In December 2014 we upgraded our lightning network to the latest in sensor technology as used by the world's leading meteorological agencies. This has resulted in changes and improvements to the lightning data you will now see. The main changes are:
Distance and latitude/longitude coordinates are displayed when you mouse over the map. The origin for distance measuring is indicated by a red dot and defaults to either your location, if specified and in range, or the location of the radar/the centre of the map. The origin may be changed by clicking elsewhere on the map.
LocationEmerald Radar TypeDWSR 8502S 2° S-band Typical Availability24 hours
Geographical Situation: The radar is located on a gentle rise 9km east of Emerald township on Foley Rd, just off the Capricorn Highway. The radar is ideally sited to provide meteorological coverage for the surrounding area, with an almost unobstructed view in all directions.
Meteorological Aspects: The radar is well situated to monitor rain bearing weather systems that may affect the catchments and valleys of Lake Maraboon, the Nogoa river and Theresa Creek systems. Thunderstorms, rain bearing depressions, troughs and fronts will be able to be tracked and the distribution of rainfall produced by these systems can be monitored to provide valuable information for flood and severe weather warnings.
Non-meteorological aspects: In most cases the processing of the radar signal removes permanent echoes caused by obstructions such as hills, buildings and other solid objects. Occasionally, some permanent echoes will not be completely removed from the display. These echoes usually occur as isolated, stationary patches. In the Doppler wind product, road traffic on the Capricorn Highway may occasionally be noticeable near the radar.
