Writing Feedback / 'behaviour of the wind-flow and concentration fields' - paragraph. [3]

Hi for all,

As I am writing my thesis and I would like to write it in english language, I would like to ask some persons who have english language as their mother-tongue to correct me few paragraphs if possible. I have some difficulties to write in english particularly for few sentences (Sometimes I translate from french, and unfortunately in english it is not the correct way to said it when translated directly).

Here is the paragraph:

It should be noted that only the main obstacle upstream of the emitter building has been taken into account, namely a tower forth time higher, since it has been judged that only this tower could have major effects on the overall behaviour of the wind-flow and concentration fields around the building of interest.

Thanks a lot,

Cherif
