Collaborative Research: Seasonality of circumpolar tundra - ocean and atmosphere controls and effects on energy and carbon budgets

The major research goal of this project is to characterize the seasonal linkages between land surface greenness and a suite of land, atmosphere and ocean measures in the context of Arctic tundra vegetation. We have analyzed the seasonality of Arctic sea ice concentrations, land surface temperatures and NDVI and how they have changed over the satellite record. These regional time series are provided in the data archive. We have investigated additional remote sensing data (e.g. snow), climate data (e.g. Reanalysis Data), WRF modeling, and ocean assimilation (heat content) information to advance our understanding of how and why the tundra is changing. This is a continuing project of 'Collaborative Research: Greening of the Arctic - Synthesis and Models to Examine the Effects of Climate, Sea-ice, and Terrain on Circumpolar Vegetation Change' (NSF ARC # 0531180).
