Positive numbers for Ĉt2REDD display CO2 emissions to the atmosphere, negative numbers display CO2 reductions.
Although infill from various geological processes is one reason for Titan's relative deficiency of craters, atmospheric shielding also plays a role; it is estimated that Titan's atmosphere reduces the number of craters on its surface by a factor of two.
Positive (black) numbers represent emissions to the atmosphere; negative (red) numbers represent removals from the atmosphere (the sink function of forests).
They found a close relationship between the levels of dust in the atmosphere and the number of ice crystals.
The study shows warming of the atmosphere increases the number of times temperatures reach extreme levels and evaporates more water from the oceans.
Despite this repressive atmosphere, an increasing number of Egyptians, disillusioned with Nasser's socialist, secular government, were turning to the mosque for political answers.
Often, private haircutting parties are born when a salon client approaches her stylist with the whispered promise of a festive atmosphere, a guaranteed number of guests and cash under the table in return for reduced rates.
An observed warming trend of the ocean's waters more recently is consistent with similarly observed global warming of the atmosphere; a growing number of researchers have concluded that human activities are contributing to the warming trend, although the extent of this contribution is not yet known.
Meteor shower, temporary rise in the rate of meteor sightings, caused by the entry into Earth's atmosphere of a number of meteoroids (see meteor and meteoroid) at approximately the same place in the sky and the same time of year, traveling in parallel paths and apparently having a common origin.
Whistlers propagate through the ionosphere (the portion of the atmosphere where the number of ions is large enough to affect the propagation of radio waves; it begins at a height of about 50 km [30 miles] above the Earth's surface).
