In particular five sets of trials took place at sea using aerosol clouds and animals.

The other method, delivering an aerosol cloud of ricin, proved less successful.

Cars, buses, trucks, and other vehicles had crashed into buildings as the lethal aerosol cloud spread.

Another system tries to use light to detect aerosol clouds from miles away, but it cannot tell whether the clouds contain pathogens.

When the bomb is detonated a brownish aerosol cloud drifts away towards the target animals.

The resulting aerosol cloud is subjected to UV radiation to create ions.

The propellant provides the force to generate the aerosol cloud and is also the medium in which the active component must be suspended or dissolved.

Tracking Other Aerosols Clouds don't just happen.

It is an airborne system carried by a helicopter to detect man-made aerosol clouds containing biological and chemical agents at long range.

It is used as a hand-held spray or can be fired in canisters that heat up spewing out an aerosol cloud at a steady rate.

However, some operations were ineffective due to inefficient delivery systems, using disease-bearing insects rather than dispersing the agent as an aerosol cloud.

The primary purpose of Night Train was to study the penetration of an arctic inversion by a biological aerosol cloud.

These gases are usually fired in canisters (LACR) that heat up, producing an aerosol cloud at a steady rate.

The sub-munitions were clustered into an E38 cluster adapter and when used, would be dropped from 35,000 feet generating an aerosol cloud in the shape of an ellipse.

Using ground truth instrumentation, the Standoff Detection Technology Evaluation Facility has been shown to successfully contain a homogenous aerosol cloud.

Microbes might be spread, for example, as an aerosol cloud, but it is technically complex and dangerous to produce a concentrated aerosol that could infect thousands of people.

The portable condensed aerosol device is typically designed to disperse aerosol in a 360 spray pattern, forming a large aerosol cloud around the vicinity of the fire.

A spray of solvent is heated to relatively high temperatures (above 400 degrees Celsius), sprayed with high flow rates of nitrogen and the entire aerosol cloud is subjected to a corona discharge that creates ions.

Operation Dew I consisted of five separate trials from March 26, 1952 until April 21, 1952 that were designed to test the feasibility of maintaining a large aerosol cloud released offshore until it drifted over land, achieving a large area coverage.

The eruption of Mount Hudson in Chile in August 1991 also contributed to southern hemisphere ozone destruction, with measurements showing a sharp decrease in ozone levels at the tropopause when the aerosol clouds from Pinatubo and Hudson arrived.
