Abstract The frequency and severity of climatic extremes is expected to escalate in the future primarily because increasing greenhouse gas concentrations atmosphere. This study aims assess impact climate change on extreme temperature precipitation scenarios using indices Kashmir Himalaya. analysis has been carried out for twenty-first century under different representative concentration pathway...
Evapotranspiration is sensitive to climate change. The main objective of this study was examine the response reference evapotranspiration (ET0) under various change scenarios using artificial neural networks and Canadian Earth System Model Second Generation (CanESM2). Hargreaves method used calculate ET0 for western, central, eastern parts Prince Edward Island their two input parameters: daily ...
Quantitative analysis of changes in Lhasa River runoff components was significant to local water resources management. This study constructed the spatial processes hydrology (SPHY) model Basin and optimized model’s parameters using hydrograph partitioning curves (HPC) method. The Basin’s precipitation temperature were forecasted for 2020 2100 statistical downscaling (SDSM) two scenarios from fi...
The analysis and visualization of weighted networks pose many challenges, which have led to the development of techniques for extracting the network’s backbone, a subgraph composed of only the most significant edges. Weighted edges are particularly common in bipartite projections (e.g. networks of coauthorship, co-attendance, co-sponsorship), which are often used as proxies for one-mode network...
MODIS has 20 reflective solar bands (RSB), covering the VIS, NIR, and SWIR spectral regions. They are calibrated onorbit using a solar diffuser (SD) panel, made of space-grade Spectralon. The SD bi-directional reflectance factor (BRF) was characterized pre-launch by the instrument vendor with reference to the NIST reflectance standard. Its on-orbit degradation is tracked by an on-board solar di...
Suomi NPP (National Polar-orbiting Partnership) satellite (http://npp.gsfc.nasa.gov/viirs.html) began to daily collect global data following its successful launch on October 28, 2011. The Visible Infrared Imaging Radiometer Suite (VIIRS) is a key NPP sensor. Similar to the design of the OLS, SeaWiFS and MODIS instruments, VIIRS has on-board calibration components including a solar diffuser (SD)...
This study aimed to forecast temperature variations in the western and southwestern part of Iran using a general circulation model artificial neural networks (ANN). The data included mean diurnal temperatures from synoptic stations, National Centers for Environmental Prediction/ Center Atmospheric Research (NCEP/NCAR) reanalysis data, outputs third-generation global climate model, Hadley Centre...
در دهههای گذشته، در نتیجهی فعالیتهای انسانی و طبیعی، میزان گازهای گلخانهای در نیوار افزایش یافته و در نتیجه، دمای کرهی زمین روند افزایشی را به خود گرفته است. افزایش دمای کرهی زمین به نوبهی خود، باعث تغییرات معنیداری در حیطههای مرتبط، به ویژه منابع آب و رواناب شده است، بنابراین، مطالعه و شبیه سازی تغییرات عناصر اقلیمی (به ویژه دما و بارش) میتواند در برنامهریزیهای مدیریت منابع...
