WSR-88D Common Operations and Development
Environment (CODE)
• An algorithm development environment for the WSR-88D
• Contains software and guidance to create the development
environment on an Intel PC running Linux Red Hat
Enterprise Workstation 4 (also, Enterprise 3 for Public CODE)
– Provides a 'clone' of a WSR-88D Radar Product Generator on a
workstation which can run existing and user-created algorithms by
ingesting WSR-88D Level 2 data
– Also used to study past weather events by ingesting Level 2 data
obtained from NCDC and creating products for analysis
• Includes visualization tools, data sets, documentation, and
•
•
•
•
the operational RPG baseline source code
Developed and maintained by the NWS OS&T
Updated with each new WSR-88D RPG software release
Used by groups that implement software for future RPG
releases, technique developers, and researchers
A Public Edition is available at http://weather.gov/code88d/

Summary
• Priorities determined with field input
–
–
–
–
1. Dual Polarization
2. Super Resolution
3. SPG products using TDWR data
4. Whatever else can be done with remaining resources
• OSIP ensures conops, requirements and business case
•
•
•
•
•
developed to support implementation
Resource profiles limit quantity of change
AWIPS & NEXRAD SRECs determine release content
Longer time between major releases lengthens time to
deployment and complicates integration
Prototype, test, and demo platforms representative of the
intended operational environment can foster design
refinement and reduce the risk of deploying defects
User input and feedback is critical

NWS Weather Radar Science Evolution Vision
• Continuing investment in the scientific utilization of
weather radar data is critical to the fullest realization of
the potential operational benefits of investments in
hardware and systems.
• Improvements in scientific uses of weather radar data
can be expected indefinitely, as each innovation
triggers ideas for new approaches, and as synergisms
in the use of radar data with other environmental data
are explored.
2nd Workshop on NWS Severe Weather Warning Technology (July 2007): The Future of NEXRAD
Slide 22
NWS Weather Radar Science Evolution Concept
• Programmatic/Budget Structure
– NEXRAD is not equivalent to ‘just the WSR-88D’
– NEXRAD is a Program covering O&M of installed capabilities, and
–
–
–
–
–
–
acquisition of significant new capabilities
The initial WSR-88D acquisition was the first NEXRAD project
NEXRAD Product Improvement is a sub-set of NEXRAD with a focus
on acquisition of new technology and science
ORPG, ORDA and Dual Polarization are recent NPI WSR-88D projects
FAA Data Utilization is a current NPI non-WSR-88D project
Science Evolution is an on-going NPI project to improve the benefit of
installed weather radar technology for operational missions
Future, potential, radar technology acquisitions (e.g., PAR, CASA-like
X-band) would be managed under the NPI Program
– NEXRAD and NPI are well-known elements of the
DOC/NOAA/NWS budget submissions for both O&M and
acquisitions
