One option would be to put this in [StdCalibrate]
[StdCalibrate]
[[Corrections]]
windSpeed = 0 if windSpeed is None else windSpeed
That will actually save the value 0 (zero) in your database.
Another option, not so drastic, is to interpret None as zero in your
templates. Instead of
<p>The current windspeed is $current.windSpeed</p>
use
<p>The current windspeed is $current.windspeed.format(None_string="0")</p>
