difference in wind speed between Meteobridge Pro and Vantage Pro console

Post by TonvG »

I use the MB Pro now for about a month. Looking at the measured wind speed I noticed something. I don't know if others have noticed this too.

Wind is of course very variable. However when calculating the average daily wind speed I found out that the MB is always a bit higher. Also with most of the gusts, although this varies a bit from day to day, as there is always a chance you just missed one.

Have a look on the table

For clarification. The MB values are the daily averages or daily gusts from an export file. The Vantage Pro values are collected via Weatherlink.

One might need to know the archive intervals upon which the averages are worked to have a better understanding of the values? Unless very specifically setup the export file interval and the Weatherlink data interval/timing could be be quite different?

The archive interval in Weatherlink is 10 minutes. So a day average is based upon a lot of readings. The export file is the one with the resolution of days and the setting : [wind0avgwind-avg.1:] for average wind and [wind0wind-max.1:] for the gusts.

For average temperatures and min/max temperatures there is no significant difference between the readings from the export file and Weatherlink.

I think the mistake is in the Weatherlink calculation and especially in the wrong kind of rounding of the data in Weatherlink for the wind readings. But you only get aware of that once you are able to compare the data.
