  1. 1. Studies of the PMWE : Polar Mesosphere Winter Echoes

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

    Författare :Simon Persson; [2022]
    Nyckelord :Polar; Mesosphere; Winter; Echoes; ESRAD; Infrasound; PMWE; PMSE; Summer; Radar; VHF; MST; MLT; SPE; HSS; Solar; Wind; evanescent; viscosity; FCA; 42;

    Sammanfattning : This Master thesis examines a phenomenon that occurs in the upper polar atmosphere, namely, Polar Mesospheric Winter Echoes, or PMWEs. PMWEs are radar echoes observed by Very High Frequency Mesosphere Stratosphere Troposphere (VHF MST) radar, from altitudes of 60 to 76 km at 7 to 15 UT, in the winter months from the middle of September to the beginning of May.

    Nyckelord :satellite precipitation product; bias correction; GPM-IMERG; Monte Carlo; evaluation; rain; Earth and Environmental Sciences;

    Sammanfattning : 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. LÄS MER

  7. 5. Promenaders effekt på studiemotivation och koncentrationsförmåga under eftermiddagsstudier hos gymnasieelever  - en studie med single case experimental design

    Kandidat-uppsats, Uppsala universitet/Fysioterapi

    Författare :Hugo Eriksson; Jakob Engström; [2019]
    Nyckelord :single case design; concentration; motivation; physical activity; high school students.;

    Sammanfattning : Abstract Background/problem: That physical activity (PA) is important for good health and high quality of life is well known. PA also increases a person’s executive functions, ability to concentrate, solve problems and to learn. High school students (HSS) that lack motivation lose focus and are overrepresented as high school dropouts. LÄS MER
