The Tiksi Hydrometeorological Observatory Program International Collaboration for Climate Studies

1. The Tiksi Hydrometeorological Observatory ProgramInternational Collaboration for Climate Studies U.S. Science Contact: Taneil.Uttal@noaa.gov Russian Science Contact: Maksh@aari.nw.ru

2. The Supporting U.S. Russian Agreements and Memorandums

4. Tiksi in the context of the the International Polar Year

5. The Science ConceptCoordination of Arctic Observatory Measurements NOT JUST WEATHER STATIONS

6. Rational for Intensive Atmospheric Observatories • Weather stations only tell you HOW the climate is changing (but the long-term measurements are often not of sufficient stability to monitor long-term climate change) • Also need to know WHY the climate is changing. This requires more rigorous control on fundamental measurements (temperature, winds, pressure, precipitation) and ALSO supporting research grade measurements that will understanding the processes that control climate change. • ALSO Need to respond to the NOW issues • Sudden events

9. Existing Components • NSF/Polar Foundation infrastructure NOAA project coordination and long-term design • Government of Sakha road and power improvements • Roshydromet weather station upgrades – communications and weather station measurement systems • NOAA observation programs • Roshydromet observation programs • NASA observation programs • FMI observation programs

10. 2009 Program Activities • Logistics Team Meeting St. Petersburg in March ’09 - construction plan for finishing the site and Clean Air Facility improvements in August 2009 • Science Team Meeting in Boulder May ’09 - resulting in the finalization of a current science plan with 14 identified joint science projects • Training in US of Russian Technical Staff in July

13. Existing meteorological, measurements, as well as fast ice thickness, sea level, water temperature and salinity Place for fast ice, water temperature, and salinity measurements Place for meteorological observations Pavilion for radiosoundings Long term historical measurements make Tiksi a invaluable site

14. Weather Station built in 2006 Still requires plumbing and additional weatherization (in progress as of October 2, 2009)

15. Official opening of the New Tiksi Weather Station on November 28, 2006 President of the Republic of Sakha(Yakutia) Vyacheslav Shtyrov and Special Representative of the RF President on IPY issues Arthur Chilingarov

17. Clean Air Facility – Structure completed in 2008 Still needs conditioned power, additional electrical, Etc.

18. Special Requirements to be a Clean Air Facility

20. NOAA (intended) Contributions to Tiksi 2009 Baseline Surface Radiation Network Facility Flux Tower Climate Reference Network Site Ozone Flask Sampling Black Carbon Roshydromet Contributions to Tiksi 2009 Satellite Communications System for Data Transmission Flask Sampling Program Standard Russian Radiation Measurements Permafrost measurements UVB measurements Finnish Meteorological Institute to Tiksi 2009 Aerosol Sampling Green House Gas Sampling

21. Results of the 2009 Installation • Russian installations completed • Finnish installations partially completed • Some US sampling programs started • Most of the US equipment delayed in shipping and customs • Status of the Weather Station and the Clean Air facility reviewed

22. Radiation Sensors RUSSIAN INSTALLATIONS Instruments Aerosol Samplers

24. The wandering US shipment – still waiting word on deliver. Left Boulder on Aug 25 with a delivery estimate of 10 days To be continued……..
