Ancillary Data Sources:

Bathymetric Data: NGDC supplied the Terrainbase gridded dataset. We also gridded individual soundings from the NOS Soundings Database to create our own relief map.

Reynolds-Smith Extended Reconstructed Sea Surface Temperature (ERSST) from NCDC.

Sea Ice Concentration (primarily daily passes at 25km resolution) from passive microwave data at NSIDC.

Hourly meteorlogical data recorded at Nome was obtained from NCDC. This data was employed to estimate heat fluxes from buk formulae following the COARE 2.5 algorithm for sensible and latent, Reed (1977) for shortwave, and Berliand and Berliand (1952) for longwave radiation fluxes. Clear sky incident solar radiation values were obtained from the NCEP/NCAR Reanalysis.

Yukon river discharge values from USGS.
