Satellite remote sensing of terrestrial net primary production for the pan-Arctic basin and
Abstract. We applied a terrestrial net primary production (NPP) model driven by satellite remote sensing observations of vegetation properties and daily surface meteorology from a regional weather forecast model to assess NPP spatial and temporal variability for the pan-Arctic basin and Alaska from...
