Flat panel displays (FPDs) have revolutionized modern technology by providing sleek, efficient, and high-performance screens for a wide range of applications. From televisions to smartphones and medical devices, FPDs are integral to everyday life. Today, flat panel displays are a standard in the electronics market, constantly pushing the boundaries of resolution, color accuracy, and power ...
In addition, with the rapid development of some other types of illuminated elements, for example, Organic EL as well as conventional LCD and PDP displays, there is a requirement for high-precision spectral radiation curve analysis. As a professional spectroradiometer supplier, RayClouds provides spectroradiometer for sale to meet your display measurements. ...
The Moderate Resolution Imaging Spectroradiometer or MODIS instrument captured a visible image of the remnants of Tropical Cyclone Kenneth as it continued to linger over the country and generate rainfall. ...
EDT (0755 UTC) on April 26, the Moderate Resolution Imaging Spectroradiometer or MODIS instrument aboard Aqua captured a visible image of Lorna. ...
In this study, the METRIC (mapping evapotranspiration at high resolution with internalized calibration) approach was evaluated using remotely sensed observations from the moderate resolution imaging spectroradiometer sensor and data from meteorological stations in the lower catchment of the Buyuk Menderes Basin in western Turkey in the form of actual ET maps at daily and monthly ...
A sub-pixel approach (algae pixel-growing algorithm) was used with 13 years of MOderate-resolution Imaging Spectroradiometer (MODIS) data to evaluate changes in bloom extension, initiation date, duration, and occurrence frequency before and after a massive bloom event (2007). ...
Currently collected snow cover data are considered using remotely sensed satellite observations, from moderate-resolution imaging spectroradiometer; but the results are inconclusive due to cloud. The strongest correlations between the NAO index and snow cover are found in eastern and southern Scotland; these results are supported by both SSGB and UKCP09 data. ...
This study investigates the water balance of the Yangtze River Basin (YRB) during 2003–2012 using the Tropical Rainfall Measuring Mission precipitation, the Moderate Resolution Imaging Spectroradiometer evapotranspiration and the Gravity Recovery and Climate Experiment total water storage change. ...
The AWiFS snow cover maps, based on the unsupervised classification method, were compared with the estimates of snow cover area derived from the moderate resolution imaging spectroradiometer (MODIS) images based on the normalized difference snow index. ...
ET estimates are also compared with the ET computed from a detailed distributed energy water balance model and with the ET product from the Moderate Resolution Imaging Spectroradiometer Global Evapotranspiration Project. These analyses are performed for the Upper Yangtze River basin (China) in the framework of NRSCC-ESA DRAGON-2 Programme. ...
Spectral variations associated with lamp operating conditions (e.g. cooling of the lamp), the angle of the spectroradiometer relative to the lamp when measuring the UV fluence rate, and the shape of the arc within the lamp are important to consider in order to achieve reproducible UV fluences when using a polychromatic collimated beam. ...
The spectral signatures were obtained in situ and in the laboratory using a portable high-resolution spectroradiometer (ASD FieldSpec 3). The prediction model generated showed high precision in the estimation of salinity in wastewater, a coefficient of determination of 89.6% and a low root mean square error of 0.12‰. ...
Therefore, this study evaluates the Moderate Resolution Imaging Spectroradiometer (MODIS) daily snow cover product in Central Asia. For the evaluation, in situ snow depth data from 30 meteorological stations and higher resolution Landsat data are used. ...
This study addresses various relational investigations among vegetation properties such as Normalized Difference Vegetation Index (NDVI), Leaf Area Index (LAI), surface temperature (TSK), and vegetation water content (VegWC) derived from satellite sensors such as Moderate Resolution Imaging Spectroradiometer (MODIS) and EOS Advanced Microwave Scanning Radiometer (AMSR-E). ...
The goal of this study was to assess the feasibility of using Tropical Rainfall Measuring Mission (TRMM) and Moderate Resolution Imaging Spectroradiometer (MODIS) products to drive a mesoscale hydrologic model (mHM) in a poorly gauged basin. ...
The future vegetation canopy information was projected by the monthly relationship between Terra MODIS (MODerate resolution Imaging Spectroradiometer) LAI (Leaf Area Index) and temperature. The future predicted LAI increased up to 1.9 in 2080s April and October because of the temperature increase 3.6°C and 5.3°C respectively. ...
This study evaluated the use of Moderate Resolution Imaging Spectroradiometer (MODIS) imagery in conjunction with directed soil sampling to assess and map soil salinity at a regional scale (i.e., 10–105 km2) in a parsimonious manner. ...
A decision-tree method classifies the distribution of crop fields in Asia using Terra Moderate Resolution Imaging Spectroradiometer (MODIS) and SPOT VEGETATION data, which include the NDVI and Land Surface Water Index (LSWI). ...
This study investigates the potential of 500-m MODIS (MODerate Resolution Imaging Spectroradiometer) data in estimating corn (Zea mays L.) and soybean [Glycine max (L.) ...
The photolysis frequencies were calculated using two different spectroradiometers to measure the actinic flux. In this paper we described the ozone date for the episode on 13 May 1998.Keywords: boundary conditions, carbon bond mechanism, emissions inventory, ozone episode, photolysis frequencies, radiosoundings, spectroradiometric measurements, urban airshed ...
