Abstract: The evolution of oxygen in a primitive terrestrial atmosphere from the dissociation of water vapor is determined from the production and dissipation of hydrogen. The temperature of the exosphere however is directly related ...

Abstract: The eddy diffusion coefficient Kyy has been calculated using LIMS data for the months of December 1978 and January and February 1979. Two methods have been used. The first implements the suggestion made by Tung (1987) to ...

Abstract: Real-time rainfall monitoring in Africa is of great practical importance for operational applications in hydrology and agriculture. Satellite data have been used in this context for many years because of the lack of surface ...

Abstract: Operational, real-time rainfall estimation on a daily timescale is potentially of great benefit for hydrological forecasting in African river basins. Sparseness of ground-based observations often means that only methodologies ...

Abstract: Numerical experiments and statistical analyses are conducted to determine the skill of different Lagrangian techniques for the construction of tracer distributions. High-resolution potential vorticity (PV) maps are calculated ...
