  1. 16. Estimation of Evapotranspiration through remote sensing. Comparison between three different resolution sensors at Barrax field, Spain.

    University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Author : John Diego Sierra Torres; [2008]
    Keywords : geomorphology; Physical geography; Evapotranspiration and semote sensing; S-SEBI Model; Water balance; Environmental Satellite images applications; Environmental studies; Miljöstudier; Natural science; climatology; cartography; Naturvetenskap; Hydrogeology; geographical and geological engineering; Hydrogeologi; teknisk geografi; teknisk geologi; pedology; Fysisk geografi; geomorfologi; marklära; kartografi; klimatologi; Earth and Environmental Sciences;

    Abstract : Nowadays importance of water balance regarding measurements and water cycle pathways are of prime interest in a new perspective. Global issues, like Earth warming, or regional planned uses of water, e.g. irrigation, demand an increase in accuracy and coverage of different components of the water balance. READ MORE

  3. 17. Validation of Remote Sensing Snow Cover Analysis

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

    Author : Anna Geidne; [2005]
    Keywords : snow cover products; validation satellite observations; NESDIS; MSG images;

    Abstract : The by SMHI (Swedish Meteorological and Hydrological Institute) developed snow cover product, that analyses snow cover from satellite images, needs to be validated. A reliable validation method should be developed and concentrated to verify the snow cover analyses from images emerged from the recently operative European MSG-satellite. READ MORE

  4. 18. Analysing environmental change in semi-arid areas in Kordofan, Sudan

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Tobias Hinderson; [2004]
    Keywords : naurgeografi; climatology; cartography; desertification; vegetation pattern; physical geography; Sahara; pedology; geomorphology; geomorfologi; marklära; kartografi; klimatologi; Earth and Environmental Sciences;

    Abstract : Forskning har visat på en trendökning i NOAA NDVI för Sahelområdet under perioden 1982-1999. Dessa observationer kan indikera att vegetationsmängden i området är ökande. Förändringen kan tolkas som en återhämtning från torkan som drabbade området under 1970- och 1980-talen. READ MORE

  5. 19. Investigating vegetation changes in the African Sahel 1982-2002 : a comparative analysis using Landsat, MODIS and AVHRR remote sensing data

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Martin Sjöström; [2004]
    Keywords : marklära; desertification; semi-arid; Sahara; physical geography; geomorphology; pedology; cartography; climatology; geomorfologi; naturgeografi; kartografi; klimatologi; Earth and Environmental Sciences;

    Abstract : There has been much debate concerning the concept of degradation and desertification in semi-arid lands, in particular semi-arid Sub-Saharan Africa, during the last two decades. However, recent findings suggest a consistent trend of increasing satellite-derived vegetation greenness in much of the African Sahel as interpreted from Pathfinder Advanced Very High Resolution Radiometer (AVHRR) Normalized Difference Vegetation Index (NDVI) data for the period 1982-1999.

  6. 20. The usefulness of coarse resolution satellite sensor data for identification of biomes in Kenya

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Lova Cronquist; Sofia Elg; [2000]
    Keywords : geomorphology; physical geography; mapping; remote sensing; climate models; vegetation monitoring; seasonal dynamics; pedology; cartography; climatology; naturgeografi; geomorfologi; marklära; kartografi; klimatologi; Earth and Environmental Sciences;

    Abstract : Vegetation phenology (seasonal rhythm) is closely related to seasonal dynamics in the lower atmosphere and is therefore an important element in global climatic models and vegetation monitoring. Remote sensing is the primary means by which we can observe the dynamic characters of the earth's biosphere. READ MORE
