Wddatabase Wind Fields

What do the wind 3 fields exported to wd.mdb represent.

Current Windspeed
Current Gustspeed
Wind Direction

Are they instanteous , average or maximum readings for the period (1 min)?

Whether the wind direction is an average or the last reading for the period is what I would like to find out.

the gust is the max gust in the last minute, the average is the 1 minute averge speed, and so is the direction (1 minute average)
