  1. 1. Correcting biological infrared spectroscopy data for atmospheric gases and Mie scattering

    University essay from Lunds universitet/Beräkningsbiologi och biologisk fysik

    Author : Stéphan Pissot; [2020]
    Keywords : FTIR; spectroscopy; chemometrics; infrared absorption microscopy; atmospheric correction; scattering correction; Physics and Astronomy;

    Abstract : Infrared absorption microscopy is a powerful chemometric tool with a wide variety of applications. It is, however, subject to considerable disturbances from atmospheric gases and scattering effects. READ MORE

  2. 2. Ashish Vivekar (2020) Evaluation of methodology for estimating crop yield from multispectral UAV images : a case study at Lönnstorp, Sweden

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Ashish Vivekar; [2020]
    Keywords : Physical Geography and Ecosystem analysis; Multispectral Sensor; Radiometric Correction; Reflection calibration; Phenology; GEM; Earth and Environmental Sciences;

    Abstract : Adaptation of modern Unmanned Aerial Vehicle (UAV) and multispectral sensor technology in agriculture can enhance the capacity to accurately monitor crops. But these technologies come with its own set of challenges. READ MORE

  3. 3. ALTO Timing Calibration : Calibration of the ALTO detector array based on cosmic-ray simulations

    University essay from Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)

    Author : Sotirios-Ilias Tsivras; [2019]
    Keywords : ALTO; Cosmic-Rays; Water Cherenkov Detector; Python;

    Abstract : This thesis describes a timing calibration method for the detector array of the ALTO experiment. ALTO is a project currently at the prototype phase that aims to build a gamma-ray astronomical observatory at high-altitude in the Southern hemisphere. READ MORE

  4. 4. Energy balance closure, water balance, carbon exchange, and water use efficiency : observed and modeled outcomes for a managed, hemiboreal forest in Southern Sweden

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Linsey Marie Avila; [2019]
    Keywords : Energy balance; energy balance closure; energy balance ratio; net radiation; sensible heat; latent heat; turbulent fluxes; ground heat flux; energy storage; available energy; Bowen ratio; evaporative fraction; latent heat of vaporization; water balance; evapotranspiration; precipitation; water storage; water discharge; gross primary production; ecosystem respiration; net ecosystem production; carbon exchange; water use efficiency; Earth and Environmental Sciences;

    Abstract : The claims for the potential of boreal and sub-boreal forests to combat negative effects of climate change have been substantial with over half of Earth’s primary forests found within boreal and temperate regions of the Northern Hemisphere. Given the likely occurrence of more extreme climate events in the future, ascertaining a better understanding of how climate effects, such as profound fluctuations in precipitation, decreases in yearly snow, faster snow melt rates, variability in evapotranspiration due to environmental stress, and related changes in the energy, hydrological, and carbon cycles will change these northern, boreal landscapes is crucial.

  5. 5. Development of a multi-collector inductively coupled plasma massspectrometry method for measurement of stable sulphur isotope ratios in aerosol sulphate

    University essay from Uppsala universitet/Analytisk kemi

    Author : Katerina Rodiouchkina; [2018]
    Keywords : Sulphate aerosol; isotope ratio; sulphur isotope; δ34S and δ33S measurements; MC-ICP-MS; method development; inter-laboratory comparison;

    Abstract : Sulphur stable isotope ratios are useful tracers in geological and environmental studies. They can for example be used to trace the origin of atmospheric sulphate aerosols, because anthropogenic sulphate and natural sulphate have distinguishable δ34S-values (δ34S value of approximately +0 to +8 ‰ for anthropogenic and approximately +12 to +19 ‰ for natural).
