SGP/EBBR - EBBR E20 Data Incorrect from SHF #5

something, since the problem began during J-panel changeout the 4/7/99 PM.
At the 7/21/99 PM, the reference temperature was repaired and reseated.  At
that time the SHF #5 data became correct again; the two events are probably
related only in that other connections, including that of the SHF #5, were
probably reseated at the same time.  The report of the PM activity is not
detailed enough to determine the exact causes and fixes.

The incorrect SHF #5 data can be identified by it being an order of 
magnitude larger than the values from the other soil heat flow sensors.

Affected data are:

5 minute:  none
15 minute: mv_hft5
30 minute: shf5, c_shf5, g5, ave_shf, e, h

SGP/EBBR - EBBR E20 Thermocouple Data Incorrect

Left and right thermocouple air temperature data are incorrect during the
replacement of the right thermocouple.

Affected data are:

5 minute:  tair_bot, tair_top
15 minute: tai_r, tair_l
30 minute: tair_bot, tair_top, e, h, bowen

SGP/EBBR - EBBR E19 Wind Speed Incorrect

The anemometer cups were frozen stalled during the period.

The following values were therefore incorrect:

5 minute:  wind_s, res_ws
15 minute: wind_s
30 minute: wind_s, res_ws

SGP/EBBR - EBBR E15 Anemometer Cup Off, Wind Speed Incorrect

An anemometer cup fell off.

SGP/EBBR- EBBR E15 Air Temperatures Incorrect

When the reference temperature sensor was being replaced, the left and
right thermocouple air temperatures and humidity probe temperatures 
were incorrect.

Affected data values were:

5 Minute:  tref, tair_top, tair_bot, thum_top, thum_bot, vp_top, vp_bot
15 minute: rr_tref, rr_thum_l, rr_thum_r, tair_r, tair_l

SGP/EBBR - EBBR E18 Right Humidity Incorrect

After the 3 December 99 lightning strike, the humidity portion of the 
right T/RH probe drifted downwards at times, causing vapor pressure 
gradients to be incorrectly measured.  Therefore, sensible and latent
heat fluxes were also incorrect.  Since much of the data from the period
is missing (because of latent effects of the lightning strike), little
data is actually affected. 

The affected data values were:

5 minute:  hum_top, hum_bot, vp_top, vp_bot
15 minute: mv_hum_r
30 minute: hum_top, hum_bot, vp_top, vp_bot, bowen, h, e

A bad capacitor on the J-panel caused left air temperature, and thus other measurements to 
be incorrect.

SGP EBBR E19 - E19 EBBR Soil Heat Flow #1 Sign Reversed

The sign was reversed (heat flow plate #1 was installed upside down), causing incorrect 
measurements, as indicated.

The average soil heat flow can be recalculated by using an average of soil sensor sets 
2-5.  The recalculated average soil heat flow can then be used to recalculate latent and 
sensible heat fluxes.
