Figure 6: Daily means of (a) 2-m air (Ta ) and near-surface water temperatures (Tw ), (b) vapor pressure deficit (VPD), and (c) wind speeds (WS ) collected at the raft and shore sites. The period with ice cover (shaded area) was determined from time-lapse photos.
The distribution of the wind direction measured from the raft flux tower followed a bimodal pattern, aligned along the SSW-NNE axis of the reservoir. Wind measured from the reservoir at the shore flux tower showed the same pattern. The 30-min mean wind speed was 5.6 m s−1 while the maximum wind speed reached 19.4 m s−1.
