Data Sources for Greenland
|Field Description:||Reference:||Notes:||CF Name:||Units:|
|Precipitation|| van der Veen, Bromwich, Csatho and Kim (2001)
|| This data is in meters/year (water equivalent).
The grid was obtained from the following components:
|Bed topography||(Bamber 2001) + Bathymetry(Jakobsson et al. 2008)||netCDF, CF 1.3. Polar Stereographic projection, 5 km||bedrock_altitude||meter|
|Ice thickness||Bamber (2001)||netCDF, CF 1.3. Polar Stereographic projection, 5 km||land_ice_thickness||meter|
|Surface elevation||Bamber (2001)||netCDF, CF 1.3. Polar Stereographic projection, 5 km||surface_altitude||meter|
|Basal Heat Flux||Shapiro and Ritzwoller(2004)||netCDF, CF 1.3 Polar Sterographic projection, 5km Please note that for the purposes of SeaRISE, GTHF should be capped at a value of -0.07 w/m^2, and the field provided in the netCDF file does not include these updated values||basal_heat_flux||watts/meters^2|
|Temperature time series||GRIP for 125kyr, interpolated over 100 year intervals||Text file||N/A||degrees Celsius|
|Sea Level Change||SPECMAP||Text file, also in NetCDF||N/A||meter|
|Mean Annual Temperature||Calculated from a paper on present day parameterization for present-day Greenland (Fausto et al 2009), it has dependencies on latitude, longitude and altitude.|| Fausto et al

|This is a composite map that averages all the data
we have from 5 years of observations (2000,2005-2008). In some sense its an average, but at any given point some years could be missing and the data are weighted by their individual errors. This may lead to artifacts if, for example, part of a fast changing glacier is covered with the data from one period and part with data from another (user beware). So things like changing speeds on outlet glaciers are somewhat ambiguous with respect to time, but are representative of early 21st speeds. The data also have not yet been rigorously screened for errors, and a few very bad points may exist. Updated versions will be available in the future.
