  1. 1. Optical Remote Measurements of Particles in Emission Gas Plumes

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandling

    Författare :Weihua Wang; [2017]
    Nyckelord :Absorption spectroscopy; Aerosol; DOAS; SOF; Temporal-spatial data analysis; 吸收光谱学; 气溶胶; 差分吸收光谱技术; 掩光通量测量法; 时空域数据分析;

    Sammanfattning : This project aims to use temporal and spatial data analysis to express the measured air pollutant concentrations as well as their relation with the aerosol traces, indicated by the intensity ratio (IR). The surveying were performed during a field campaign of several days of mobile optical remote sensing measurements in Tianjing city, China. LÄS MER

  2. 2. Ionospheric Disturbance on GNSS Receivers and other systems

    H-uppsats, Chalmers tekniska högskola/Institutionen för rymd- och geovetenskap

    Författare :Weihua Wang; [2015]
    Nyckelord :GPS signals; TEC; equatorial plasma irregularities;

    Sammanfattning : Equatorial ionospheric plasma irregularities are generated at the magneticequator areas after sunset due to plasma instabilities. Its impact on the GPS(Global Positioning System) signals, both amplitude and phase, often resultsin a degraded performance of the GPS receivers. LÄS MER
