  4. A definition for ”testbed” (Dabberdt et al. 2004): ”A testbed is a working relationship in a quasi-operational framework among measurement specialists, forecasters, researchers, private-sector, and government agencies aimed at solving operational and practical regional [insert phenomenon or forecast challenge] problems with a strong connection to the end-users. Outcomes from a testbed are more effective observing systems, better use of data in forecasts, improved services, products, and economic/public safety benefits. Testbeds accelerate the translation of R&D findings into better operations, services, and decision-making. A successful testbed requires physical assets as well as long-term commitments and partnerships.”

  5. Research plan • Water phase: rain/snow/mixed • Visibility • Fog and precipitation phase and intensity • Inversion height and strength • Air quality model • Sea breeze • Sensitivity tests with local area models • Road surface radiation balance model

  6. Snowing on Nov 20th 2004, Helsinki Measurement periods and themes: • (May 2005 test of communications) • August 2005 • Nowcasting by extrapolation • World Championships in Athletics • No database yet, limited remote sensing instrumentation • November 2005 • Snow/rain • January-February 2006 • Stable boundary layer and inversions • May 2006 • Sea breeze, fog • August 2006 • Convection Convection on Jul 5th 2003, Helsinki

  7. For clarity, Finnish Road Administration’s road weather stations are mapped separately All stations except road weather stations (plan on 21.1.2005):

  8. Estimate for intense area: • 16 (FMI), • Vaisala, • Kumpula, • 30 link masts, • 20 other WXTs and standalone loggers, • 3 ship, • 9 precip stations, and • 23 road stations. • 103 pcs. • Avg station distance of 8,7 km Compare to 138 automated FMI stations in whole country  Avg station distance of 49,5 km FMI’s automatic sites for Helsinki testbed & comparison: ~170 km Intense network with most WXTs Larger area incl. model fields ~90 km

  9. Suggested Unibase masts, 60-100m height; (plan on 19.1.2005): Heights: 2m and mast top Masts with 3 heights, middle height doubled

  10. Ceilo (triangle: CT25K, circle CL31) Sounding (circle) and possible profiler sites (triangle)

  11. Rain measurements -belt: radar 20-60km -dot: manual obs -big diamond: FD12P -small diamond: potential FD12P -triangle: autom snow depth -square: weighing gauge

  12. FMI automated surface station (circle) and manual activity (big circle)

  13. Surface WXT510 & standalone loggers; mainly Helsinki area: Helsinki Hernesaari testbed Helsinki Bulevardi testbed Helsinki ydinkeskusta testbed Helsinki Eläintarha testbed Helsinki Vallila testbed Vantaa Tikkurila testbed Helsinki Olympiastadion testbed Helsinki Roihupelto testbed Espoo Leppävaara testbed Nummi-Pusula, Loukku testbed Helsinki Itä-Pakila heat island Vantaa Pakkala heat island Vantaa Asola heat island Helsinki Tapulikaupunki heat island Sipoo, Östersundom heat island Kirkkonummi Sundsberg heat island Vantaa Riipilä mäki heat island Vantaa Riipilä laakso heat island Helsinki Harju heat island Helsinki Pitäjänmäki heat island Helsinki Itä-Pakila heat island ------------------------------------------------------------------------ Total 21 pcs.

  14. Remote sensing: • 3D composite of FMI 4 Doppler C-band radars • Estonian radar in Tallinn • C-band dual polarimetric radar • Lightning location • RASS + mobile wind profiler • Meteosat 8 Seviri • NOAA • Ceilometers CT25K & CL31

  15. Other considered data sources: • Soundings (Jokioinen, Uusimaa, Tallinn) • GTS transmitted surface and remote sensing observations • Other masts (Kivenlahti, Loviisa, Kumpula etc.) • Air quality data (Helsinki metropolitan area council YTV) • Newspaper weather maps • Hirlam forecast fields • SatReps • SAFs
