SGP/EBBR/E20 - Reprocess: E20 Soil Probes #3 Cables Cut
DataStreams:sgp15ebbrE20.a1, sgp30ebbrE20.a1
Description:
The cables going to #3 soil temperature, moisture, and heat flow probes 
were cut by a mower on 11 June 1997 and were repaired on 16 July 1997.  
Data for the temperature probe was offscale, for the soil moisture probe 
was a constant 10.1 (close to the actual), and for the soil heat flow 
was large negative during the period. 

The following are the data quantities that were affected:

15 minute: rr_ts3, mv_hft3, r_sm3

30 minute: ts3, ces3, shf3, c_shf3, cs3, g3, ave_shf, e, h

Sensible, latent, and soil heat fluxes can be recalculated using the 
values from probes 1, 2, 4, and 5, as follows.

ave_shf = (g1 + g2 + g4 + g5)/4

e = -(q + ave_shf)/(1 +bowen)

h = -(e + ave_shf +q)
Measurements:sgp30ebbrE20.a1:
  • latent heat flux(e)
  • soil heat flow, site 3(g3)
  • 0-5 cm change in soil heat storage with time, site 3(ces3)

  • h(h)
  • 5 cm soil heat flow, site 3(shf3)
  • 5 cm soil heat flow corrected for soil moisture content, site 3(c_shf3)

SGP/EBBR/E20 - 3 Month Check
DataStreams:sgp15ebbrE20.a1, sgp30ebbrE20.a1, sgp5ebbrE20.a0
Description:
During EBBR 3 month checks the Automatic Exchange Mechanism is disabled
(reflected by home signals near zero) so that the two aspirator units can be
placed at the same height.  The measurements during these periods 
do not produce correct outputs of bowen ratio (bowen), sensible heat flux
(h), or latent heat flux (e), nor do the air temperature and relative 
humidity measurements indicate correct gradients.  Checks performed before 
or after the AEM is disabled also lead to some incorrect data.  Incorrect 5,
15 minute and half hour data occurs for the period above.

Description:
During EBBR 6 month checks (formally called 3 month checks) the Automatic 
Exchange Mechanism is disabled (reflected by home signals near zero) so that
the two aspirator units can be placed at the same height.  The measurements
during these periods do not produce correct outputs of bowen ratio (bowen), 
sensible heat flux (h), or latent heat flux (e), nor do the air temperature

SGP/EBBR/E20 - Data Incorrect
DataStreams:sgp15ebbrE20.a1, sgp30ebbrE20.a1, sgp5ebbrE20.00, sgp5ebbrE20.a0
Description:
Version 6 of the CR10 program was installed during this period instead of
version 7 (the initial version 7 program did not work).  The calibrations 
and coefficients in version 6 were incorrect; therefore all 
data during this period is of questionable quality and e and h are clearly
incorrect.  The correct version 7 program was installed on 29 Dec 1998.

SGP/EBBR/E20 - Pressure Low
DataStreams:sgp15ebbrE20.a1, sgp30ebbrE20.a1, sgp5ebbrE20.a0
Description:
The pressure sensor values dropped several kPa on 13 January 1999 because 
of a sensor malfunction and remained that way until the sensor was 
replaced on 10 February 1999.  Comparison of the pressure before and after
the problem period shows that Bowen ratio was underestimated by 
approximately 6% during the period, resulting in a 6% overestimation of
latent heat flux and a 6% underestimation of sensible heat flux.  
Adjustment of the flux data during the period by these amounts should be
made by the data user.

  • latent heat flux(e)
  • top vapor pressure(vp_top)
  • ratio of sensible/latent heat fluxes (Bowen ratio)(bowen)
