today climate change is one of the most important human concerns this fact affected human life in different ways .  one of the most important impacts of climate change is on crops yield so that change in temperature  regime  particularly maximum and minimum  temperatures  is noticeably change plants production . in this research , is considered to  impact of climate change on water requirement ...

in this study impact of climate change on operation of gorgan rud basin's dams was evaluated. in this regard temperature and precipitation of the basin for 2011-2035 periods were downscaled using sdsm model and cgcm3-a2 outputs. results showed that annual temperature would increase 0.05°c and annual precipitation would decrease about 4percent. to predict streamflow of the gorgan rud basin ...

Moderate Resolution Imaging Spectroradiometer (MODIS) is the keystone instrument for NASA’s EOS Terra and Aqua missions, designed to extend and improve heritage sensor measurements and data records of the land, oceans and atmosphere. The reflective solar bands (RSB) of MODIS covering wavelengths from 0.41 μm to 2.2 μm, are calibrated on-orbit using a solar diffuser (SD), with its on-orbit bi-di...

Background: Climate change is one of the most complex human challenges in future. One consequences climate exposure people to heat stress, especially outdoor environments. The aim this study was model changes trend stress environments coming decades context and global warming. Methods: Wet Bulb Globe Temperature (WBGT) index, Canadian Earth System Model (CanESM2), Statistical Down Scaling (SDSM...

two statistical downscaling models, the non-homogeneous hidden markov model (nhmm) and the statistical down–scaling model (sdsm) were used to generate future scenarios of both mean and extremes in the tarim river basin,which were based on nine combined scenarios including three general circulation models (gcms) (csiro30, echam5,and gfdl21) predictor sets and three special report on emission sce...

Perubahan iklim dapat mempengaruhi karakteristik hujan suatu wilayah dan berpengaruh terhadap pengelolaan sumber daya air. Pengelolaan air yang mempertimbangkan faktor perubahan membutuhkan data hasil proyeksi model iklim. Hujan rerata pada DAS bisa diperoleh dengan dua pendekatan. Pertama, melakukan downscaling untuk setiap stasiun hujan, kemudian menghitung (Thiessen A). Kedua, wilayah, lalu ...
