SGP/EBBR/E8 - Invalid data due to AEM fuse blow out at E8

On December 17, 1993, before 1100 GMT, the fuse in the AEM (Automatic
Exchange Mechanism) of Coldwater, KS (E8) EBBR blew out.  The AEM remained
nonfunctional until the fuse was replaced just before 1700 GMT on
December 29, 1993.  During the 1000 GMT half hour on December 17 the AEM
was hung up; this is clear from the home signal.  These situations resulted in
the following invalid data:

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

15 minute: rr_thum_r, rr_thum_l, mv_hum_r, mv_hum_l, mv_home, 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, home_15, home_30

Bowen, h, and e can not be recalculated from the 15 minute and/or 5 minute data
since we cannot determine the position of the sensors on the AEM from the home
signal; home signal is near zero when there is no power to the AEM.
