After more than 25 years of operating meteorological satellites, the United States now maintains a ground data handling and distribution system that has incorporated many technologies developed during the period. Because this system represents a considerable investment, future upgrading and replacements must not only be carefully planned, but ...

Public Understanding of Science, 2009
Complex scientific visualizations are becoming standard parts of many educational experiences, both in and out of schools. We found that satellite visualizations used by ocean scientists were difficult for teachers, students, and museum visitors to understand.

Selected Issues Papers
Cambodia is not alone in facing capacity limitations in the production and timely release of key official statistics needed for data-driven policy decisions. This paper demonstrates that combining satellite-derived indicators (e.g., nighttime lights, NO₂ emissions, vegetation indices) with traditional high-frequency indicators in a machine learning ...

Data distribution by satellite
Journal of the Institution of Electronic and Radio Engineers, 1988The current environment of satellite communications and the opportunities for new satellite based services are described. Data distribution is one such service which can be offered on a flexible basis with call-by-call and demand assignment. The paper outlines the main features of a data distribution system known as Pandata, which combines the use of ...

Nature, 1961
USING the method outlined in previous papers1–3, I have completed an analysis of an extensive series of observations on satellite 1958 δ2 (ref. 4), and propose to outline an interesting implication of this work prior to the publication of the detailed analysis.

SEARCH FOR CLIMATE TRENDS IN SATELLITE DATA
Advances in Adaptive Data Analysis, 2009Unambiguous determination of trends is the central theme of climate change studies. A promising way to validate and quantify a warming trend of few degrees on a time scale of a century, predicted by climate models, is the use of measurements provided by satellites. However, climate variables, such as temperature and concentration of water vapor in the

Satellite data assimilation for societal benefits
2016 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2016Satellite data assimilation for societal benefits is demonstrated using high quality ATMS and CrIS radiance data for improving forecast skill of landfalling hurricanes and typhoons. A comprehensive SDR (CSDR) from ATMS, CrIS and VIIRS is created and allows for maximizing the benefits to numerical weather prediction data assimilation.

Multibeam antennas for data communications satellites
Proceedings of the fifth symposium on Data communications - SIGCOMM '77, 1977This paper presents a survey of the state-of-the-art in multibeam antennas, as particularly applicable to data communications satellites, and analyzes a new configuration to meet such specific needs over the U.S. during the 1980's. Three basic forms of multibeam antennas are described—those providing space diversity, polarization diversity and variable-

Abstract : In this paper we provide a survey of the history, technology and economics of commercial satellite data communications. Technological and economic trends in satellite data communications are examined, and the differences between the satellite channel and terrestrial channels are emphasized.
