This Bathurst NSW uranium grid geodetic is an airborne-derived radiometric uranium window countrate grid for the Bathurst NSW 1991 survey. The radiometric, or gamma-ray spectrometric method, measures the natural variations in the gamma-rays detected near the Earth's surface as the result of the natural radioactive decay of uranium (K), uranium (U) and uranium (Th). The data collected are processed via standard methods to ensure the response recorded is that due only to the rocks in the ground. The results produce datasets that can be interpreted to reveal the geological structure of the sub-surface. The processed data is checked for quality by GA geophysicists to ensure that the final data released by GA are fit-for-purpose. This Bathurst NSW uranium grid geodetic has a cell size of 0.0005 degrees (approximately 51m). The data are in units of counts per second (or cps). The data used to produce this grid was acquired in 1991 by the NSW Government, and consisted of 68244 line-kilometres of data at 250m line spacing and 80m terrain clearance.

A model to assess severe wind hazard using climate-simulated wind speeds have been developed at Geoscience Australia (Sanabria and Cechet, 2010a). The model has a num-ber of advantages over wind hazard calculated from observational data: Firstly the use of climate-simulated data makes it possible to assess wind hazard over a region rather than at a recording station. Secondly climate-simulated data allows wind analysts to calculate wind hazard over a long climatology and, more importantly, to consider the impact of cli-mate change on wind hazard. In this paper we discuss model sensitivity to two IPCC scenarios: scenario B1, a low emissions scenario, and scenario A2, a high emissions scenario. Current and future climate is considered. Currently we deal only with gusts associated with synoptic winds (mid-latitude weather systems) as the climate model only provides mean winds at a resolution of 14 km, which does not resolve thunderstorms. MODEL DESCRIPTION The model involves three computationally processes: - Calculation of return period (RP) for gust wind speed using a statistical model; - Extraction of wind speeds from a high resolution climate model; and - A Monte Carlo method to generate synthetic gust speeds based on a convolution of modelled mean speeds and empirical gust factor measurements.
