SGP/EBBR/E13 - Sensible and Latent Heat Fluxes Incorrect (AEM failure)

The AEM was stuck in the home 30 position most of this period.

Therefore, the sensible and latent heat fluxes are incorrect during most of this period.

• Right air temperature(tair_r)

• Temperature of bottom humidity sensor chamber(thum_bot)
• top vapor pressure(vp_top)

SGP/EBBR/E20 - Soil Temperature and Soil Moisture  #4 Measurements Incorrect

The ts4 sensor reported 99999 values because the sensor leads were loose.  Soil moisture 
#4 reported low values (steady 16%) during this time period.

The sensible and latent heat fluxes were not affected by this problem, only
soil temperature and soil moisture #4.  See soil temperatures and soil moistures from sets 
#2, #3, and #5 for correct values (note: soil temperature #1 was having problems during 
the same time).

SGP/EBBR/E7 - Data Missing

Data was missing because of a communication problem.  However, previously
missing data from 10/07-18 was recovered from the EBRR storage module and ingested, 
thereby reducing the data lost period significantly.

SGP/EBBR/E13 - Fluxes Incorrect

The AEM has not been reaching the home_30 position fully a few times a day on most days, 
resulting in zero home_30 measurements.

zero.

occurred.

caused the net radiation measurements to be biased low, and resulting in sensible and 
latent heat flux being low also.

• h(h)
• latent heat flux(e)
• net radiation(q)

• Net radiation(mv_q)
