The Horia Hulubei National Institute of Research     and Development in Physics and Nuclear Engineering (IFIN-HH)     is one of the most important public R&D organizations in Romania.       IFIN-HH is about 3 km from Bucharest border and is situated in     the middle of a forest and surrounded by agricultural     land and peri-urban areas.       Exhaust radioactive products, of very low activity,     are emitted from stacks of 40 m height and the effective     source height is between 44 and 55 m.       We build the met tower with upper measurement     level of 60 m.       Due to restrictions in national regulation     the meteorological tower was build on IFIN property, in     the middle of forest and building area.       The Tower was building in 1994-1996 with contribution     from Romanian government and IAEA (providing meteorological     sensors)       The location of the tower is near building 33 in the IFIN area       The minimum distance to forest border is 360 m (West direction)     and the maximum is 1240 (East directions). Obstacle around have     a height of 12-15 m. This is a situation of non-uniform roughness     and the wind profile is strongly disturbed.       Classical receipts in the literature do not permit a robust     assessment of atmospheric stability in such conditions.       The meteorological tower was operated with 2-3 levels of     measurements in 1998-2000, with 7200 hours of good performance     only.       When operating in real time- on line, the meteorological tower     delivered useful information for application of decision support     system for nuclear emergency       After a period of financial constraint the tower was refurbished     in 2007 and restart operating in end 2008.       Using resources form an international project RADO     (Romanian Atmospheric 3D observatory), supported by Innovation     Norway- , some upgrades are on going (ceilometer, net radiation     sensor,sonic anemometer, infrared gas analyzer, radon monitor).
