1. 1. Tracing water transport pathways in the coupled ocean-atmosphere system

   Författare :Dipanjan Dey; Kristofer Döös; Aitor Aldama Campino; David Ferreira; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Hydrological cycle; inter-ocean atmospheric water transport; water-mass conservation; atmospheric water trajectories; overturning water-mass stream functions; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography;

   Sammanfattning : Water is the most precious substance on the Earth and thus it is important to know how it moves around and is recycled.This knowledge will be useful to formulate educated future strategies about water usage in society and also to understand the near-surface salinity contrasts in the world ocean.

   Sammanfattning : This thesis deals with the evaluation of measurements of water vapor transport and sorption in wood. It mainly concerns measurements of the weight response of a sample after a step change in relative humidity. The thesis consists of an introduction and eight papers. The eight papers have the following contents: 1. LÄS MER

   Sammanfattning : 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. LÄS MER

7. 5. Sensing Atmospheric Water Vapor Using Radio Waves: Studies of the 2, 3 and 4-D Structure of the Atmospheric Water Vapor Using Ground-based Radio Techniques Comprising the Global Positioning System, Microwave Radiometry and Very Long Baseline Interferometry

   Författare :Lubomir Gradinarsky; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; microwave radiometry; global positioning system GPS ; water vapor; tomography; meteorology; propagation delay; delay gradients; climate;

   Sammanfattning : The radio wave propagation time, the primary observable in the geodetic techniques Global Positioning System (GPS) and Very Long Baseline Interferometry (VLBI) is affected by the presence of the atmospheric gases. By using appropriate modeling in the post-processing of the recorded phase measurements, together with local meteorological information, it is possible to estimate the total amount of atmospheric water vapor.
