Does the WMO specify the datum for this altitude? I suspect it makes at most 2m of difference, and that a best guess for operational use might be "WGS84 Orthometric Height" -- but I have not been able to find anything that clearly states this. I have been working on finding out the elevation of the desk on which my VP2 console sits to a fraction of a meter. Then I need to model the barometer sensor vs the desk surface to get fully silly. However I think getting it right to 1m matters. -- You received this message because you are subscribed to the Google Groups "weewx-user" group.
