Problem Description/Change Description.
o For Instrument Problems ONLY,
Identify MODE of Operation: Degraded
o Give a brief explanation with details, attach examples and any supporting
information. This should include a description of analysis leading to
identification of problem and, if known, recommended action.
This is an informational PIF.
On February 23, 1994 the EBBR wind speed sensor at E7, Elk Falls, KS was
frozen to a stationary condition by ice. Invalid data for the time period
indicated is:
30 minute: wind_s, res_ws
15 minute: wind_s
5 minute: wind_s, res_ws.
