  1. 16. Improvement of the GPP estimations for Sudan using the evaporative fraction as water stress factor

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Maria Angela Dissegna; [2016]
    Nyckelord :semi-arid regions; light use efficiency models; evaporative fraction; gross primary production; Physical Geography and Ecosystem analysis; GEM; Earth and Environmental Sciences;

    Sammanfattning : Estimation of GPP in Sudan using the evaporative fraction as water stress factor The Gross Primary Production "GPP" quantifies the amount of carbon entering an ecosystem. It is an ecosystem service since it is a source of energy for all organisms and it is estimated to reduce atmospheric CO2 in about 123 Pg C per year at the global scale. LÄS MER

  3. 17. Automatic information extraction and prediction of karst rocky desertification in Puding using remote sensing data

    Kandidat-uppsats, Högskolan i Gävle/Samhällsbyggnad, GIS

    Författare :Guiwei Wang; [2016]
    Nyckelord :GIS; remote sensing; KRD; change detection; CA Markov prediction; Puding; China;

    Sammanfattning : Karst rocky desertification (KRD) is one kind of severe environmental problem existing in southwest of China. Reveal KRD condition is vital to solve the problem. LÄS MER

  4. 18. Measurement of the convective heat transfer with wind : Developing and testing an Earth Scaled Atmospheric Temperature Sensor

    Master-uppsats, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Philipp Wittmann; [2016]
    Nyckelord :Wind; ATS; heat transfer; air temperature sensor; atmospheric temperature sensor;

    Sammanfattning :    The HAbitability, Brine Irradiation and Temperature Package (HABIT) instrument of the ExoMars Surface Platform will investigate the present day habitability of Mars at the near surface environment. This instrument includes three Atmospheric Temperature Sensor's (ATS's) which are similar to the ones previously used on the Rover Environmental Monitoring Station (REMS) of the Mars Science Laboratory (MSL) rover, that has now been operating on Mars for more than four years.

  5. 19. Determination of an Optimum Sector Size for Plan Position Indicator Measurements using a Long Range Coherent Scanning Atmospheric Doppler LiDAR

    Magister-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Elliot Simon; [2015]
    Nyckelord :LiDAR; WindScanner; PPI; Sector Scan; Dual Doppler; Remote Sensing; Wind Measurement;

    Sammanfattning : As wind energy plants continue to grow in size and complexity, advanced measurement technologies such as scanning Doppler LiDAR are essential for assessing site conditions and prospecting new development areas.   The RUNE project was initiated to determine best practices for the use of scanning LiDARs in resource assessments for near shore wind farms.

  7. 20. Normalization of Remote Sensing Imagery for Automatic Information Extraction

    Uppsats för yrkesexamina på avancerad nivå, KTH/Kommunikationsteori

    Författare :Pol del Aguila Pla; [2014]
    Nyckelord :;

    Sammanfattning : For the time being, Remote Sensing automatized techniques are conventionally designed to be used exclusively on data captured by aparticular sensor system. This convention was only adopted after evidence suggested that, in the field, algorithms that yield great resultson data from one specific satellite or sensor, tend to underachieve on data from similar sensors.
