Using this site with a Kestrel Portable Weather Station

Air Density Online provides weather data for racing engine tuning and we hope it's useful for anyone using it. However it is one tool in the engine tuner's arsenal and can be used in conjunction with other tools out there. Many times, a portable weather station like a Kestrel unit is used in in addition to or instead of a site like this.

Benefits of a Portable Weather Station

This site gets it's weather information from a third party resource. That data comes from several weather stations around the area of the track and is averaged to provide targeted data. We then calculate air density, density altitude, grains, and other tuning values. While this is a good way to get data while not actually being at the track, it may not completely accurate. That's where a portable weather station comes in. When getting ready for your next run, having current weather data is beneficial for accurate tuning. A portable weather station will give data that is current and local to the point you're standing at.
