The new IMERG and GSMaP-v6 satellite rainfall estimation (SRE) products from the Global Precipitation Monitoring (GPM) mission have been available since January 2015. With a finer grid box of 0.1◦, these products should provide more detailed information than their latest widely-adapted (relatively coarser spatial scale, 0.25◦) counterpart. Integrated Multi-satellitE Retrievals for GPM (IMERG) a...
خشکسالی پدیده ای پیچیده و مخاطره آمیز در کل جهان بهویژه ایران به شمار می آید. تعیین و پیشبینی شدت خشکسالی می تواند در مدیریت مخاطرات ناشی از آن مؤثر باشد. برای تعیین شدت خشکسالی از شاخصهایی استفاده شده که به دو دستۀ کلی شاخصهای هواشناسی و سنجش از دور تقسیم می شوند. مهم ترین شاخص هواشناسی، شاخص بارش استانداردشده (spi) و در شاخصهای سنجش از دور نیز، شاخصهای مستخرج از پوشش گیاهی (ndvi) و شاخ...
9 The objectives of this study were to estimate variance components, genetic 10 parameters, EBV, accuracies, and rankings for nine ultrasound and carcass traits in a 11 multibreed Angus-Brahman population using three genomic-polygenic models and one 12 polygenic model (PM). The genomic-polygenic models used the complete GeneSeek 13 GPF250k SNP set (GPM), top 5% SNP (GPMR1), and 5% SNP evenly sp...
1.Introduction Use of proxy satellite observations for improving the model states of divergence, humidity and temperature has gained considerable impetus in the past one decade. Various researchers (Donner, 1998,Heckley et al, 1990, Krishnamurti, 1990) have used the satellite derived rainfall and moisture fields ameliorating the spin up problem in the tropics. Physical initialization methods (P...
Rainfall-induced shallow landslides are one of the most frequent hazards on slanted terrains. Intense storms with high-intensity and long-duration rainfall have high potential to trigger rapidly moving soil masses due to changes in pore water pressure and seepage forces. Nevertheless, regardless of the intensity and/or duration of the rainfall, shallow landslides are influenced by antecedent so...
Precipitation is a critical driver of vegetation productivity and dynamics in dryland environments, especially areas with intense livestock farming. Availability access to accurate, reliable, timely rainfall data are essential for natural resources management, environmental monitoring, informing hydrological rainfall-runoff models. Gauged precipitation drylands often scarce, fragmented, low spa...
