Subject:
SGP/EBBR/E12 - Stopped Ventilation Fan
DataStreams:sgp5ebbrE12.b1, sgp30ebbrE12.b1, sgp15ebbrE12.b1
Description:
On August 4, 1994, a site operator discovered the ventilation fan of the
EBBR to be stopped; the fan guard was clogged with animal remains.
Inspection of the EBBR data from Pawhuska, OK, E12 indicates that this
condition occurred from July 22 through August 4.  Lack of ventilation of
the temperature and relative humidity sensors attached to the AEM results
in questionable measurements of air temperature, relative humidity, and all
quantities calculated from them, including sensible and latent heat fluxes.
The quantities that are questionable for the period indicated are:

5 minute:  tair_top, tair_bot, thum_top, thum_bot, hum_top, hum_bot,
           vp_top, and vp_bot

15 minute: rr_thum_r, rr_thum_l, mv_hum_r, mv_hum_l, tair_r, tair_l

30 minute: tair_top, tair_bot, thum_top, thum_bot, hum_top, hum_bot,
           vp_top, vp_bot, bowen, e, h
