Consulting
Dr Robert Dahni is a meteorologist who has worked in the Australian Bureau of Meteorology for over 25 years. From weather forecasting, IT support in research and operations to software development for domestic and international projects, he has developed skills in the analysis and visualisation of meteorological data.
Spatial Weather Tools
Spatial Weather Tools is a collection of extensible components for the meteorological processing and spatial conversion of historical or real-time weather data. The tools can analyse and transform the weather data into spatial formats. For example, raw polar radar data from the Bureau of Meteorology can be processed to generate geo-referenced radar data, images, shapefiles or GML. Spatial Weather Tools is a product application of ITT Visual Information Solutions' Interactive Data Language (IDL).
Particle Tracking
Particle tracking is an investigation of the identification and tracking of targets in satellite or radar imagery, utilising John Crocker and Eric Week's Particle Tracking using IDL. Each image has been sectorised, contrast enhanced and filtered to locate the features (i.e. clouds or thunderstorms) to be tracked. Features are tracked from image to image with wind barbs or vectors plotted over the latest image to represent the recent motion of the clouds or the expected track of the thunderstorms.
Image Enhancement
Enhancements improve the viewing quality of satellite imagery because the human eye cannot discern as many gray shades as can be displayed in most types of satellite imagery. Enhancements can exaggerate minor shading differences or highlight features of interest. Image enhancements available include lightening, darkening, false colouring and contrast stretching.
Grid Visualiser
Grid Visualiser is a proof-of-concept, interactive desktop application for the analysis and visualisation of the National Center for Environmental Prediction (NCEP) Global operational Forecast System (GFS) High Resolution (0.5 degree) data available at http://nomad5.ncep.noaa.gov/ncep_data/.
Time Series Visualiser
Are you interested in a customised Time Series Visualiser to met your specific data analysis and visualisation requirements? Take a look at the features of a prototype IDL-based application for Interactive Multidimensional Analysis and Visualisation of Time Series Data. It can read one-minute meteorological data from automatic weather stations or high frequency financial time series data from the stock exchange.
