Project CRAFT: A Real-Time Delivery System for NEXRAD Level II Data Via the Internet

Abstract

A multi-institution collaboration demonstrated real time compression and Internet-based transmission technology to make possible an affordable nationwide operational capture, distribution, and archiving of Level II WSR-88D data.

Convective-Scale Warn-on-Forecast System

“…The advent of the national network of Doppler radars [Weather Surveillance Radar-1988 Dopplers (WSR-88Ds); Crum and Alberty 1993;Crum et al 1998] in the early 1990s and the more recent ability to transmit, composite, and merge all the radar data in near-real time (Kelleher et al 2007;Langston et al 2007) allow for the assimilation of in-storm Doppler radar reflectivity and radial velocity observations into convective-scale forecast models. Snyder and Zhang (2003) demonstrate that synthetic Doppler radar observations from a simulated thunderstorm can be inserted successfully into a convective-scale numerical model using an ensemble Kalman filter data assimilation method.…”

CloudCast: Cloud computing for short-term mobile weather forecasts

“…To perform measurements in a large-scale setting we replicate a distribution system that, at least on the network level, is similar to the NEXRAD system. Kelleher [25] et al give an overview on how data from the NEXRADs is disseminated by using NOAA's NOAANet backbone and Internet2. Since we do not have access to NEXRAD nodes for our measurement, we make use of PlanetLab [17] a global research network that supports large-scale, distributed experiments.…”

Estimating animal densities in the aerosphere using weather radar: To Z or not to Z?

“…Often several weather radar stations are networked together to further extend the spatial coverage. For example, the US National Weather Service operates over 150 weather surveillance Doppler radars (WSR-88D) with the majority of these located in the continental US (Crum et al 1998, Serafin and Wilson 2000, Kelleher et al 2007. Collectively the network of radars is known as NEXt generation RADar (NEXRAD) and data from this network are freely available from the National Climate Data Center (NCDC) via the Internet.…”
