VUcontribution to CERES

1
VU-contribution to CERES

• R.J. Ronda, L.F. Tolk and A.J. Dolman

2
VU operations in Marmande

• RASS/SODAR profiling system for wind speed and
  temperature (continuously operated since Friday
  13th May 2005)
• Scintillometer for measuring the sensible heat
  flux along a 150 m path over the Maize field

3
Determining the wind speed profile

Plans

• Comparison of wind speed and direction and
  temperature profiles with profiles Sky Arrow
  IBIMET and Piper Aztec
• Comparison SH fluxes with eddy-correlation
  measurements of Alterra Sky arrow IBIMET fluxes
• Use of RASS data and nighttime CO2 buildup
  testing the virtual tower concept
• Use of all the data in (inverse) modeling studies
