Thank you for you responding point-by-point in great detail to the comments by the referees. After this process I feel that the manuscript has been substantially improved and is essentially ready for publication. I have two minor points for you to change before submitting a final version for type-setting.

1) Referee #3 suggested in point 2 that you remove a data point. I agree with your assessment. However, as you say in your response document, please include a brief statement in the final manuscript that you saw no evidence of any parked car, and thus cannot justifiably remove the data point(s).
2) Referee #3 also suggested you clarify the following statement in lines 5-6 of the conclusion of your revised manuscript: "...SOA1 had influences from south whereas SOFA2 had influences from the east and west." Please say why this is the case. As I expect you can't know the reason for this, please state briefly that you do not know the reason. This will help avoid the issue for other readers who may assume you are trying to say something more systematic.
