SGP/EBBR/E20 - Blown fuse in AEM at E20

On October 30, 1993, before 1300 GMT, the fuse in the AEM (Automatic
Exchange Mechanism) of Meeker, Ok (E20) EBBR blew out.  The AEM remained
nonfunctional until the fuse was replaced just before 1600 GMT on
November 12, 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


If the biases of the sensors were know, bowen, h, and e could be
recalculated from the 15 minute and/or 5 minute data.  Since we will not
have any idea of what those biases are until an annual calibration of the
sensors can take place (which may be months away), the recalculations
cannot be performed at this time.  Furthermore, it may be invalid to use
sensor biases, if determined too far removed in time, due to the gradual
calibration drift of some of the sensors.
