| Zusammenfassung |
| A better understanding of the interactions between ice and snow and the atmosphere requires
improved measurements of energy, mass and momentum fluxes, which continue to have a
high degree of uncertainty. In this communication, observed near surface fluxes of
momentum, heat and mass (H2O and CO2) over a boreal lake during a freezing period
(winter 2015/2016) will be analysed and compared with observations over ice free
lakes.
Continuously measurements of near surface fluxes of momentum, heat and mass (H2O
and CO2) are obtained with a new eddy covariance (EC) system, the Campbell Scientific’s
IRGASON Integrated Open-Path CO2/H2O Gas Analyzer and 3D Sonic Anemometer, over
lake Vanajavesi in Finland. The measurement site is located in a tip of narrow peninsula on
the lake (61.133935˚ N ; 24.259119˚ E), offering very good conditions for eddy
covariance flux measurements. The EC system was installed at 2.5m height above
the lake surface and was oriented against the prevailing wind direction in the site. |
