  7. Mean TemperatureSoutheast USA 1899-2003 Models Observation

  8. For high resolution monitoring of Precipitation: 2000+ spatial Degrees of Freedom?

  9. IDEAL: 1500 in AL? Station siting for applications on radar/satellite calibration, temperature distribution (i.e. chill hours, Tmin etc.), drought monitoring, soil moisture calibration, etc.

  10. COOP-modernization Goal initially was to put a station in every 20x20 mile grid box = ~150 stations in AL. New goal is to replace HCN stations (about 1200 US, 15 AL) around the country

  11. Establishing CRN Stations • NCDC performs Site survey/site selection, installation etc. • About $50K per station • 3 stations funded over 2 years • Auburn Agricultural Experiment Stations best siting solution • 1 NE Highlands, 1 Blackbelt plains, 1 near coast

  12. USCRN CONUS Deployments Installed Pair (14) Installed Single (59) Partner sites (3 in AL) + 4 in Alaska and 2 in Hawaii

  15. ALABAMA HCN

  16. ALABAMA HCN/COOP-M

  17. ALABAMA COOP TO HCN

  18. Establishing COOP-M, HCN Stations • Funding from congressional appropriation FY05: 2 CRN, 7 CRN-Lite • Desire for stations that meet federal standards for operations and climate • COOP-M Site selection committee NWS/HQ, NWS/SR, NWS/WFO, NCDC, SC, others • Selected equipment utilized by CRN network, dubbing the stations as “CRN-Lite” - Geonor gauge and triple-platinum resistor thermisters, NIST calibrated, double aspirated. Wind at some sites.

  19. Establishing COOP-M, HCN Stations • Site survey/site selection are 99% of the effort • AL situation: NWS personnel performed surveys (about 10 per WFO) • Repeat surveys are the norm • USHCN stations are priority for COOP-M • What about the COOP station number? Should be different from old HCN for overlap studies and archiving of simultaneous data

  20. Establishing COOP-M, HCN Stations • FY06 appropriation for 1 additional CRN ~45K (Gulf-Coast) and 7 COOP-M (~$25K each) • 11 COOP-M and 3 CRN now operating • 2 sites approved, 5 more to finish the 15 HCN stations • 4 new COOP-M commissioned as HCN and 2 new CRN expand original HCN network in Alabama from 15 to 21

  21. Valley Head HCN Backyard Station

  22. New Historical Climatology Network Station for Regional-Level Climate Monitoring(Valleyhead, Northern Alabama) High-risk reduction precipitation gauge in small wind shield Satellite Communications Wetness sensor One ventilated radiation shield containing three high-precision temperature sensors Data logger & power control Selected other instruments are added to this climate monitoring station as needed

  30. Future Plans • If money request comes through: • Add 5 more stations, 2 in TN • Expand current stations with humidity, soil moisture, wind • Begin data analysis and overlap comparisons for homogenization effort
