برآورد دقیق رواناب یک عملیات محوری در زمینه مدیریت منابع آب محسوب می­‌شود و پیش­‌بینی آن برای بهره­‌برداری مطلوب از یک سامانه هیدرولوژیکی نقش مهمی دارد که معمولاً انجام این مهم با توسل به مدل‌­های مختلف هیدرولوژیکی صورت می­‌گیرد. محاسباتی مانند شدت و مدت که برای بارش متداول است، در بیشتر نقاط جهان، برای تعیین خصوصیات کلی بارش کافی نمی­باشند، زیرا محاسبات بارش از روی مشاهدات زمینی به‌صورت نقطه‌­ا...

Over the last five decades, Pakistan experienced its worst drought from 1998 to 2002 and flood in 2010. This study determined record-breaking impacts of droughts (1998–2002) (2010) analyzed given 12-year period, especially follow-on period when winter wheat crop was grown. We identified drought, flood, warm cold edges over plain Punjab based on a time series (2003–2014), using vegetation temper...

This study is designed to demonstrate use of free remote sensing data to analyze response of water resources and grassland vegetation to a climate change induced prolonged drought in a sparsely gauged semi-arid region. Water resource changes over Hulun Lake region derived from monthly Gravity Recovery and Climate Experiment (GRACE) and Tropical Rainfall Measuring Mission (TRMM) products were an...

This paper presents a new ocean wind vector measurement technique that uses the combined passive and active microwave measurements respectively from the Tropical Rainfall Measuring Mission (TRMM) Microwave Imager (TMI) and the Precipitation Radar (PR). The wind speed is inferred by TMI over a wide swath that includes the narrower PR swath. The PR scans cross-track ± 18°; and near the swath edge...

This study analyzes 15 years of Tropical Rainfall Measuring Mission (TRMM) satellite data, together with surface observations of thunderstorms and visibility, to study trends and relationships between aerosols and thunderstorms in southeast China. TRMM data used are from the lightning imaging sensor (LIS) and the precipitation radar (PR). Surface data are human-observed thunderstormoccurrence a...

The Tropical Rainfall Measuring Mission (TRMM) satellite is a joint US-Japanese mission to explore tropical rainfall and its effects on the earth's energy budget, general circulation, and climate. In the present study, a method has been developed here for rainfall retrieval over Indian land and oceanic regions from remotely sensed microwave (MW) brightness temperature (BT) data obtained from th...
