Variation of energy balance in different Green Areas

Abstract

Variation of energy balancing’s Green Area in summer time at Kasetsart University using Eddy covariance technique with the aim to study the variation of the energy balance in different area of green space. The information  need to know are Latent heat flux, Sensible heat flux, Soil heat flux, The data were measured every 30 minutes for basic information in its application for a comparative study of  energy balance of  the different areas of green space in the area to other areas 

 The results showed that the energy balance applied for the latent heat flux as most in the experiment area 1 (grass area 75% water  area 25%) were applied to 62 % and in the experiment  area 2 (grass area 25% water area 75%) were  used as 76 % followed by soil heat flux was 34% and 16% , respectively, in sensible heat flux experiment area 1 (grass area 75% water  area 25%) and experiment area 2 (grass area 25% water area 75%) was used to test the 4% and 8%, while the temperature in the atmosphere, it can be seen that experiment area 1(grass area 75% water  area 25%)  the ambient temperature is higher than the experiment area 2(grass area 25% water area 75%)  with a mean of  33.47 C^o  and 30.71 C^o  The results are summarized ambient temperature varies inversely with the water area .the energy balance is used to latent heat flux so sensible heat flux was below
