Dual‐polarization radar products for biological applications
Ecosphere, 2016 The upgrade of the national network of next‐generation weather surveillance radars (NEXRAD) in the United States to dual polarizations has been completed, providing three additional routine data products: total differential phase (ψDP), differential ...

Mining sensor datasets with spatiotemporal neighborhoods
Journal of Spatial Information Science, 2013 Many spatiotemporal data mining methods are dependent on how relationships between a spatiotemporal unit and its neighbors are defined. These relationships are often termed the neighborhood of a spatiotemporal object.

Eos, Transactions American Geophysical Union, 1990 Full‐scale production of the NEXRAD (Next Generation Weather Radar) system was authorized January 31 by Robert A. Mosbacher, Department of Commerce secretary. The 165 Doppler weather radar units will provide earlier warning of severe storms and increase the accuracy of weather forecasts.

Eos, Transactions American Geophysical Union, 1983 Two firms have been selected for negotiation for preproduction models of NEXRAD, the next generation weather radar system that aims to improve severe weather forecasting. The 40‐month, cost‐plus‐fixed‐fee contracts, each valued at $20 million, were awarded to Raytheon Co. of Wyland, Mass., and to Sperry Corp.
