BackgroundBackground

HCN-M Goals

• Enable continued monitoring and assessment of national and regional climate variability

• Sustain the historical climate record• Provide climate observational data, and station and

equipment metadata• Improve data quality• Distribute data to customers for current and future use • Provide a flexible and expandable architecture to integrate

with NOAA's Global Earth Observing Integrated Data Environment (GEO-IDE)

• Optimize as well as modernize the HCN

ChallengesChallenges

• Programmatic– NWS weather and water mission vs. climate

requirements– NWS policy and procedures for automated climate

systems are lacking – HCN-M system limitations e.g. lack of snow

measurements in initial baseline

• Administrative– The commissioning process is resource intensive– The time required for full system deployment will

likely exceed 10 years

ConclusionsConclusions

• An OT&E plan for the HCN-M has been prepared– The plan proposes a comprehensive system

evaluation that is fully integrated with HCN-M commissioning activities
