  1. 36. Investigating the impact of ground reflectance on satellite estimates of forest leaf area index

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Per Persson; [2007]
    Keywords : physical geography; bladyteindex; LAI; markreflektans; ground reflectance; geography; naturgeografi; geografi; Earth and Environmental Sciences;

    Abstract : Ground reflectance of forests has been suggested as a main source weakening the strength of relationships using satellite reflectance to predict forest leaf area index (LAI), a key input variable in models of carbon balance and global circulation. In this project a radiative transfer model was used to simulate the influence of ground reflectance in forest canopy reflectance in twenty forest stands in Scania (Southern Sweden). READ MORE

  3. 37. Test of the Rossby Centre Regional Atmospheric Climate Model’s Land Surface Scheme

    University essay from Lunds universitet/Fysiska institutionen

    Author : Karolina Nilsson; [2006]
    Keywords : Latent och sensibelt värme i kimatmodeller; Rossby Center; SMHI; Regional atmosfärisk klimatmodell; Global energibalans; Latent and sensible heat; Global energy balance; Regional climate model; Rossby Centre; Physics and Astronomy;

    Abstract : There is an economic interest in the development of reliable climate models that can give us a good estimation of the present and future climate. Farmers, electricity- and insurance- companies are some of the clients that need long term (monthly) weather information from the Swedish Meteorological and Hydrological Institute (SMHI). READ MORE

  4. 38. Estimation of leaf area index in southern Sweden with optimal modelling and Landsat 7 ETM+Scene

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Pontus Olofsson; Richard Stenström; [2000]
    Keywords : cartography; pedology; geomorphology; physical geography; optical modelling; satellite imaging; remote sensing; leaf reflectance; climatology; naturgeografi; geomorfologi; marklära; kartografi; klimatologi; Earth and Environmental Sciences;

    Abstract : Canopy reflectance models are used as a means of estimating vegetation parameters and simulating reflectance signatures of vegetation surfaces. A forest canopy reflectance model is tested on deciduous forest collections in southern Sweden. READ MORE
