  1. 1. Spatial downscaling of gridded soil moisture products using optical and thermal satellite data: the effects of using different vegetation indices

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Tómas Halldórsson Alexander; [2023]
    Keywords : Physical Geography and Ecosystem Analysis; Remote Sensing; Soil moisture; Downscaling; Vegetation index; Earth and Environmental Sciences;

    Abstract : Soil moisture (SM) plays an important role in the exchange of heat and water between the surface and atmosphere, impacting water and energy cycles and the climate. Satellite remote sensing offers a global-scale estimation of SM; however, the coarse resolutions of satellite SM products, typically ranging from 25-50 km, are unsuitable for regional analysis.

  3. 2. Mesoscale precipitation systems in the Tibetan Plateau region as represented by global reanalysis, regional downscaling and satellite data between 2001 - 2016

    University essay from Göteborgs universitet/Institutionen för geovetenskaper

    Author : Benjamin Holmberg; [2022-09-01]
    Keywords : Tibetan Plateau; monsoon; westerlies; mesoscale; convection; precipitation; climate modelling; global reanalysis; regional downscaling; spatial resolution; re-initialization; spectral nudging; convective parameterization;

    Abstract : The Tibetan Plateau (TP) is one of the world’s most important water towers. Convective precipitation systems play an important role by providing freshwater for the highly densely populated downstream regions, but they can also cause hazardous floods. READ MORE

  4. 3. Modeling the effect of roads and topoclimate on plant invasions in mountains : the case of Trifolium repens

    University essay from SLU/Dept. of Ecology

    Author : Nina Roth; [2016]
    Keywords : non-native plants; alpine; roadsides; SDM; downscaling climate; management;

    Abstract : Non-native species are a main cause for the global loss of biodiversity and ecosystem services. Mountain regions have been relatively spared from plant invasions up to now, mostly due to climatic restrictions and low human influence, with roads being the main pathways. READ MORE

  5. 4. Regional Precipitation Study in Central America, Using the WRF Model

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

    Author : Tito Maldonado; [2012]
    Keywords : WRF; Central America; precipitation; dynamical downscaling; regional models; reanalysis; cumulus parameterization schemes.; WRF; Centralamerika; nederbörd; dynamiska nedskalning; regionala modeller; reanalys; cumulus parametrisering system;

    Abstract : Using the regional climate model WRF, and the NCEP-NCAR Reanalysis Project data asboundary and initial conditions, regional precipitation was estimated by means of thedynamical downscaling technique for two selected periods, January 2000 and September2007. These months show very particular climatic characteristics of the precipitationregimen in Central America, like dry (wet) conditions in the Pacific (Caribbean) coast of theCentral American isthmus, in January, and wet (dry) conditions, respectively in each coast,during September.
