Not exact matches

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.

This investigation also provides detailed information on the atmospheric structure of the thermosphere, the layer of the Earth's atmosphere directly above the mesosphere and below the exosphere, by comparing and helping to refine models based on de-orbit data.

Here we present a chronology for the deep part of the core (67.8 - 31.2 ka BP), which is based on stratigraphic matching to annual - layer - counted Greenland ice cores using globally well - mixed atmospheric methane.

Second, using measured atmospheric CO2 concentrations short circuits two layers of modeling which themselves are major sources of uncertainty, namely, estimating global emissions and, then, estimating the atmospheric CO2 concentrations (based on complex models of the global carbon cycle).

Based on the understanding of both the physical processes that control key climate feedbacks (see Section 8.6.3), and also the origin of inter-model differences in the simulation of feedbacks (see Section 8.6.2), the following climate characteristics appear to be particularly important: (i) for the water vapour and lapse rate feedbacks, the response of upper - tropospheric RH and lapse rate to interannual or decadal changes in climate; (ii) for cloud feedbacks, the response of boundary - layer clouds and anvil clouds to a change in surface or atmospheric conditions and the change in cloud radiative properties associated with a change in extratropical synoptic weather systems; (iii) for snow albedo feedbacks, the relationship between surface air temperature and snow melt over northern land areas during spring and (iv) for sea ice feedbacks, the simulation of sea ice thickness.
