Doppler Winds Experiment
Principle Investigators :
John Gamache (HRD)
Team Members :
Joe Griffin (HRD)
Nancy Griffin (HRD)
Peter Dodge (HRD)
Frank Marks (HRD)
Collaborators :
David Parrish (NOAA/NCEP/EMC)
Jim Purser (NOAA/NCEP/EMC)
Contacts :
Colin McAdie (NOAA/NCEP/TPC)
Alan Goldstein (NOAA/AOC)
Objectives :
To analyze airborne Doppler radar observations for the following
purposes:
- To send a hurricane wind field to TPC in real time from the P-3s
- To send intelligent local averages (a.k.a. superobs) of Doppler
radial velocities to NCEP/EMC in real time from either the P-3 or
the Gulfstream-IV aircraft
Milestones:
- Feb. 1, 2003 - Modify/develop software to read data in present
AOC format into Gamache interpolation software
- Feb. 1, 2004 - Modify/develop software to compress HRD wind
analyses for sending over satellite data stream
- Feb. 1, 2004 - Develop software to remove noise, data with
unacceptable spectral width, and reflectivity of the ocean surface,
from the radar data stream. Agree with EMC about structure/nature
of prototype superobs to be sent for assimilation of data
- Mar. 2004 - Present results at the Interdepartmental Hurricane
Conference
- Apr. 1, 2004 - Develop and/or modify, and then incorporate,
an automatic dealiasing scheme
- May 15, 2004 - First year annual report and renewal proposal
- Jun. 1, 2004 - Test automatic data-cleanup/interpolation/synthesis
software using cases already cleaned up and analyzed by human analysts
and compare with their research wind fields. Concurrently test-run
software on the workstation that will operate on P-3 aircraft.
Develop software on airborne workstation that will construct superobs
from radar data stream. Develop communication software that will send
compressed analyses/superobs through the aircraft network/satellite
communication system
- Jul. 2004 - Install workstation aboard aircraft
- Aug.-Oct. 2004 - Produce real-time Doppler analyses automatically
aboard aircraft during 2004 Hurricane Season
