Subject:
SGP/EBBR/E12 - Invalid data due to blown AEM fuse at E12
DataStreams:sgp5ebbrE12.b1, sgp30ebbrE12.b1, sgp15ebbrE12.b1
Description:
On December 20, 1993, before 0730 GMT, the fuse in the AEM (Automatic
Exchange Mechanism) of Pawhuska, OK (E12) EBBR blew out.  The AEM remained
nonfunctional until the fuse was replaced just before 1500 GMT on
December 22, 1993.  This situation 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.
