Let’s have a good track weather (bar, temp, humidity, corrected altitude) discussion

Thank you for doing this. I was trying to do a layman's description on Johns other post.
Using a inexpensive weather station,using the DA chart aircraft pilots use, and chart temp,pressure and humidity.
I have been out of the racing game for awhile. Just a bit fuzzy. For bracket racing you try to do the same every run for consistency .Wind direction and speed,Engine temp,Tire pressure and the like.

I was old school and used a on-off switch for my electric waterpump to be at the same temp every run when at the tree.
