Objectives (5 yr plan)

• 3.2.1 To take measurements of CO 2 fluxes and energy balance above the main vegetation types in the region during the five year period and during the intensive observation period.
• 3.2.2 To perform regular measurements of the fluxes of heat, water vapour, CO 2 and momentum with a low flying research aircraft (Sky Arrow).
• 3.2.3 To measure the city emissions of Bordeaux and Toulouse at selected periods.

Outline of work plan

Task 3.2.1Continuous tower-based measurements. Measurements are taken along the most dominant land cover types in the experimental domain (see detailed 18 month plan) by INRA and CNRM and Alterra additional during the intensive period.

Task 3.2.2 During the test campaign IBIMET and ISAFOM will fly their Sky arrow in the domain to test the feasibility and produce test data for modelling development as well as producing high resolution visible RS images of the area around tower location and selected transects.

Task 3.2.3 During the intensive campaigns Alterra will bring in an additional Sky Arrow for flux measurements.
