Sentences with phrase «microwave emissions»

They detect microwave emissions from oxygen molecules that vary in frequency with temperature.

All these sensors make measurements at critical frequencies at and above 85 gigahertz (GHz); sensors measure microwave emissions at 183 GHz, the signature frequency band emitted by water vapor, making it feasible to detect frozen hydrometeors (snow, ice, and the like) in the atmosphere.

Ocean surface temperatures are determined from ships and bouys, tied into satellite infrared measurements of ocean surface skin temperature, while MSU measurements use microwave emissions from the atmosphere, so that these measurements can be considered to be essentially independent.

What is more, because Jupiter's microwave emissions vary in wavelength based on the pressure (as well as temperature) of the atmospheric layers where they originate, observations at multiple wavelengths allow researchers to create a cross-section through the atmosphere.

The team observed specific microwave emission from hydrogen cyanide molecules (HCN) and formyl ions (HCO +).

To wit, Finkbeiner's 2003 detection of a haze of excess microwave emission near the galactic center in data from the Wilkinson Microwave Anisotropy Probe (WMAP) has not been fully accepted by Spergel and other members of the WMAP team.

The primary ways to monitor global average air temperatures are surface based thermometers (since the late 1800s), radiosondes (weather balloons, since about the 1950s), and satellites measuring microwave emissions (since 1979).

A silly example is it would be like a weatherman measuring the temperature of a neighboring city using microwave emissions from the oxygen above the city, and using that in their weather report.

They picked up the gas by its microwave emissions — suspecting that radiation from massive stars nearby had ionised the gas.

That will come later, with further close observations by Juno — not only with JunoCam but also its eight other instruments that can measure the planet's temperature, its magnetic and gravitational fields, microwave emissions from its deep interior, and more.

Furthermore, microwave emission from dust in our galaxy tends to be polarized, which could confuse BICEP - Keck observations, at least to some extent.

Instead, they measure microwave emissions.

``... using passive microwave data it is very easy to tell the difference between ice and water as the dielectric constant differs quite a bit and this is reflected in large differences in the microwave emission.

They estimate this temperature based on measurements of the microwave emissions of oxygen molecules in the atmosphere, which increase proportional to temperature.

Recognition that microwave emissions are causing much of this drought is non-existent in the media.

The instrument itself is a sensitive microwave receiver that detects the microwave emissions of the vapor and liquid water molecules in the atmosphere at two frequencies: 23.8 and 31.4 GHz.

«Satellites are not a thermometer in space, they're not making direct measurements of atmospheric temperature, they're measuring the microwave emissions from oxygen molecules,» Santer said.
