The Lena River Delta, Arctic Siberia: An Arctic Ground Day Observatory of the DUE Permafrost Remote Sensing Project
Abstract
Permafrost landscapes are a challenge for the validation of remote sensing products. The land surface is characterized by high heterogeneity, patterned ground, disturbances, abundance of small-sized water bodies, and sharp moisture gradients. A significant challenge in the evaluation of remote sensing products for high latitude permafrost landscapes are the very sparse ground data: there are only a limited number of well described and multi-instrumented field sites. Within the ESA Data User Element DUE PERMAFROST project an important component is the evaluation and the assessment by the users and remote sensing experts to lend confidence in the scientific utility of the DUE PERMAFROST products. The long-term and multi-instrumented Russian-German Samoylov Station in the Lena River Delta (Arctic Siberia) is a prime site for evaluation in DUE PERMAFROST PERMAFROST and serves as an important platform to answer the following questions: • Are plot data representative of surrounding parameters at satellite spatial resolutions? • How are the statistics derived from the matchup analysis against in-situ Diagnostic Data Sets (DDS) (absolute validation)? • How is the credibility of DUE Permafrost products against 'descriptive truth' (relative validation)?
