TL;DR: In this paper, the authors collected and analyzed precipitation samples along a south to north transect of the Tibetan Plateau, from Lhasa in the south, Nagqu and Tuotuohe in the middle, to Delingha in the north, from 2000 to 2003.

TL;DR: In this paper, the authors describe the climate of the coastal plains and the mountains in order to show that there is an area where the climate differs from those classified as BWn and BW in the Chilean Climate Classification.

TL;DR: In this paper, a stochastic three -parameter universal multifractal cascade model is used to model both the reflectivity and the minimum detectable signal of the radar to explain the same statistics to within 4.6% over the same range.

TL;DR: In this article, two concurrent approaches for estimating the Z-R relationship from DSD measurements are reviewed: (1) non-linear regression techniques on the scattergraphs of the (Z, R) pairs derived for each DSD spectra; (2) use of a DSD model fitting based on a scaling law formulation.

TL;DR: Meloni et al. as discussed by the authors focused on Saharan dust events detected until September 2006, characterized by large values of the Saharan Dust Event Index (SDEI), the sum of the daily average aerosol optical depth at 500nm, τ, over the duration of the dust episode.

TL;DR: In this article, the authors deal with air quality monitoring in an urban region of Kolkata, consisting of residential, commercial and industrial sites having high population density and pollution, and show that local emissions dominate the concentration of SO 2, NO 2, NH 3, and PM 10.

TL;DR: In this article, the authors measured concentrations of cluster ions and charged aerosol particles in the size range of 0.34-40nm and classified all days into one of seven classes according to the occurrence and type of new particle formation.
