Searching...Vaira: 2007-01-10 10:20:00 (DOY 10)
Author: Siyan Ma
Others: Dennis, Youngryel, Becca,
Phenology: more grass germinated in Vaira, haven’t grown very much since last visit. Grasses under the trees were greener and
bigger than those in the open area.
During the nighttime, more long-wave radiations were reflected by tree
canopies back to the ground. Minimum temperature was higher under the tree than
in the open area.
Summary
- Power on Floor site is OK.
No data lost. Hoarry!!!
- Soil CO2 profile
worked well.
- Check and download data at
Tower and Varia.
EC systems worked well.
- Ta&Rh sensor was hung out of shield, no
aspirator, no protection from radiation!!! Dennis fixed it. Old data will
have bias.
- DDB cleaned Pyranometer, NDVI surfaces –
looks like dead decomposing spider on ~10% of surface.
- dendrometer, soil moisture, and spectrume were measured. Dendrometers
need reset because some have been out of range!!!
Vaira_Grass Site
- Fence and gate power: >12 v.
- Panel and Batteries: 13.3 v; 8.7
amps; 2.7 amps.
- Reading from Gillsonic screen before downloading data. (The value of H2O and CO2
should be in the range of 0 – 5 v.)

- downloading data OK
- check
the fans of air temp. and relative humidity
sensors at Vaira. Ta&Rh sensor was hung out of shield, no
aspirator, no protection from radiation!!! Dennis fixed it. Old data will have bias.
- DDB cleaned Pyranometer, NDVI surfaces –
looks like dead decomposing spider on ~10% of surface.
- Check MD-9 system connections
OK
- Closed gate and set up fence.
Went back and turn it on.
- Youngryel
took spectrum measurement on the normal points and under the tree. Grasses looked greener and bigger under
the tree.
