Australia's little recognized woodlands as soon as coated large components of the japanese part of our continent. Woodlands are uncommon from forests by means of the truth that their canopies don't contact, tree heights are typically reduce and so they frequently have a grassy understorey.

The results for ozone for the 30-35 m interval are displayed in Figure 5. The results for this height interval compare reasonably well with the results for this interval for heat. The uncertainty due to scatter however is much larger. For the other height intervals the scatter is even worse. For the interval 24-35 metre the comparison between heat and ozone is quite good.
When the leaves come out it will increase with about 5, which is the LAI efficient for CO,. The surface resistance to water vapour was calculated according to equations 2 and 3 after subtraction of the saturated water vapour concentration a t the surface temperature. The canopy stomata1 resistance was calculated by conversion of the resistance to water vapour to resistance to carbon dioxide according to the relation: where D, is the molecular diffusivity of COZand D,,, the molecular diffusivity of water vapour.
