| Urban Boundary-layer Atmosphere Network | . |
The Network
Helsinki is the capital city of Finland (northern Europe). For a summary, see our overview poster. Here is a brief list of our observations of Helsinki's boundary-layer atmosphere:
- Eddy-covariance stations (fluxes of momentum, sensible heat, latent heat, gases and particulates) - e.g. SMEAR-III
- Scanning doppler lidar (HALO Photonics Streamline)
- Vertically-pointing sodar (LATAN-3 1D)
- Dual-beam scintillometers (Scintec BLS-900)
- Short-path laser scintillometer (Scintec SLS-40A)
- Thermal imaging camera
- Vaisala ceilometers
- Metek SODAR with RASS extension
Related model developments
Beyond the core observational network, modelling will help to understand Helsinki's ABL. Further, we expect that some models might be improved as a result of analysis of data from Helsinki UrBAN. Examples of relevant models at FMI and UoH:
- SUEWS (Leena Järvi)
- HARMONIE, AROME, SURFEX (Carl Fortelius, Sylvain Joffre)
- LES (Antti Hellsten)
- MPP (Ari Karppinen)
- Pedestrian slippery index model (Markku Kangas)
- Urban air-quality forecast system, UAQFS (Mari Kauhaniemi)
Collaborations and data sharing:
In principle, we would be happy to jointly work with other researchers or end-users.
We do not currently have a formal data policy.
Please contact Curtis Wood or Leena Järvi (and we can discuss via email, and/or forward your email to other relevant people), if you would like to:
(i) use our data, (ii) collaborate, (iii) bring yourself to Helsinki, or (iv) bring your equipment to Helsinki.
For observations:
- Data archive table and plots
- Other relevant projects include, e.g. Helsinki TestBed or Air Quality in Finland.
Some sites and equipment:
This work has been supported by many funding sources:
(i) direct funding from Finnish Meteorological Institute; (ii) the EC FP7 ERC Grant No. 227915 "Atmospheric planetary boundary layers physics, modelling and role in Earth system"; (iii) Finnish Acadamy grants; and (iv) other sources.
