MODIS Protoflight Model, launched on-board the NASA EOS Terra spacecraft on December 18, 1999, has been in operation for more than two years, providing the science community calibrated data sets for the global studies of the land, oceans, and atmosphere. MODIS has 36 spectral bands, covering the spectral range from 412 to 14200 nm, and provides spatial resolutions of 0.25 km (2 bands), 0.5 km (...

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 ...

climate change is found to be the most important global issue in the 21st century, so to monitor its trend is of great importance. atmospheric general circulation models because of their large scale computational grid are not able to predict climatic parameters on a point scale, so small scale methods should be adapted. among downscaling methods, statistical methods are used as they are easy to...

با توجه به رشد بالای جمعیت در جهان و نیاز اطمینان از امنیت غذایی، افزایش تولید واحد سطح محصولات زراعی به‌منزلة راهبردی اساسی حل مسئلة تأمین غذا به‌شمار می‌رود. سوی دیگر، وجود محدودیت زیرکشت پایین‌بودن میانگین عملکرد برخی کشاورزی مانند گندم کشور، محصول می‌تواند راهکاری عملی پاسخ کشور محسوب شود. یکی مهم‌ترین بیماری‌های فوزاریوم است که، نقش پیش‌بینی این بیماری جلوگیری کاهش بهره‌وری محصول، مدل‌هایی...

Abstract This study explored the combined impacts of climate and land-use change on mini-hydropower generation in Kyambura watershed. The soil water assessment tool (SWAT) was used as a hydrological model whereas statistical downscaling (SDSM) to downscale meteorological data for watershed year 2050. results show that there will be an increase urban land by 11.89%, barren 25.78%, 0.49% reductio...
