Article
Full-text available
Linear contrail coverage, optical property, and radiative forcing data over the Northern Hemisphere (NH) are derived from a year (2012) of Terra and Aqua Moderate-resolution Imaging Spectroradiometer (MODIS) imagery and compared with previously published 2006 results (Duda et al., 2013; Bedka et al., 2013; Spangenberg et al., 2013) using a consiste...

Article
Full-text available
Surface skin temperature (Ts) is an important parameter for characterizing the energy exchange at the ground/water–atmosphere interface. The Satellite ClOud and Radiation Property retrieval System (SatCORPS) employs a single-channel thermal-infrared (TIR) method to retrieve Ts over clear-sky land and ocean surfaces from data taken by geostationary...

Surface skin temperature (Ts) is an important parameter for characterizing the energy exchange at the ground/water-atmosphere interface. The Satellite ClOud and Radiation Property retrieval System (SatCORPS) employs a single-channel thermal-infrared- (TIR-) method to retrieve Ts over clear-sky land and ocean surfaces from data taken by geostationar...
Article
Full-text available
Monitoring and adjusting calibrations of various satellite imagers is often exacerbated by differences in their spectral response functions (SRFs). To help account for spectral disparities among satellite imagers, a web-based spectral band difference correction calculator has been developed to characterize the relationship between a specified pair...
Article
Full-text available
The properties of contrail cirrus clouds are retrieved through analysis of Terra and Aqua Moderate Resolution Imaging Spectroradiometer data for 21 cases of spreading linear contrails. For these cases, contrail cirrus enhanced the linear contrail coverage by factors of 2.4–7.6 depending on the contrail mask sensitivity. In dense air traffic areas,...
Article
[1] A modified automated contrail detection algorithm (CDA) using five infrared channels available from the Moderate Resolution Imaging Spectrometer onboard the Aqua satellite is used to determine linear contrail coverage over the Northern Hemisphere during 2006. Commercial aircraft flight data are employed to filter false contrail detections by th...
Article
Full-text available
Understanding the role of contrails in the Earth's radiation budget requires an accurate characterization of their macrophysical and microphysical properties, such as cloud top temperature, optical depth, and effective particle size. These properties are derived from 2006 MODerate-resolution Imaging Spectroradiometer data over the Northern Hemisphe...
Article
This paper describes a hybrid approach, using bibliometrics and text-mining, used to analyze longitudinal trends in the literature of e-marketing research from 2001 to 2010. The abstracts of 888 articles from six leading marketing journals were analyzed. The analysis identifies several core topics and themes of e-marketing research and reveals tren...

Conference Paper
Gaining an understanding of cirrus cloud impact on the climate system and the processes that influence their micro and macro-scale properties is essential to understanding climate and general circulation. Satellite observations can provide a wealth of information about cirrus clouds, but it is vital to validate the remotely-sensed parameters and to...
Conference Paper
The rise of mobile computing provides a novel medium for the dissemination of satellite imagery and cloud products to end users. The authors describe an application built to explore the delivery of satellite-derived cloud products to mobile devices for research purposes and other applications. This project builds upon earlier work performed at NASA...
Conference Paper
One of the great challenges for many Near Real-Time (NRT) geophysical applications is accessing data and services in a efficient and timely manner across heterogeneous and distributed systems. Applications that rely on NRT input data are at the mercy of the provider to make the data available as soon as possible and make them accessible in a common...
Article
Real-time satellite derived clouds products are gaining acceptance in model assimilation and now-casting applications. At NASA Langley, we are producing and archiving real-time products from geostationary and polar orbiting satellites. The products from full-disk geostationary satellites, GOES-11, GOES-13, Meteosat-9, MTSAT-2R, FY2E are merged toge...
Conference Paper
Full-text available
An automated contrail detection algorithm (CDA) is developed to exploit six of the infrared channels on the 1-km MODerate-resolution Imaging Spectroradiometer (MODIS) on the Terra and Aqua satellites. The CDA is refined and balanced using visual error analysis. It is applied to MODIS data taken by Terra and Aqua over the United States during 2006 a...

Article
Weather prediction models need more quantitative weather information for forecasting and nowcasting. This paper describes a prototype system to provide 3-hourly cloud properties from full-disk geostationary satellites (GEOSat) around the globe. Data from GOES11/12, Meteosat.-9, FY2-C/D and MTSAT is analyzed using a common set of algorithms to deriv...

A near-real time analysis system has been developed to retrieve cloud and radiation properties from operational geostationary satellite imager data. It is currently being applied to GOES-11/12, Meteosat-9, and MTSAT-1R, as well as to polar orbiting satellite imagers. The North American domain, which includes much of Canada, the USA, and Mexico, is...

A set of cloud retrieval algorithms developed for CERES and applied to MODIS data have been adapted to analyze other satellite imager data in near-real time. The cloud products, including single-layer cloud amount, top and base height, optical depth, phase, effective particle size, and liquid and ice water paths, are being retrieved from GOES-10/11...
