WSA Wind speed average during last
polling interval meters per second
WSMX Wind speed maximum during last
polling interval. Calculated from a
running average of three successive,
one-second wind speed
measurements meters per second
WSMN Wind speed minimum during last
polling interval. Calculated from a
running average of three successive,
one-second wind speed
measurements meters per second
WSSD Wind speed standard deviation
during last polling interval. meters per second
WDA Wind direction average. Calculated
over the polling interval using the
average of one-second wind
direction measurements, excluding
zero wind speed measurements. Degrees from north, ranging
from 0° to 355°
WDSD Wind direction standard deviation.
Calculated over the polling interval
using the average of one-second
wind direction measurements and
the Yamartino algorithm (See B3.1
for details). Degrees
RWS Resultant wind speed. Vector mean
horizontal wind speed calculated
over the polling interval using one-
second measurements including
measurements of zero wind speed. meters per second
RWDA Resultant wind direction average.
Calculated over the polling interval
using one second wind direction
measurements, excluding zero wind
speed measurements. Degrees from north, ranging
from 0° to 355°
