This paper introduces a potential method for the remote sensing of sea surface salinity (SSS) using the measured propagation delay of low-frequency Loran-C signals transmitted over an all-seawater path between the Sylt station...
A comparison of the relative effect of the Earth’s Quasi-D.C. and A.C. electric field on Gradient Drift Waves in large-scale plasma structures in the polar regions
Radio signals traversing polar-cap plasma patches and other large-scale plasma structures in polar regions are prone to scintillation. This implies that irregularities in electron concentration often form within such structures....

Meteorological Influence on eLoran Accuracy
Stringent accuracy requirements need to be met for eLoran deployment in marine navigation and harbour entrance and approach. A good accuracy model is therefore required to predict the positioning accuracy at the user’s receiver...

Technical note
The cloud overlap parameter α relates the combined cloud fraction between two altitude levels in a grid box to the cloud fraction as derived under the maximum and random overlap assumptions. In a number of published studies in...
A Ramsey characterisation of eventually periodic words
A factorisation $x = u_1 u_2 \cdots$ of an infinite word $x$ on alphabet $X$
is called `monochromatic', for a given colouring of the finite words $X^*$ on
alphabet $X$, if each $u_i$ is the same colour. Wojcik and Zamboni proved...
