Hey all,

I was looking at today's winds (wondering what I missed after I returned from the Edutrip!) and I saw a couple suspicious drops in wind speed.

Did you get some icing up on the pitot tube in the sub-zero weather? Just curious.

Yes we had some icing. I will explain more in my comment tonight.

HI Ryan:

I read your comments, that's pretty interesting information. I work for a Chem. Mfg. Company here that Mfgs. tons and tons of Methanol, among many other nasty chemicals. Precautions are always needed when dealing with hazards. I undergo constant training in order to keep up with all of the regulatory information.

Hi Ryan, How does your wind velocity instrumentaion compensate for the elevation?? I have used a pitot tube and manometer to measure air speed for ventilation testing and had to compensate for temperatures but never for barametric pressures. Was wondering if you have to do the conversions from VP to speed?? wing-it
