Efficient high-resolution 3-D interpolation of meteorological variables for operational use

High Resolution Flow Modelling for Meteorological Purposes

This paper describes methods used in creation of a high-resolution mathematical model for describing flow in complex geometry areas. In the future it should be used mainly for airflow calculations in urban areas. In the second part we present some preliminary results of test experiments. At this stage, our model describes the 2D laminar incompressible flow but extension to full 3D approach is s...

Retrieving High Resolution 3-D Wind Vector Fields from Operational Radar Networks

High - Resolution 3 - D Refractive Index Imaging

This thesis presents a theory of 3-D imaging in partially coherent light under a non-paraxial condition. The transmission cross-coefficient (TCC) has been used to characterize partially coherent imaging in a 2D and 3-D paraxial model. It is shown that the 3-D TCC under the non-paraxial condition is an overlap integral of three hemispheres or 3-D pupil functions. By an inspection of the overlap ...

High Resolution Freehand 3 D Ultrasound

This paper describes a high resolution freehand 3D ultrasound system, whose accuracy surpasses that of previously documented systems. Such accuracy is achieved through a series of novel system design and calibration techniques. The accuracy is quantified using a purpose-built, tissue-mimicking phantom, designed to create idealised in vivo scanning conditions. The paper includes a thorough discu...

Compression Specification for Efficient Use of High Resolution Satellite Data

For an efficient usage and distribution of high resolution satellite images, several problems need to be solved. The issue comes with the increasing size of these data. Constraints are different than those of the on-board compression, thus different solutions can be selected. For on-board compression, the main constraints are the computational complexity and the rate attainable with qualified s...
