Remote Sensing Methods
Remote Sensing of Polar Terrestrial Systems
Our aim is mapping of high-latitude vegetation, it's bio-physical quantities and actual changes by applying Remote Sensing at a wide range of spatial scales.
Data and methods:
- in-situ plant coverage, tree stand densities, steam and crown diameters, tree vitality status and LAI. See also Arctic Vegetation Analysis
- in-situ on chlorophyll, phytoplankton composition, cDOM, DOC. See also Arctic Lake Research
- in-situ field spectrometry: Buchhorn & Petereit (AWI-Workshop) developed a transportable field goniometer for bi-directional spectral measurements (BRDF) in harsh terrain (AWI-Patent DE10-2011117713.A1).
- satellite operational products from MODIS, MERIS, SENTINEL-3, optical satellite data from the Landsat, RapidEye and SENTINEL-2 satellite missions, SAR satellite data from the TDX and Sentinel-1 satellite missions (in cooperation with HGF-EDA, DLR and BGEO) and hyperspectral: AISA EAGLE airborne onboard AWI Polar-5, CHRIS-PROBA, EnMAP simulation (in cooperation with GFZ EnMAP).
- within the programmes of HGF-EDA, BMWi-EnMAP, FP7-PAGE21, ESA DUE Permafrost, ESA GlobPermafrost, BMBF-KoPf we undertake ground assessments for spatial upscaling to the satellite pixel scale. Within REKLIM we evaluate simulated variables from climate models such as HIRHAM using satellite products and in situ measurements.
