[1] An analytical algorithm for the determination of land surface temperature and soil moisture from the Tropical Rainfall Measuring Mission/Microwave Imager (TRMM/TMI) remote sensing data has been developed in this study. The error analyses indicate that the uncertainties of the enrolled parameters will not cause serious errors in the proposed algorithm. By applying the proposed algorithm to T...

In this study, ab initio atmospheric profiles generated through high-resolution calculations from the community weather model WRF, suitably matched up with both TRMM Microwave Imager (TMI) and Precipitation Radar (PR) instruments of the TRMM satellite were used to compute simulated brightness temperatures (BTs) corresponding to SAPHIR frequencies, through an in-house polarized radiative transfe...

The Earth Observing 1 (EO-1) mission is part of NASA’s New Millennium Program (NMP). The EO-1 Attitude Control System (ACS) flight software was based on the Tropical Rainfall Measuring Mission (TRMM) flight software, both of which were developed by the Hammers Company, Inc. Lessons learned during TRMM ACS software development led to a consolidated software development approach for the EO-1 ACS....

In this study, seven precipitation products (rain gauges, NEXRAD MPE, PERSIANN 0.25 degree, PERSIANN CCS-3hr, PERSIANN CCS-1hr, TRMM 3B42V7, and CMORPH) were used to force a physically-based distributed hydrologic model. The model was driven by these products to simulate the hydrologic response of a 1232 km watershed in the Guadalupe River basin, Texas. Storm events in 2007 were used to analyze...

Radical prostatectomy (RP) specimens with unfavorable pathol‐ ogy increased over nine years, but the reasons remain unclear, according to a study reported at the American Urological Asso‐ cia on (AUA) 2016 Annual Mee ng. Results were reported by Katherine Rotker, MD, of Brown University in Providence, RI. Following US Preven ve Health Services Task Force (USPSTF) 2009 and 2012 recommenda ons ag...

در قرن اخیر یکی از مهمترین چالش­‌های جهان، خشکسالی بوده، پایش و ارزیابی شدت و مدت آن برای مقابله و کاهش اثرات آن بسیار ضروری است. در چند دهه اخیر با توسعه و پیشرفت مباحث سنجش از دور، برآوردهای ماهواره­‌ای خشکسالی با دقت مکانی بالا و گام­‌های زمانی مختلف به‌طور گسترده مورد استفاده قرار گرفته است. لذا هدف پژوهش حاضر، تحلیل خشکسالی هواشناسی و توزیع خطای برآوردی داده­‌های ماهواره TRMM با داده‌­های ...

Availability of precipitation data at high spatial and temporal resolution is crucial for the understanding behaviors that are determinant environmental aspects such as hydrology, ecology, social like agriculture, food security, or health issues. This study evaluates performance 3B42-V7 satellite-based product on extreme estimates in China, by using Fuzzy C-Means algorithm L-moment-based region...

The Tropical Rainfall Measuring Mission (TRMM) satellite has been in operation for more than 7 years and providing distribution of rainfall throughout the Tropics using microwave observation from the Precipitation Radar (PR) and the TRMM Microwave Imager (TMI). PR, the first space-borne precipitation radar, provides height information based upon the time delay of the precipitation-backscattered...

In 2003, a network for hydrology of the semiarid region (REHISA in Portuguese) was created in Brazil. Since then, experimental watersheds in this region has been providing hydrometeorological data collected in automatic stations. However, the spatial distribution of these gauges might be insufficient to thoroughly understand the hydrological processes occurring in the area. Remotely sensed hydr...

Weed pressure in 1995 was incredible! What happened to produce such a glorious crop of weeds? The answer: drought! The Drought of 1995 and Weeds and Weed Control in 1996 Weed pressure in 1995 was, in a word, incredible! I toured many areas — golf courses, lawns, athletic fields, and institutional grounds — that were solid crabgrass, knotweed, clover, etc. In many of these areas, if there weren’...
