Dataset Title Plant Functional Type map over Siberia derived from satellite observations
Dataset Purpose This new vegetation map provides a framework for further development of new Plant Functional Type (PFTs) in the ORCHIDEE model like shrubs, lichens and mosses, to represent the water and carbon cycles in northern latitudes better. Updated land cover data sets are critical for improving and maintaining the relevance of Earth system models for assessing climate and human impacts on biogeochemistry and biophysics.
Dataset Abstract PFTs maps for the ORCHIDEE land surface model at 1 km scale have been produced over Siberia. They are based on the land cover product GlobCover 2005 and an updated cross-walking approach to link land cover classes to the ORCHIDEE 16 PFT classes
Acquisition Methodology Land cover classification systems from GLC 2000, GlobCover 2005 and 2009, and MODIS collections 5 and 5.1 are first aggregated to a common legend, and then compared to high-resolution land cover classification systems, vegetation continuous fields (MODIS VCFs) and satellite-derived tree heights (to discriminate against sparse, shrub, and forest vegetation). The GlobCover data set, with a lower threshold for tree cover and taller tree heights and a better spatial resolution, tends to have better distributions of tree cover compared to high-resolution data. It has therefore been chosen to build new PFT maps for the ORCHIDEE land surface model at 1 km scale. Compared to the original PFT data set, the new PFT maps based on GlobCover 2005 and an updated cross-walking approach mainly differ in the characterization of forests and degree of tree cover. The partition of grasslands and bare soils now appears more realistic compared with ground truth data.

Description The PAGE21 consortium is be made up of leading European and international permafrost specialists, covering the entire spectrum of research from field studies, process studies, and remote sensing to global climate modeling. The consortium consists of 18 international partners from the following countries: Austria, Denmark, Germany, Finland, France, Great Britain, Island, Netherlands, Norway, Russian Federation and Sweden. PAGE21 will form the basis for accurate representation of permafrost-related processes in global climate projections, the lack of which has, until now, hampered assessments of the feedbacks of Arctic carbon pools to global climate change.
