The WA command is executed by the ASOS at an interval that ranges
from 1 to 30 seconds. For the WA command, WMT700 responds to the
ASOS interrogation poll within 250 milliseconds of receiving the

WA — Fetch Averaged Wind Speed and Direction
This command requests the averaged wind speed and direction message
with peak winds.
WA
The response to the WA command consists of the averaged wind speed
and direction data, peak wind speed, and associated direction. The
average wind speed is a scalar running average of the fundamental
1-second interval wind speed measurement made by WMT700. For a
description of the data message, see section WS425 F/G ASOS Data
Message on page 48.
You can set the wind averaging time and gust time with the wndAvg and
wndGustTime parameters. Set the wndVector parameter to 0 to use
scalar averaging.
The command also fetches the WMT700 status, the averaging time for
average and peak wind speed and wind direction, and signal quality.

This command requests the verbose Built-In Test (BIT) results.
WS
