SGP/EBBR/E26 - Wind Speed Cups Frozen

Freezing rain, snow, and below freezing conditions during the night of 10-11
November 1995 resulted in the wind speed sensor cups becoming frozen in a
stopped state at E26, Cement, OK on early 11 November 1995.  When temperatures
rose to almost freezing under cloudless skies later in the day, the ice thawed
and the cups were free to turn again.

Measurements affected by the stalled wind speed sensor include:

5 minute:  wind_s, res_ws

15 minute: wind_s

30 minute: wind_s, res_ws

• Wind speed vector mean(wspd_vec_mean)
• Wind speed arithmetic mean(wspd_arith_mean)

• Wind speed arithmetic mean(wspd_arith_mean)

• Wind speed arithmetic mean(wspd_arith_mean)
• Wind speed vector mean(wspd_vec_mean)
