I am an air pollution guy doing on-road measurements of air pollution. I could use some advice on how to assess ambient wind speed and direction while driving.
I need 10 second data and would have gps in the van as one means to determine my location, speed and direction of travel. Wind speeds are likely to be very low vs. the road speeds so I am reluctant to use vector subtraction unless I can be really confident in the met data collection. One thing that would help a lot is advice on such systems and whether any are able to sense and record "north" while underway.
Thanks
