Precipitation and air temperature data, only, are often recorded at meteorological stations, with radiation beingmeasured at very few weather stations, especially in developing countries. Therefore there arises a need for suitablemodels to estimate solar radiation for a completion of data sets. This paper is about an evaluation of eight models foran estimation of daily solar radiation (Q) from ...

a rain gauge network should serve general as well as specific purposes such as water supply, hydropowergeneration, flood forecasting, irrigation, and flood control. the level of accuracy a network can achieve depends onthe number and locations of gauges in the network. in this study, a rain gauge network was designed for hormozganprovince in the south of iran. monthly rainfall totals from 124 r...

Global warming has become a major threat to life on the earth, and recognizing its impacts can definitely be useful in controlling mitigating adverse effects. In this study, time series variations air temperature indices (frost days, Tmin, Tmax, Tmean, Tminmin, Tmaxmax, Tsoil-min), De Martonne aridity index (IDM), total precipitation were investigated using long-term meteorological data (1960–2...

The effects of climate change on agricultural ecosystems are increasing, and droughts affect many regions. Drought has substantial ecological, social, economic consequences for the sustainability land. Many regions northern hemisphere have not experienced a high frequency meteorological in past. For understanding implications grassland, analysis long-term data provides key information relevant ...

the goal of this study was to estimate the sensitivity of reference evapotranspiration (et0) to changes in meteorological parameters in the caspian region. long-term meteorological data (1961-2008) were obtained from three synoptic meteorological stations. the region was primarily classified into three climatic zones, based on de martonne climate classification. the penman–monteith equation was...

in this paper, a new framework has been developed for compatibility analysis of predictive climatic variables distribution with reference evapotranspiration (eto) in probabilistic analysis of water requirement. initially, measured monthly meteorological data of four cities of iran including kerman, shiraz, ramsar and babolsar synoptic weather station recorded from 1961 to 2003 were considered b...

We introduce a compressed de Bruijn representation of lambda terms and define its bijections to standard representations. Our compressed terms facilitate derivation of size-proportionate ranking and unranking algorithms of lambda terms and their inferred simple types. We specify our algorithms as a literate Prolog program.
