SGP/EBBR/E26 - Stopped Ventilation Fan

On April 11, 1995, a site operator discovered the right aspirator ventilation
fan of the EBBR to be stopped.  Inspection of the data indicates that this
condition occurred during the two periods shown above; the fan apparently
worked briefly inbetween the periods.  Lack of ventilation of
the temperature and relative humidity sensors attached to the AEM results
in incorrect measurements of air temperature and relative humidity by the
right aspirator probes, and therefore all quantities calculated from them,
including sensible and latent heat fluxes, are incorrect as well.
The quantities that are incorrect for the periods 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, mv_hum_r, tair_r

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