This website plots data from three urban micrometeorological sites of SMEAR III station in Helsinki:
Kumpula (60 12' 10.14''N 24 57' 40.06''E). Measurement period 1 Dec 2005 onward.
Hotel Torni 1 (60 10' 04.09''N 24 56' 18.69''E). Measurement period 28 Sep 2010 onward.
Hotel Torni 2 (60 10' 04.05''N 24 56' 19.07''E). Measurement period 26 Jun 2013 onward.

The figures are updated every night.



Data from the past 28 days.

The time ticks are days of month. Some of the flux data is omitted due to flow distortion. These wind directions are: Kumpula 0<WD<50, HotelTorni1 50<WD<185, HotelTorni2 230<WD<365

Spectra from the past 28 days

Data is shown only from times when the flux qualtiy is good and the wind direction is acceptable. Both unstable and stable cases are included and the absolute value has been taken of the co-spectra!
