3. Net Radiance (Rn) = 125.58 Wm -2 Sensible Heat Flux (H) = 17.15 Wm -2 Ground Heat Flux (G) = 34.99 Wm -2 Latent Heat Flux (λE) = 73.44 Wm -2 (Rn-G)125.58-34.99 = 90.59 (H+ λE)17.15+73.44 = 90.59 0

4. Temperature (T d ) = 17.23 ˚C Dew point Temperature (T dew ) = 3.60 ˚C

5. Bowen Ratio (B) = 0.233521 H/Rn= 0.136565 Canopy Resistance (r sc ) = 60 sm -1 Roughness Length (z 0 ) = 0.050 m Friction Velocity (U * ) = 0.138 m/s

6. Increasing the value of Canopy Resistance and / or Roughness Length Latent Heat Flux tends to drop as the day progresses as the air becomes warmer and Relative Humidity falls.
