The Daedalus solution was to harvest the fuel from gas - giant planets like Jupiter, by building and operating a fleet of balloon - borne robotic extraction factories in their atmospheres.

Cosmic rays of modest energy are measured directly by sending detectors to heights above most of the earth's atmosphere, using high - flying balloons and satellites.

Case in point: his Work No. 202: Half the air in a given space, 1998, whose Robert Barry-esque ineffability (compare that artist's designation as works, in 1969, of quantities of inert gases released into the atmosphere) is belied by the infantine delight of seeing it embodied by thousands of party balloons.

``... China and India, face ballooning energy appetites, a finite atmosphere», Not sure what you mean by a finite atmosphere.

Using NOAA database of weather balloon observations Miskolczi was able to demonstrate that the IR transmittance of the atmosphere did not change for 61 years while carbon dioxide percentage increased by 21.6 percent.

Using NOAA database of weather balloon observations that goes back to 1948 he studied the absorption of infrared radiation by the atmosphere over time.

He used NOAA weather balloon database that goes back to 1948 to study the absorption of infrared radiation by the atmosphere over time.

In 2010 Miskolczi used NOAA database of weather balloon observations to study absorption of infrared radiation by the atmosphere.

Measurements by weather balloons, the main method used to measure temperatures at the time, only test a small sliver of the atmosphere and are far from comprehensive.

A radiosonde is a battery - powered telemetry instrument package carried into the atmosphere usually by a weather balloon that measures various atmospheric parameters and transmits them by radio to a ground receiver.

... X-rays are absorbed by Earth's atmosphere, such measurements are made above the atmosphere by apparatus carried by balloons, rockets, or orbiting satellites.

They are most commonly used by being lifted up through the atmosphere by a weather balloon — data sets compiled from parts of this data are often referred to as the «Balloon Record&balloon — data sets compiled from parts of this data are often referred to as the «Balloon Record&Balloon Record».

The chart above compares actual temperatures from the earth's bulk atmosphere as measured by satellites and weather balloons, to average theoretical temperatures from 102 model runs.

Data often cited by the anti forces generally turn out to be either statistical extrapolation, or they are using data that has been proven wrong (one weather monitoring station on a balloon was found to be too high in the atmosphere, giving cooler results then expected, same with a monitoring station in the ocean that was too deep).

Fine titanium dioxide particles transported into the upper atmosphere by giant balloons could help combat climate change, says a UK chemical engineer.

Using NOAA weather balloon database that goes back to 1948 he studied the absorption of infrared radiation by the atmosphere over time.

The intensity is proportional to the temperature of broad vertical layers of the atmosphere, as demonstrated by theory and direct comparisons with atmospheric temperatures from radiosonde (balloon) profiles.

The Spice team - drawn from a number of universities as well as Marshall Aerospace - calculates that 10 or 20 giant balloons at a 20 km altitude could release enough particles into the atmosphere to reduce the global temperature by around 2C.

No benefit for accidental death is payable if the Insured's death is caused or contributed to by: disease or infirmity of mind or body, or medical or surgical treatment for such disease or infirmity; an infection not occurring as a direct result or consequence of an accidental bodily injury; any attempt at suicide, or intentional self - inflicted injury, while sane or insane; travel in an aircraft or device used for testing or experimental purposes, used by or for military authority or used for travel beyond the earth's atmosphere; active participation in a riot or insurrection; committing or attempting to commit a felony; intoxication as defined by the jurisdiction where the accidental injury occurred; riding or driving an air, land or water vehicle in a race, speed or endurance contest; rock or mountain climbing; bungee jumping; or aeronautics (hang - gliding, skydiving, parachuting, ultralight, soaring, ballooning and parasailing).
