Barometric Pressure Data Collection
MHL records barometric pressure at 8 locations along the New South Wales coast, Tweed Heads, Yamba, Port Macquarie, Newcastle, Sydney, Jervis Bay, Tuross Heads and Eden.
The instrument data is sampled every 15 minutes and telemetered to MHL twice each day at 06:00 and 17:00 Hrs Australian Eastern Standard Time. The readings are accurate to typically ±0.2 HPa and are corrected for station altitude.
This data is recorded to allow the correction of water level data recorded by total pressure transducers and to provide barometric information to assist understanding of water levels associated with ocean storms.
IMPORTANT: This information has been recovered directly from automatic recording equipment and has not been quality controlled by MHL. It should not be used for any commercial purpose without the written consent of the Manly Hydraulics Laboratory Manager.
