Investigate average wind reporting difference #150

Open akrherz opened 6 years ago

akrherz commented 6 years ago

IEM User reported to me a difference in reported average wind

from autoplot 140 10.1mph

from dynamic windrose generator 9.8 mph

We should likely match a bit closer than that :/

The autoplot uses whatever daily summary information is found within IEMAccess, this value is computed based on time weighted averaging. The dynamic windrose generator does an equal weight average of hourly data. Making them match would be nice, but would take some effort.
