  2. 1. GPS Measurements of Atmospheric Water Vapour in a Low-Latitude Region

    Author : Surat Pramualsakdikul; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Signals at radio frequencies are distorted while travelling from a constellation of GPS satellites through the atmosphere. These signals can be used to estimate the amount of integrated precipitable water vapour (IPWV).There are advantages over other conventional techniques in terms of temporal and spatial resolution.

  4. 2. Global Navigation Satellite Systems: Applications With Time Scales From Seconds to Decades

    Author : Tong Ning; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; elevation dependent systematic effects; atmospheric integrated water vapour; Global Navigation Satellite Systems;

    Abstract : Global Navigation Satellite Systems (GNSS) can be used formany applications with time scales varying from seconds to decades.For~example, due to the ability of high-rate sampling, GNSStechniques are suitable for the detection of the large co-seismicdisplacements, which are dominated by low-frequency signals andtherefore can be recorded at a few Hertz and estimated with rathersmall uncertainty (millimetres).

  5. 3. GPS Meteorology: With Focus On Climate Application

    Author : Tong Ning; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Zenith Total Delay.; regional climate model; atmospheric Integrated Water Vapour; Global Positioning System;

    Abstract : The vital role of water vapour in the Earth’s climate system requires measurements of the atmospheric Integrated Water Vapour (IWV) with a long-term stability and a high accuracy. This work focuses on using the Global Positioning System (GPS) to provide IWV estimates for climate applications. READ MORE

  6. 4. Satellite microwave measurements of cloud ice properties

    Author : Bengt Rydberg; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; sub-mm; cirrus; upper troposphere; Odin; remote sensing; CloudSat; data retrieval;

    Abstract : Upper tropospheric cloud ice and water vapour are two intimately connected components of the atmosphere, that influence the Earth's energy budget. The response of these components to a warming climate is not well understood. READ MORE
