• CRAFT
• Applications
• NWS distribution
• UPC involvement
• Next Steps

Roots

• 1998 discussions with reps from USWRP, OU,
  Unidata, NCAR, FSL, et al
• Use of LDM to distribute Level II data for
  universities and to NCDC for archival
• Unanimous endorsement for UPC to proceed with
  collaboration at 1998 Policy Committee meeting in
  R.I.

3
Roots-cont.

• Collaborative Radar Acquisition Field Test
  (CRAFT) was born
• Main goal ..to demonstrate real-time
  compression and data distribution of multiple
  radars delivering Level II data with a view
  toward nationwide implementation technology
  transfer!

Why Level II Data?

• Level III (NIDS-type) are digital products
  (pictures)
• Level II provides full resolution digital data
  all elevation angles full data precision
• Level I is too voluminous-includes IQ in time
  series from reflectivity, velocity, spectrum
  width (nuts and bolts of data)
• Level II is research quality data

5
CRAFT

• Successful collaboration with stakeholders from
  universities, private sector, government
• Testing and refinements with LDM and NSSLs
  compression (Bzip2) with initial 6 radars
• Use of LDM to move data from radars to NCDC for
  archiving requirement
• Allowed transition from 8mm Exabyte tapes
• Huge cost savings and reliability realized

6
CRAFT-cont

• Currently 102 radars
• 35 sites receiving data from OU-CAPS
• 17 universities
• 12 government
• 6 private industry
• 1 March- NWS will have 121 NWS and 3 DOD sites on
  CRAFT/NWS Network
• NWS will announce options for distributing Level
  II data by end of Feb 2004

7
Applications

• Use in courses to expose students to full suite
  of radar information-future plans include
  mesoscale modeling
• Cloud and wind analysis mesoscale data
  assimilation
• Initializing forecasts
• Support NASAs Tropical Rainfall measuring
  Mission (TRMM) Ground Validation Program
• Real time storm tracking
• Spotter operations
• Experimental correction of echo tops research
• Storm-scale data assimilation and numerical
  prediction
• Visualization with IDV and IRAS
• Storm analysis and radar data quality
  improvements
• Creating special products for customers
• Data archival

8
NWS Distribution

• ROC/NWS active CRAFT stakeholders
• CRAFT deemed an appropriate project for
  technology transfer to NWS operations
• NOAA/NWS became Abilene collaborator
• Use of Internet2 High Speed Network to support
  distribution of Level II data to NCEP, NCDC, and
  academic community
• Private sector has 10 sec latency requirement
• NCEP has 60 sec latency requirement
• NWS held meeting in June, 2003, to discuss
  proposed method of data distribution using
  Internet
• Private sector responded by recommending FOS
  option

• Family of Services Proposed Radar Products
  Service II Estimated Costs
• One Time Cost (OTC) for processors (servers),
  routers, router I/O cards,
  cables, matrix switch I/O cards, etc. (68K)
• OTC will be spread out over a period of 5 years
  to minimize the cost to external users (13.6K)
• Other Direct Cost (Includes OTC) (15K)
• Direct Labor Cost (42K)
• Distributed (Indirect) Costs (25K)
• Total Product/Service Cost (83K/YR)
• Estimated Quantity (4), (5), (6), (7), (8)
• Final Product/Service Price (21K), (17K),
  (14K), (12K), (10K)

10
NWS Distribution Status

• Solicitation sent 12/05
• Evaluations conducted by
• 3 Unidata technical staff
• 3 NWS technical staff
• Point system to each proposal-Miller collected
  all evaluations and tallied outcome sent to NWS
• Awards will be announced after MOAs have been
  signed by selectees

11
NWS Distribution UPC Involvement

• UPC involvement
• LDM 6
• Coordination with NWS Hdqtrs for a Call for
  Participation for top level sites to provide
  Level II data distribution to universities,
  government, private industry
• Terms of Call freely available to univ, gov,
  and on cost recovery basis for private industry
• Sign an MOA with NOAA/NWS with terms associated
  with the solicitation.
• Solicitation-not FAR (Federal Acquisition
  Regulation)
• UPC to provide LDM training to NWS regional
  hdqtrs staff

12
NWS

• 4 sites will provide LDM data distribution of
  Level II data
• 2 sites were pre-selected by the NWS
• Mid-Atlantic Crossroads (Max) GigaPop (collocated
  with Univ of Maryland)
• ERC GigaPop (collocated with NCDC-Asheville)
• 2 remaining sites to be selected

Next Steps

• Unidata to train regional hdqtr sites
• Salaries, benefits, travel covered by NWS
• Assist selected top level sites with IDD
  topology, if desired
• Provide support to top level lt.edugt sites
• Provide support for lt.edugt recipients of data
