What is Helsinki Testbed ?
  • Helsinki Testbed project goals broadly consist of mesoscale weather research, forecast and dispersion models development and verification, demonstration of integration of modern technologies with complete weather observation systems, end-user product development and demonstration and data distribution for public and research community.
  • The initial project (01/2005-08/2007) was first designed to be periodic research project of mesoscale meteorology. Real time data was planned to be publicly available and measurements were to be done during specific measurement campaigns. On the course of the project additional periods of March-April, June-July, September-December 2006, and January-August 2007 were decided to be available as well on the web.
  • Starting from September 2007 Testbed continues to serve as research and development platform for UbiCasting and other projects. For the extension period Finnish Meteorological Institute and Vaisala have run the network infrastructure called Helsinki Testbed Baseline Network. At the same time the web service has continued, and serves public at least until October 2009. Note that this network has experimental status.
  • Many Finnish industry and research institutes have participated Helsinki Testbed. Along with the Ubicasting project several new partners have joined in the core Testbed interest group, such as University of Helsinki and Insta DefSec. The main financier of the project continues to be Finnish Funding Agency for Technology and Innovation (Tekes).
