The Central Asian arid zone is the largest non-territorial in world, so it particularly important to understand optical properties of aerosols this region. In paper, we validate MCD19A2 atmospheric aerosol depth (AOD) remote sensing data by using ground-based and measured data. To explore spatial temporal changes as well interannual variations seasonal variations, characterize distributions AOD...

abstract recent global warming has led to a change in the global hydrological cycle and an increase in extreme events such as flood and drought at the global and continental scales. however, at the regional scale, the magnitude of warming and the resulting changes in water resources are different from one region to another. unlike air temperature whose increase is evident throughout the world, ...

In order to improve the accuracy of grain production forecasting, this study proposed a new combination forecasting model, the model combined stepwise regression method with RBF neural network by assigning proper weights using inverse variance method. By comparing different criteria, the result indicates that the combination forecasting model is superior to other models. The performance of the ...

In this paper, we obtain the strong consistency and asymptotic distribution of the Theil-Sen estimator in simple linear regression models with arbitrary error distributions. We show that the Theil-Sen estimator is super-efficient when the error distribution is discontinuous and that its asymptotic distribution may or may not be normal when the error distribution is continuous. We give an exampl...

This paper identifies the salient factors that characterize the inequality income distribution for Romania. Data analysis is rigorously carried out using sophisticated techniques borrowed from classical statistics (Theil). Decomposition of the inequalities measured by the Theil index is also performed. This study relies on an exhaustive (11.1 million records for 2014) data-set for total persona...

In this paper, trend detection of wave parameters such as significant height, energy period, and power along the Italian seas was carried out. To purpose, time series in period 1979–2018 taken from global atmospheric reanalysis ERA-Interim by European Center for Medium-Range Weather Forecasts (ECMWF) were considered. Choosing a significance level equal to 90%, use Mann–Kendall test allowed esti...

The trend analysis of annual temperature (daily average) and total precipitation has been conducted for 14 stations located in the Aegean Region, Turkey. Sen, Spearman’s rho, Mann-Kendall test methods are used detection historical trends region. Pettitt is also implemented to find significance trend, while Theil-Sen approach applied detect change point(s) time series. Findings following study i...

The Mediterranean Basin, located in a transition zone between the temperate and rainy climate of central Europe arid North Africa, is considered major hotspot change, subject to water scarcity drought. In this work, dry wet spells have been analyzed Wadi Cheliff basin (Algeria) by means annual precipitation observed at 150 rain gauges period 1970–2018. particular, characteristics (frequency, du...
