       The Horia Hulubei National Institute for 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.
      The 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.
      The meteorological tower has the highest measurement
    level at 60 m and the intermediate measurement level at 30 m.
      Due to restrictions in national regulation, the meteorological tower was
    build on IFIN property, nearby a forest
    and surrounded by buildings.
      The Tower was built beetween 1994 and 1996 with contribution from the Romanian
    Government and IAEA Vienna (providing meteorological sensors)
      The tower is located nearby building 33 on the IFIN-HH area.
      The minimum distance to forest border is 360 m (West direction) and the
    maximum is 1240 (East directions). The obstacle heights around the
    meteorological tower are about 12-15 m. This is a situation of non-uniform
    roughness and the wind profile is strongly disturbed.
      The classic approaches in the literature do not allow
    a robust assessment of the atmospheric stability in such conditions.
    Consequently, the research on nuclear meteorology must be
    achieved for urban and sub-urban areas.
      The meteorological tower was worked with 2-3 levels of
    measurements in 1998-2000, with 7200 hours of good performance
      During the time when the met tower worked on-line in real
    time, it provided useful information for decision support system in
    case of nuclear emergency (The EU RODOS project).
      After a period of financial constraints, the tower was refurbished in 2007 and
    restarted its operation at the end of 2008.
      Using the resources provided by an international project, RADO
    (Romanian Atmospheric 3D Observatory), financed by the Innovation
    Norway, different upgrades were done (ceilometer, net radiation
    sensor, sonic anemometer, infrared gas analyzer, radon monitor).
      Afterwards, National Agency for Scientific Research provided
    the financial resources for the next on going upgrades (the present weather
    sensor, high precision and robust sensors for temperature, humidity
    and wind, as well as fast sensors for eddy covariance).
      Finally, the system must assure all the surface
    information needed in nuclear safety.
