The refractive index structure constant (Cn2) is a key parameter used in describing the influence of turbulence on laser transmissions atmosphere. Three different methods for estimating Cn2 were analyzed detail. A new method that uses combination these continuous profiling with both high temporal and spatial resolution proposed demonstrated. Under assumption Kolmogorov “2/3 law”, profile can be...

The validation of remote sensing products (RSPs) is fundamental work before the proper use of RSPs. This paper mainly introduces the technical specification for the validation of remote sensing product, which is used to guide user how to validate the available products. The validation of remote sensing products (VRSP) mainly there are two levels. The first level focuses on the validation at pix...

The sensible heat is an important component in surface energy partitioning over the land surface. This paper compared the sensible heat fluxes measured by a large aperture scintillometer system (LAS) and an eddy covariance system (EC) over a rice paddy with a patch of mulberry seedlings in the east China coastal region during the period from 13 September–11 October 2015. During the observation ...

We adapt a physically-based single-layer urban canopy model (UCM) to study the energy budget in urban areas. The energy budget scheme in this study is similar to the scheme implemented in the WRF-NOAH urban canopy model, but it is decoupled from the Weather Research and Forecasting (WRF) model. Simulations are carried out to quantify the sensitivity of the model to each atmospheric and surface ...

This work aims to quantify and improve the sensitivity of monocular passive ranging techniques in sequences that are degraded by the the quasi-periodic inter frame motion and localised blurring associated with atmospheric scintillation. Ranges from tens of meters up to 1km in uncontrolled outdoor conditions were investigated. This work has application in surveillance, border control, artillery,...

Land surface evapotranspiration (ET) derived from remote sensing data has significant meaning for plant growth monitoring, crop yield assessment, disaster monitoring and understanding energy and water cycle in river basin area and surrounding regions. In the study, we developed a land surface ET remote sensing retrieval system to estimate the daily ET in Shahe river basin using the TM\ETM+ imag...

The Laser Communications Relay Demonstration (LCRD) project will demonstrate high bandwidth space to ground bi-directional optical communications links between a geosynchronous satellite and two LCRD optical ground stations located in the southwestern United States. The project plans to operate for two years with a possible extension to five. Objectives of the demonstration include the developm...

فضای باز مدارس ازجمله فضاهای مهم آن‌ها و محل فعالیت‌هایی چون بازی آموزش است دانش‌آموزان مهارت‌های تحصیلی، محیطی، اجتماعی را در آن می‌آموزند، بنابراین باید تابع مشخصاتی خاص پاسخ‌گوی همۀ نیازهای باشد. اینکه آسایش حرارتی از اساسی‌ترین نیاز برای حضور حیاط است، تأمین ضروری می‌نمایاند. تعیین محدودۀ امری پیچیده مشابه، بسته به تنوع افراد، تجربیات، انتظارات، فرهنگ، سن، جنسیت آن‌ها، متفاوت است. پژوهش حاض...
