the west of esfahan province, iran, is one of the most important agricultural areas throughout the country due to the climate variability and life-giving water of zayanderood river. rice is one of the major and economic crops in this area. the most important climatic elements in agricultural activities which should be considered include temperature, relative humidity, precipitation and wind. so...
The objective of this study is to estimate the daily extreme precipitation distribution in an Asian monsoon region considering orographic precipitation in mountainous areas. For this purpose, the APHRODITE data set and precipitation observations from 150 raingauges throughout Thailand were used as the main input. First, a bias-correction for underestimated precipitation in the APHRODITE data se...
Gridded climate products (GCPs) provide a potential source for representing weather in remote, poor quality or short-term observation regions. The accuracy of three long-term GCPs (Asian Precipitation—Highly-Resolved Observational Data Integration towards Evaluation of Water Resources: APHRODITE, Precipitation Estimation from Remotely Sensed Information using Artificial Neural Network-Climate D...
introduction there are significant differences in the spatial distribution of the iran annual precipitation. this is resulted from spatial behavior of precipitation in the one hand and variation in the sources of precipitation on the other. the lack of adequate distribution of meteorological stations and the unavailability of long-term statistics of precipitation makes the analysis of precipita...
In this research study the daily and annually trends of precipitation in the central Kavir basin of Iran during 1951- 2007. The pixel data of daily precipitation from APHRODITE’s data base with a spatial resolution of 0.25˚ have been used. The Mann-Kendall (MK) nonparametric test has been used for determining the precipitation trend in this area. The trends have been tested in 3 levels 90...
daily precipitation data from aphrodite's resources with a spatial resolution of 0.25*0.25 degree for 57 years have been used to detect the trend of precipitation in afghanistan. first of all, monthly, seasonally, and yearly maps and regional mean time series calculated. according to the annual map, mean annual precipitation of the country is about 256 mm. there are two precipitation maxim...
daily precipitation data from aphrodite's water resources with a spatial resolution of 0.25ëfor 57 years has been used to detect the trend of precipitation in azerbaijan republic. first of all monthly, seasonal and yearly maps and regional mean time series calculated. according to the annual map mean annual precipitation of the country is about 410 m.m there are two precipitation maximal ...
due to extraordinary large amount of information and daily sharp increasing claimant for ui benefits and because of serious constraint of financial barriers, the importance of handling fraud detection in order to discover, control and predict fraudulent claims is inevitable. we use the most appropriate data mining methodology, methods, techniques and tools to extract knowledge or insights from ...
We investigated the preformance of Asian Precipitation-Highly-Resolved Observational Data Integration Towards Evaluation (APHRODITE) water resources precipitation products in Bangladesh taking rain gauge data as reference for a 3-year period (2003-2005). Various statistical and categorical indices such coefficient correlation (CC), bias, relative bias (RB), mean absolute error (MAE), root squar...
drought is transient phenomenon , slow , repetitive and integral part of the climate of each region. drought begins with a substantial reduction in precipitation over the long-term average rainfall and over time, reduced soil moisture and surface and ground water resources will continue to decrease. this phenomenon is the most important in bakhtegan basin because of its importance in strategic ...
