2. 1. Studies of Atmospheric Water Vapor Using the Global Positioning System

   Author : Ragne Emardson; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; troposphere; microwave radiometry; climatology; radiosondes; atmospheric water vapor; Global Positioning System; time series analysis; VLBI; space geodesy; GPS; Very Long Baseline Interferometry; meteorology; radio wave propagation; Kalman filtering;

   Abstract : Atmospheric water vapor is of fundamental interest in the Global Positioning System (GPS) and Very Long Baseline Interferometry (VLBI) techniques. These techniques are based on the timing of radio waves propagating through the atmosphere. READ MORE

4. 2. Description and Analysis of Data and Errors in GPS Meteorology

   Author : Borys Stoew; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; atmospheric water vapor; global positioning system; propagation delay; meteorology; ensemble assimilation; GPS;

   Abstract : This report presents the relation between remote sensing techniques used for estimation of atmospheric water vapor content, and numerical weather prediction. The thesis makes an overview of the methods for estimation of the zenith wet/total delay (ZWD/ZTD) for radio waves in the neutral atmosphere, and a statistical description of data in relation to the sampling problem for atmospheric water vapor.
