Analysis of terrestrial water storage changes from GRACE and GLDAS [PDF]

Water Resources Research, 2008
Since March 2002, the Gravity Recovery and Climate Experiment (GRACE) has provided first estimates of land water storage variations by monitoring the time‐variable component of Earth's gravity field. Here we characterize spatial‐temporal variations in terrestrial water storage changes (TWSC) from GRACE and compare them to those simulated with the ...

Determining Regional-Scale Groundwater Recharge with GRACE and GLDAS [PDF]

Remote Sensing, 2019
Groundwater recharge (GR) is a key component of regional and global water cycles and is a critical flux for water resource management. However, recharge estimates are difficult to obtain at regional scales due to the lack of an accurate measurement method.

Assessment of Runoff Components Simulated by GLDAS against UNH–GRDC Dataset at Global and Hemispheric Scales

Water (Switzerland), 2018
The current evaluations of global land data assimilation system (GLDAS) runoff were generally limited to the observation-rich areas. At the global and hemispheric scales, we assessed different runoff components performance of GLDAS (1.0 and 2.1) using ...

ارزیابی داده‌های تبخیر–تعرق، بارش و دمای هوای حاصل از مدل سطح زمین (GLDAS) با استفاده از داده‌های مشاهداتی در استان قزوین [PDF]

پژوهش‌های حفاظت آب و خاک, 2017
سابقه و هدف: کاهش ذخیره آب یک تهدید هیدرولوژیکی برای تولید محصولات کشاورزی و ثبات اجتماعی و اقتصادی در سراسر جهان به شمار می‌رود. در مناطق خشک و نیمه خشک نظیر کشور ایران که دارای بارش کم و تبخیر-تعرق زیاد می‌باشند این کاهش ذخیره آب به سرعت به آستانه خطر ...
