In the present study, we used 27 precipitation average monthly data from synoptic, climatologic, rain-guage and evaporative stations located in Zayandeh-Rud river basin for the period of 1970-2014. Before interpolating, the missing data in the time series of each station was reconstructed by the normal ratio method. Also, for the data quality control, the Dickey-Fuller and Shapiro-Wilk tests we...

As a large number of small-scale PV plants have been deployed in distribution systems, generation forecasting such has recently gaining interest. Because the power mainly depends on weather conditions, it is important to accurately collect data for relevant sites enhance accuracy. However, do not often their own measuring apparatus get historical data, so they used datasets from relatively near...

drought monitoring is a fundamental component of drought risk management. it is normally performed using various drought indices that are effectively continuous functions of rainfall and other hydrometeorological variables. in many instances, drought indices are used for monitoring purposes. geostatistical methods allow the interpolation of spatially referenced data and the prediction of values...

In this study, a regionalization study was conducted with the L–Moments method in order to determine change of dissolved oxygen (DO) required sustain life aquatic organisms given return period and also consider effects all stations. Dissolved concentration data 20 meteorological stations for spring months were evaluated between 1995 2014 Sakarya Basin, Turkey. Firstly, Homogeneity Criterion (H1...

Mapping of geological variables in the Croatian part Pannonian Basin System (CPBS) is mostly based on small input datasets. In case analyzed hydrocarbon field "B", reservoir "K", due to complex structure and pronounced tectonics, interpretations are restricted several blocks, where each has very limited dataset. The porosity (19 data) permeability (18 were analyzed. applied interpolation method...

The objective of this work is to present an update to the daily precipitation gridded set developed by Xavier, King and Scanlon (2016), where the previous dataset is namely v2 and the new one is v2.1. The v2.1 gridded data uses 9,259 rain gauges relative to 3,630 in v2. We also extend the period of the gridded data by two years (v2.1 is from Jan/01/1980 to Dec/12/2015 while v2 is from Jan/01/19...

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) an...

Abstract An accurate analysis of spatial rainfall distribution is great importance for managing watershed water resources, in addition to giving support meteorological studies and agricultural planning. This work compares the performance two interpolation methods: Inverse distance weighted (IDW) Kriging, annual distribution. We use data state Rio Grande do Sul (Brazil) from 1961 2017. To determ...

Agricultural development in northern polar areas has potential as a result of global warming. Such expansion requires modern soil surveys and large-scale maps. In this study, the abandoned arable experimental field founded by I.G. Eichfeld one century ago Salekhard city (Russian Arctic), located circle, was investigated. Our aims were to assess nutritional properties their spatial variability. ...
