Uncertainty analysis onto models and emission scenarios of climate change for projection of the temperature, precipitation, and evapotranspiration in the Neyshabour area [PDF]

open access: yesمخاطرات محیط طبیعی, 2018
Climate change is not only caused the rise in temperature but also changes in the global precipitation cycle, which leads to variation in spatial and temporal precipitation patterns. In this study, climate change impacts were investigated on temperature,
