introduction temporal and spatial change of meteorological and environmental variables is very important. these changes can be predicted by numerical prediction models over time and in different locations and can be provided as spatial zoning maps with interpolation methods such as geostatistics (16, 6). but these maps are comparable to each other as visual, qualitative and univariate for a lim...

Land Surface Temperature (LST) is one of the most important physical and climatological  crucial yet variable parameter in environmental phenomena studies such as, soil moisture conditions, urban heat island, vegetation health, fire risk for forest areas and heats effects on human’s health. These studies need to land surface temperature with high spatial and temporal resolution. Remote sensing ...

in order to provide climatology atlas of frosts statistical properties of iran and to attain spatial and temporal pattern of it, daily data of minimum temperature of 62 synoptic weather stations for a 15 year-period (1991-2007) from october to may, were adopted from iran meteorological organization. by choosing may 1st as basis day, five statistical properties and their spatial and temporal dis...

Introduction Geographical situation of Iran is a place for interacting many physical and human processes which lead to specific precipitation climatology in the country. The month to month variation of precipitation is one of  the features which the precipitation climatology may reflect due to tempo - spatial characteristics. In fact, monthly distribution of precipitation is one of precipitati...

Water resources such as wetlands, in addition to their economic and social importance, are ecologically valuable sources of aquaculture production. Due to its effects on aquatic environments, necessity of monitoring and awareness of the spatial and temporal distribution of chlorophyll-a is important for environmental studies. In the new approach to such studies, application of spatial statistic...

In the present study, the main aim was the spatial evaluation summer rainfall of northwest of Iran based on30 stations in northwest of Iran during 30 years of statistical period (1985-2014). An attempt, using geo-statistical modeling by ordinary least squares (OLS) and geographically weighted regression (GWR) procedures, was also made. The results represented that the GWR model with higher S2, ...
