Abstract

In situ meteorological forcing and evaluation data, and bias-corrected reanalysis forcing data for cold regions modelling at ten sites: one maritime (Sapporo, Japan), one arctic (Sodankylä, Finland), three boreal (Old Aspen, Old Jack Pine and Old Black Spruce, Saskatchewan, Canada) and five mid-latitude alpine (Col de Porte, France; Reynolds Mountain East, Idaho, USA, Senator Beck and Swamp Angel, Colorado, USA; Weissfluhjoch, Switzerland).

The long-term datasets are the reference sites chosen for evaluating models participating in the Earth System Model-Snow Model Intercomparison Project (ESM-SnowMIP). Periods covered by the in situ data span from 1994 to 2016 with the period of available data varying by location from between 7 and 20 years of hourly meteorological data, with evaluation data (snow depth, snow water equivalent, albedo, soil temperature and surface temperature) available at varying temporal intervals.

30-year (1980-2010) time-series have been extracted from a global gridded surface meteorology dataset (Global Soil Wetness Project Phase 3) for the grid cells containing the reference sites, interpolated to one-hour timesteps and bias corrected.

Title Bias corrected time-series data extracted from the global gridded surface meteorology dataset Global Soil Wetness Project Phase 3) for grid cells containing the ESM-SnowMIP reference sites
Abstract 30-year (1980-2010) time-series have been extracted from a global gridded surface meteorology dataset (Global Soil Wetness Project Phase 3) for the grid cells containing the Earth System Model - Snow Model Intercomparison Project (ESM-SnowMIP) reference sites, interpolated to one-hour timesteps and bias corrected. Although applied to all sites. The bias corrections are particularly important for mountain sites that are hundreds of meters higher than the grid elevations; as a result, uncorrected air temperatures are too high and snowfall amounts are too low in comparison with in situ measurements. The ten in situ sites are characterised as maritime (Sapporo, Japan), arctic (Sodankylä, Finland), boreal (Old Aspen, Old Jack Pine and Old Black Spruce, Saskatchewan, Canada) and mid-latitude alpine (Col de Porte, France; Reynolds Mountain East, Idaho, USA, Senator Beck and Swamp Angel, Colorado, USA; Weissfluhjoch, Switzerland). The locations of the in situ measurement sites are listed as follows: CDP (Col de Porte), Latitude: 45.29, Longitude: 5.77, Elevation: 1325.0 m, Location: France; OAS (Old Aspen), Latitude: 54.05, Longitude: -106.33, Location: Canada; OBS (Old Black Spruce), Latitude: 54.65, Longitude: -105.20, Location: Canada; OJP (Old Jack Pine), Latitude: 54.53, Longitude: -105.00, Location: Canada; RME (Reynolds Mountain East), Latitude: 43.19, Longitude: -116.78, Location: United States; SAP (Sapporo), Latitude: 43.06, Longitude: 141.33, Elevation: 17.0 m, Location: Japan; SNB (Senator Beck Basin Study Area (SBBSA)), Latitude: 37.91, Longitude: -107.73, Location: United States; SOD (Sodankyla), Latitude: 67.42, Longitude: 26.59, Location: Finland; SWA (Swamp Angel Study Plot (SASP)), Latitude: 37.91, Longitude: -107.71, Elevation: 3371.0 m, Location: United States; WFJ (Weissfluhjoch), Latitude: 46.83, Longitude: 9.81, Location: Switzerland.
