Previous analysis of Advanced Synthetic Aperture Radar (ASAR) signals collected by ESA’s Envisat has demonstrated a very valuable source of high-resolution information, namely, the line-of-sight velocity of the moving ...

A simple approach for estimating the equivalent diffusion for diagnosing tracer transport is proposed. Two different expressions are derived; one is based directly on an analytical solution of the two-dimensional ...

The present and future state of the Arctic sea ice cover is explored using new observations and a coupled one dimensional air–sea–ice model. Updated satellite observations of Fram Strait ice-area export show an increase ...

Detection, attribution and understanding of temperature changes in the high northern latitudes depend on constraining uncertainties and resolving apparent discrepancies in observational data sets. We quantitatively compare ...
