (daily, 250m) land ice and tundra meltwater discharge dataset for the period 1950-2021 in an easily accessible and storage efficient database covering most of the Arctic and sub-Arctic North Atlantic (SNA) ocean region, i.e. Canadian Arctic Archipelago, Greenland, Iceland, Svalbard, Russian Arctic Islands. We distribute 3 files for each Randolph Glacier Inventory v.6.0 first order region studied. These regions are RGI-03 Arctic Canada North (CanadaN), RGI-04 Arctic Canada South (CanadaS), RGI-05 Greenland (Greenland), RGI-06 Iceland (Iceland), RGI-07 Svalbard and Jan Mayen (Svalbard), RGI-09 Russian Arctic (RussiaN). In addition, we distribute a single pan-Arctic file (panArctic_MonthlyBasinRunoff.nc). Meltwater discharge is derived from daily ~6 km regional climate model, Modéle Atmosphérique Régional (MAR), runoff simulations that are statistically downscaled and routed to the coastlines. The statistical downscaling algorithm uses native vertical gradients of the MAR data and high resolution (250 m) DEM, land mask (Copernicus GLO-90) and ice mask (GIMP, RGI) datasets. Routing to coastal outflow points is performed by a hydrological routing scheme applied to the high-resolution DEM and the downscaled runoff. Meltwater components from non-glaciated land, bare glacier ice and glaciated area above the snowline are separated to facilitate further analysis.
