The rapid decline in the extent and health of coastal salt marshes has created a need for nondestructive methods for evaluating the condition of salt marsh ecosystems. This paper describes simultaneous uses of field sampling and remote sensing approaches to understand salt marsh ecosystem functions and species distributions and discusses the implications for salt marsh monitoring using remote s...

The increasing number of sensor types for terrestrial remote sensing has necessitated supplementary efforts to evaluate and standardize data from the different available sensors. In this study, we assess the potential use of IKONOS, ETM+, and SPOT HRVIR sensors for leaf area index (LAI) estimation in forest stands. In situ measurements of LAI in 28 coniferous and deciduous stands are compared t...

Several soiland atmospheric correcting variants of the normalized difference vegetation index (NDVI) have been proposed to improve its accuracy in estimating biophysical plant parameters. In this study, a sensitivity analyses, utilizing simulated and observational data, was conducted on the NDVI and improved variants by analyzing the atmospheric-and soilperturbed responses of each VI as a conti...

Abstract Rest-frame mid- to far-infrared (IR) spectroscopy is a powerful tool study how galaxies formed and evolved, because major part of their evolution occurs in heavily dust enshrouded environments, especially at the so-called Cosmic Noon ( $1< z < 3$ ). Using calibrations IR lines features, recently updated with Herschel Spitzer spectroscopy, we predict expected fluxes aim measure St...

Abstract The Valley of the Kings (KV) is a UNESCO world heritage site with more than thirty opened tombs. Since first tombs were constructed, at least 24 historical flash flood events has been identified, each which contributed to destruction and deterioration Recently, most these have damaged inundated after 1994 flood. In order understand Geo-environmental impact mainly past floods due intens...

برآورد زی‌توده گیاهی از متغیرهای کلیدی مورد نیاز برای درک سیستم­های زیست‌محیطی می­باشند. در این راستا و با هدف بررسی تغییرات زمانی تولید گیاهی در واحدهای مدیریتی مختلف در مرتع مرجن بروجن این تحقیق انجام شد. در این تحقیق سعی شد اثر دوره رویشی گیاه و در نتیجه اثر زمان در مدل برآورد تولید گیاهی از بین رود، در نتیجه مدلی ارائه شد که در تمام فصل رویش و برای زمان­هایی هم که نمونه زمینی در دست نبود دا...
