Sentences with phrase «microwave radiation emitted»

Temperatures aloft can be measured in a number of ways, two of which are useful for climate monitoring: by radiosondes (balloon - borne instrument packages, including thermometers, released daily or twice daily at a network of observing stations throughout the world), and by satellite measurements of microwave radiation emitted by oxygen gas in the lower to mid-troposphere, taken with an instrument known as the Microwave Sounding Unit (MSU).5 The balloon measurements are taken at the same Greenwich mean times each day, whereas the times of day of the satellite measurements for a given location drift slowly with changes in the satellite orbits.

These images correspond to microwave radiation emitted from Earth's surface and can be related to soil moisture and ocean salinity.

The researchers used satellites to measure heat in the form of microwave radiation emitted by oxygen molecules in the atmosphere from 1979 to 2005.

The dosimeter can determine the level of free radicals by comparing the amount of microwave radiation emitted with the amount that is reflected.

Not exact matches

Cosmic background radiation — that amazing «first light» emitted when the Universe was only a few hundred thousand years old — exists mainly in the form of microwaves.
