A Campbell Scientific Tripod Weather Station was installed at CERA in late May/early
June 2001. Use these links to view the
HOURLY DATA,
and DAILY DATA

bottom of these files. The weather station is equipped with sensors to measure the following
hourly and daily variables.
- Precipitation - Total (mm)
- Air Temperature - Average (°C)
- Relative Humidity - Maximum (%)
- Solar Radiation - Average (kWatts)
- Wind Speed - Average (meters/sec)
- Wind Speed - Maximum (meters/sec)
- Wind Speed - Direction (degrees)
- Wind Speed - Standard Deviation (degrees)
- Precipitation - Total (mm)
- Air Temperature - Max (°C)
- Air Temperature - Hour and Minute of Max
- Air Temperature - Min (°C)
- Air Temperature - Hour and Minute of Min
- Relative Humidity - Maximum (%)
- Relative Humidity - Hour and Minute of Max

- Wind Speed - Hour and Minute of Min
- Wind Speed - Direction (degrees)
- Wind Speed - Standard Deviation (degrees)
Sensors to measure soil temperature and soil moisture have been installed in each of four plots receiving a different treatment in teh fire/mow experiment. Due to faulty temperature and moisture sensors, we have sporadic data between June 2001 and early September 2002. We have a complete data set for all four plots for both variables starting September 7, 2002.
