background; brucellosis (malta fever) is a major contagious zoonotic disease, with economic and public health importance. methods; to assess the effect of meteorological (temperature, rainfall, humidity, and wind) and climate parameters on incidence of brucellosis, brucellosis distribution and meteorological zoning maps of zanjan province were prepared using inverse distance weighting (idw) and...

background: measurement of gross , gross activities, and cosmogenic beryllium-7 (7be) concentrations were made both daily and weekly during the years 2001- 2004 from samples of atmospheric aerosols filtered from the air at tehran nuclear research center (35 41' n) and zahedan (28 29' n). materials and methods: weekly aerosol samples were collected with the high-volume air samplers on ...

In this paper Cramer-Rao lower bounds are presented on the estimation accuracy of any unbi-ased estimator of key polarimetric parameters in radar meteorology. The analysis is carried out by using a widely-accepted model for radar meteorology { the multivariate Gaussian model (Rayleigh fading) { along with the assumptions that the time series of horizontally and vertically polarized echoes are a...

Urban meteorology and pollution are characterised by a number of atmospheric parameters and their evolution in time, which all have specific problems as to their monitoring, representativeness, parameterisation and modelling compared to rural situations. The main goal of the Action COST-715 (1998-2004) was to provide the best guidance on how meteorology may be included in pollution calculations...

The physical environment affects and interacts with agroforestry systems through tree and crop growth, animal performance, management operations and interactions between the tree/shrub and non-tree components (abbreviated to tree/crop interactions). Interactions take place mainly through the media of microclimate, soil moisture and soil. They may have beneficial or adverse effects, for tree and...

New generation meteorological satellites carry infrared sensors able to sense the earth emission spectrum at very high spectral resolution. The related problems of cloud detection and inversion for geophysical parameters are addressed in this paper. © 2005 Optical Society of America OCIS codes: (010.3920) Meteorology; (010.7030) Troposphere
