Vertical Profiles of Acetylene in the Troposphere and Stratosphere
Stratospheric measurements of acetylene up to altitudes of 30 km are presented. The air samples were collected during three different balloon flights, two of them at 44°N, one at nON using balloon borne, liquid neon-eooled, cryosamplers. Their acetylene concentration was measured in the laboratory by flame ionisation gaschromatography. The different profiles at nON and 44°N are discussed with r...
متن کاملStratosphere-troposphere Exchange
In the past, studies of stratosphere-troposphere exchange of mass and chemical species have mainly emphasized the synopticand small-scale mechanisms of exchange. This review, however, includes also the global-scale aspects of exchange, such as the transport across an isentropic surface (potential temperature about 380 K) that in the tropics lies just above the tropopause, near the 100-hPa press...
متن کاملAerosol measurements in the troposphere and stratosphere.
Light scattering measurements from a searchlight beam were carried out in New Mexico to determine the aerosol properties of the atmosphere. Although data were acquired to an altitude of about 70 km, the results show the aerosol attenuation parameters to be significant to about 35 km. The expression for the aerosol attenuation coefficient is derived based on the field geometry in conjunction wit...
متن کاملMean radiative energy balance and vertical mass fluxes in the equatorial upper troposphere and lower stratosphere
[1] We use radiative transfer calculations to quantify vertical mass transport in the equatorial upper troposphere (UT) and lower stratosphere (LS), employing high resolution sonde measurements of temperature, ozone and water vapor at seven equatorial locations (10 S–10 N). The influence of clouds is examined using data from the International Satellite Cloud Climatology Project (ISCCP) and the ...
متن کاملShear Turbulence: Onset and Structure
Figure 1: Reynolds’ 1883 experiment, still operating at the University of Manchester, UK. Water flows down a long pipe and ink is introduced at the pipe centerline. On the right are the original drawings showing the dye filament in laminar flow (a), and the rapid mixing of the dye and water when the Reynolds number is larger than about 2000 in (b). (c) shows details of vortical structures in tu...
