Summary: Tower batteries need to be replaced because no nighttime data.

Feb. 22, 2011

It’s a beautiful sunny day. Grasses looked still weak. No tree leaf yet. See cows at Vaira.

Tonzi – Tower:
Everything worked well.
Downloaded data, but met data are only available during the daytime in many cloudy/rainy days. Thus, replace batteries is high considerable.
Power status: 13.4, 0.0, 2.5.
CO2 profile system still offline.

Tonzi – Floor:
Everything worked well.
Downloaded data.
Power status: 14.1, 14.3, 1.9.

Other data collection:
Soil moisture: input.
Groundwater: floor=20.4ft; tower=24.0ft; roadside=21.0ft. The sensor did not perform well.
Dendromenter: input.
Spectrum at Vaira: Since Young have proved that direct upward camera can capture better imagine to estimate tree leaf development, I think we should not use cosine filter on the spectralmeter either. The idea of cosine filter is similar to that of fisheye lens – correct various light directions to vertical light. However, the scope of the spectralmeter is much smaller than a digital camera.
