Abstract: The theory of condensation nucleation applied to radioactive fallout constituents shows that most tropospheric fallout particles are efficient nuclei in the production of warm rain. As a result it is found that the ...

Abstract: A covariance computer capable of accepting analog signals representing any two atmospheric variables is described. The instrument computes the covariance in a frequency band governed at high frequencies by the sensor ...

Abstract: Concentrations of radon daughters in falling rain have been used to derive precipitation scavenging rates of those particles with which radon daughters are associated; presumably these are the particulate component of ...

Abstract: Velocity variances in the convective boundary layer are examined using data derived in PBL experiments over land (Minnesota) and ocean (the Coral Sea) supported by data from the Kansas study of the surface boundary layer. ...

Abstract: Gradients of temperature and humidity above water surfaces are analyzed in order to determine the dependence of the long-term average Bowen ratios ? (the ratio of sensible to latent heat flux) on surface temperature. The ...

Abstract: ?Eddy accumulation? is a variation of standard eddy correlation techniques for determining eddy fluxes by sampling air in two separate systems depending on whether the vertical velocity is positive or negative. In concept, ...

Abstract: A system is described for the measurement of the atmospheric flux of water vapor near the surface, using a quartz-crystal oscillator as humidity sensor (as described by Gjessing et al.) and based on the Fluxatron technique. ...

Abstract: Radioactive fallout data suggest that the concentration of pollutants in rainfall, while highly variable, might be described on the average by about an inverse half-power dependence on the amount of precipitation. Recent ...
