Six years of precise results in Oman 

Sixth and final year of Oman trial: once again, highly consistent enhancement, and very high probabilities around estimates

Australian Rain Technologies (ART) is pioneering statistical analysis to enable commercially effective decision-making in the area of rainfall enhancement. This statistical methodology is being applied to ART’s own ATLANT™ rainfall enhancement through ionisation technology. However it is equally applicable to chemical cloud-seeding, which has been hampered by inconclusive trial analysis for 70 years.

In particular the University of Wollongong has applied this analytical method across multiple trials of ART’s ATLANT™ ’ rainfall enhancement through ionisation technology over 10 years in Australia and Oman. (See summary in section on Statistical Methodology and full description of methodology in trial reports in Resources).

In all cases rainfall enhancement was identified at high levels of statistical confidence. Enhancement ranged from 10 per cent (90 per cent statistical confidence level) in three trials in South Australia to 16.3 per cent enhancement with 99.99 per cent statistical confidence level) in six trials in Oman. This is the sixth consecutive year that has returned an estimated enhancement effect of 15 per cent or more, with statistical probabilities greater than 99 per cent in Oman.

These figures are perhaps more usefully presented as there was a 99.5 per cent probability that enhancement was more than 10 per cent in Oman 2013-2016.

Such results, if repeated in multiple locations throughout the world, would represent a major complement to current expensive and in some ways unpalatable water supply augmentation methodologies.

They would add to water supplies at below 10 cents KL, $100 ML or $100,000 GL.

We have spent 10 years putting together a world-leading spatial statistical and econometric evaluation team as we pursued our path to rigorous demonstration of efficacy. We have learnt from 70 years of frustrating and often contradictory traditional weather modification trials since World War II.

We hope this website leads you to share our keen appetite for providing applicable results from rainfall enhancement trials. And for investigating ATLANT™’s potential in all areas of water shortage around the world.

Fact sheet:

Australian Rain Technologies and the ATLANT technology

• The ATLANT technology introduces ionized aerosols into clouds, accelerating the collision of cloud droplets and the formation of rainfall sized droplets.

• Ionisation is entirely harmless to humans and vegetation. Its sole impact on the atmosphere is to enhance rainfall. If severe weather is forecast the ATLANTTM units can be turned off to avoid any worsening of such conditions.

• In conjunction with the National Institute of Applied Statistical Research at University of Wollongong ART has developed a pioneering statistical methodology to determine the level of rainfall enhancement. This is a world first and follows 70 years of indeterminate statistical analysis of chemical cloud seeding trials. The methodology and results have been published in peer-reviewed journals.

• Three years of trials in Adelaide showed 10 per cent enhancement with a statistical probability of enhancement of 90 per cent.

• Analysis of six years of ionization trials in Oman has shown enhancement of 18 per cent with a statistical probability of enhancement of 99.9 per cent.

• Each unit covers more than 2,000 sq km and produces an additional 15-30 GL of usable water (dependent on measured local enhancement and underlying annual rainfall).

• At a cost of $750,000 p.a. a unit, this works out at $40,000-$60,000 GL ($40-60 ML), a very small fraction of other water options. A 50-unit Atlant application would deliver 1000GL at a cost of $37.5mn,

• Additional rainfall falls on pasture and forests before increasing soil water content and running off into rivers and dams. This proportionately increases pasture and tree growth.

• There will also be a proportionate increase in carbon uptake by such vegetation. A 50-unit installation in eastern Victoria might sequester an additional 6.4 million tons at a cost of $6 a ton. Expanded nationally, such installations could contribute a significant portion of Australia’s targeted reduction in CO2 emissions

• The Atlant Technology runs continuously (outside extreme weather events), consuming no more power than a television set.

• Flexible operations by remote control.

• Low-cost installation and easily relocated. Virtually zero-cost operation.

• Trial analyses and statistical methodology have been published in peer-reviewed scientific journals.
