Wind Rose
Vista Data Vision has 3 different Wind Roses to analyze Wind Direction Data: Basic Wind Rose, Distribution Wind Rose and Filter Wind Rose.
Wind Rose is a clever way of analyzing data that is related to wind direction. Not only is Wind Rose perfect to plot the classical Wind Rose, e.g. wind speed against wind direction, but actually any sensor against wind direction. As an example, check where from the precipitation is coming, or air temperature or air humidity, or where from the ambient pollution is coming from, like Dust, NO, NOx, SO2, H2O etc.
How does it work?
- On a page with Wind Direction, click on its graph to enlarge it.
- On the top menu bar, choose any of the 3 Wind Rose options.
- Choose filter variable, choose time period.
- That's it! And its works both on the VDV web interface as on the db.data browser desktop software.
Basic Wind Rose
Shows the wind distribution for a specific time period.
Distribution Wind Rose
The Distribution Wind Rose allows you to view the distribution of a second Variable in connection to Wind Direction.
Filter Wind Rose
Filter Wind Rose is a powerful tool that allows you to determine a relationship between Wind Direction and a second measurement.
