متن کاملAcid rain: ionic correlations in the eastern United States, 1980-1981.
Hydrogen ions in precipitation are correlated much more closely with sulfate than with nitrate, whereas ammonium ions are correlated more closely with nitrate than with sulfate. Target loadings of 14 to 16 kilograms of wet sulfate deposition per hectare per year, instead of 20 as suggested hitherto, are probably necessary to produce average pH values of 4.6 to 4.7, the approximate boundary leve...
متن کاملStatistical Analysis of Rain Fade Slope
The fade slope is a stochastic parameter and varies with time. The probability distribution of fade slope can depend on attenuation, on the drop size distribution and therefore on the type of rain, and on the wind velocity perpendicular to the path. Furthermore, if several rain cells and/or different kinds of rain may be present, the fade slope is likely to decrease with path length, and theref...
متن کاملStatistical Analysis of Rain Fade Slope
An analysis is made of the measured distributions of the fade slope of rain attenuation, conditional for attenuation values, measured at Eindhoven University of Technology from the satellite Olympus. It is found that the distribution is similar for positive and negative fade slopes and independent of frequency in the range from 12 to 30 GHz. A distribution model for the conditional distribution...
متن کاملEvaluation of ionic pollutants of acid fog and rain using a factor analysis and back trajectories.
Fog and rain water samples were collected at the same time in the Akita Hachimantai mountain range in northern Japan from June to September in 1998 and 1999. The various ion concentrations in these samples were analyzed, and the fog droplet sizes were measured for each fog event. As the fog droplet size increased, the ion concentration decreased. The slope of log-log plots of the concentration ...
