Real-Time Data (RTD) Chronology of Events Informal efforts conducted since 2003 demonstrating transmission and display of lower fuselage radar data and the 1 Hz serial data stream (flight level, SFMR, etc.) Real-Time Data (RTD) working group established in November 2008 Goals: To define and execute the formal pathways/procedures to flow data from the NOAA aircraft into NCO for operational utilization by NWS Key members: Michelle Mainelli (NCO), Jim Carswell (RSS), Sean McMillan and John Hill (AOC), Paul Chang (NESDIS) and Dan Starosta (TOC) HFIP Observation Team established in November 2008 with one of its goals to: Transmit new data types from P3s (Doppler, AXBT, AWRAP, 1-Hz flight-level, WSRA), including software development. $60K of HFIP funding became available in 3Q FY09 to help support some of the software development work.
Project Objectives Question: Can we help? If so how? • Real-time Radar / Data Server: • Aircraft-ground data communication server will provide in near real-time: • Processed Tail Doppler Radar Profiles (Doppler, spectral width, Z) • Lower Fuselage Reflectivity Profiles • Scientific Data • File Builder will provide: • Radar meta data files to NCO as the data becomes available. Will contain processed Tail Doppler and/or Lower Fuselage radar profiles. • Scientific and AXBT meta data files. • Quality of service will be implemented that monitors aircraft-ground communications and automatically handles disruptions. • Demonstrate capabilities in Winter Storms 2010.

Project Goals Purpose: Can we help? If so how? • Data Availability: • Provide Tail Doppler Radar profiles, Lower Fuselage Radar profiles and scientific data through same system. • Send data via packets and/or file based. • Extend real-time access of all data to NHC, HRD, STAR and other potential users. • Ground Processing: • Enable ground processing of data versus processing data on board aircraft (e.g. John Gamache’s Doppler processing) by transmitting “raw” profiles. • Data Visualization • Integrate radar data into the RSS Real-time Data Display as mosaic background imagery.

Real-time Radar Profile Data • Airborne Server: • Receives data packets from Sigmet processor & extracts radar profiles. • Archives radar profile and ancillary data. • For lower bandwidth data links, further profile data processing implemented (i.e. range gate averaging, bit remapping, compression, Gamache’s Doppler processing) to reduce data rates to within link budget. • Build compressed packetized data and transmits to ground server. • Transmits data as soon as it becomes available. • Ground Server • Receive packetized data, and rebuild radar profile data. • Implement quality of control and ground processing of radar profiles. • Build NCO standardized radar files and send to TOC server as they become available. • Relay data packets to subscribed users.
