  1. 1. Remote Sensing of Cryospheric Surfaces : Small Scale Surface Roughness Signatures in Satellite Altimetry Data

    University essay from Umeå universitet/Institutionen för fysik

    Author : Petter Ideström; [2023]
    Keywords : Remote sensing; Altimetry; Arctic; Cryosphere; ICESat-2; Cryosat-2; Svalbard;

    Abstract : The Arctic cryosphere is experiencing a higher rate of warming compared to the rest of the world due to Arctic amplification. As glacier elevation change provide reliable evidence of climate change it is routinely measured by satellite altimeters. READ MORE

  3. 2. Evaluation of high-resolution satellite precipitation products with ground-based measurements over Europe

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Svea Bertolatus; [2020]
    Keywords : Precipitation; satellite product evaluation; passive microwave; estimates; Europe; ground- based gauge data; Earth and Environmental Sciences;

    Abstract : Determining water quantity of precipitation, spatially and temporally is fundamental for weather forecasting, applications in hydrology and meteorology, climate science and for agriculture and industry. Only satellite measurements from space are able to perform large-scale measurements covering both, ocean and land. READ MORE

  4. 3. Ground validation and bias correction of GPM-IMERG V6 satellite precipitation product over Sweden

    University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Author : Mojtaba Moravej; [2020]
    Keywords : satellite precipitation product; bias correction; GPM-IMERG; Monte Carlo; evaluation; rain; Earth and Environmental Sciences;

    Abstract : This study attempts to assess and correct the performance of Integrated Multi-satellite Retrievals for Global Precipitation Measurement (GPM-IMERG) final run daily precipitation product across Sweden. The performance of GPM-IMERG version 6 final run was evaluated against 677 rain gauges in a period from 12 March 2014 to 31 May 2019. READ MORE

  5. 4. Estimating soil moisture from space - A comparison between soil moisture estimates based on satellite retrievals and the E-HYPE model under drought scenarios in France year 2003 and 2011

    University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Author : Erik Sönegård; [2017]
    Keywords : soil moisture; drought; hydrological modelling; satellite; E-HYPE model; ESA CCI SM; Copernicus SWI; Technology and Engineering; Earth and Environmental Sciences;

    Abstract : Economic impacts of drought events can amass to billions of Euros within the EU. Ways to estimate the amount of water in the soil is thus very valuable to gather information which could be used for decision making. This thesis looks at different ways to estimate the amount of water in the soil, the so called soil moisture. READ MORE

  6. 5. Human Influence on Marine Low-Level Clouds

    University essay from Institutionen för geovetenskaper; Uppsala universitet/Luft-, vatten- och landskapslära

    Author : Moa Sporre; [2009]
    Keywords : Low-level clouds; the indirect aerosol effect; satellite retrievals; cloud optical thickness; effective cloud droplet radius; Låga moln; den indirekta aerosol effekten; satellit observationer; molnoptisk tjocklek; effektiv molndroppsradie;

    Abstract : A study of air mass origin’s effect on marine stratus and stratocumulus clouds has been performed on clouds north of Scandinavia between 2000 and 2004. The aerosol number size distribution of the air masses has been obtained from measurements in northern Finland. READ MORE
