Description: | During the month of November 1994, site operations personnel conducted
field comparisons of the temperature and relative humidity sensors in the
EBBRs and the HMI31 portable T/RH meter (with the removable probe). As is
reflected in the home signal output, the automatic exchange mechanism was
disabled in order to conduct the checks.
Measurements were taken every 5 minutes, for a half hour each in the
aspirated radiation shields (the HMI31 was inserted into the EBBR aspirated
radiation shield to provide the same aspiration as the EBBR sensors
received). Measurements of aspirator flow were also recorded. This
information was provided to the mentor. The mentor then compared the field
checks with the data recorded by the EBBRs.
The periods of data and data fields that are incorrect because of the checks
are listed below. Times are those at which the data are reported.

30 minute: 1630, 1700, 1730, 1800
(EDITOR'S NOTE: The following analysis refers to all EBBRs installed in Nov 1994)
Results of the T/RH comparisons:
The combined accuracy of the HMI31 and EBBR temperature sensors
(thermocouples or PRTDs) is +/- 0.4 degrees C. The combined accuracy of the
HMI31 and EBBR RH sensors is +/- 4% for RH less than 80%, and +/- 6% for RH
greater than 80%. The combined accuracy for each pair of EBBR sensors of
the same type is essentially the same as the quantities stated above.
All of the pairs of EBBR sensors show differences that fall within the
stated combined accuracies. Although this sounds wonderful, a few of the
differences are close to the combined accuracy, which, because of the small
differences in temperature being measured (normally smaller than the
magnitude of the combined accuracy) could lead to some incorrect estimation
of sensible and latent heat flux. However, unless there would be substantial
differences of calibration slope of two sensors in a pair, the switching of
height of the sensors every 15 minutes by the automatic exchange mechanism
will remove the offset between the sensors.
The comparisons between the EBBR sensors and the HMI31 T/RH meter showed
much larger differences. The range of differences were: -2.4 to 0.0 degrees
for the thermocouples, -2.1 to 0.1 degrees for the RH probe PRTDs, and -6.6 to
6.7 percent for the RH sensors. Six Thermocouples indicated differences from
the HMI31 greater than the combined accuracy. Seven PRTDs indicated
differences from the HMI31 greater than the combined accuracy. Four RH
sensors indicated differences from the HMI31 greater than the combined
accuracy. The temperature differences (for both thermocouples and PRTDs)
were nearly all of one sign; the HMI31 indicated the greater temperature,
which may suggest a bias in the HMI31 temperature measurement, even though
a dozen differences of +/- 0.2 degrees were measured. Four differences of
zero and only one positive difference (out of 40) were measured. Thirteen of
the 20 RH differences were positive (HMI31 indicating the lower
RH), with the differences near the level of the combined accuracies being
approximately 50% positive and 50% negative. It does not appear that the
HMI31 has a RH bias.
Plots of EBBR sensor/HMI31 differences as a function of time from the
installation of the individual sensors (a range of 10 to 30 months in the
field) shows no obvious pattern of sensor drift with time. This is encouraging. |

* The "end date" is not necessarily in need of definition. The EBBR data

effect on the local shortwave albedo will be longer lasting and could
be said to "end" when the vegetative state recovers to being representative
of similar areas.

Discussion of Problem:
This report is reflective of a change in environmental conditions thought
to be worth noting at E12, Pawhuska, and does not concern any issue of
substandard sensor performance.
A contolled burn was conducted at the the Pawhuska Extened Facillity (E12)
by the Tallgrass Prairie Preserve. The Preserve director, Bob Hamilton,
contacted the ARM SGP Site prior to the activity which allowed Site Operations
to take precautionary steps. Danny Nelson reported the following activities by
Site Operations:
1) Site Ops cut and removed all dried grass within the EF fence and
also to a 10' perimeter around the outside of the fence. Final grass
height was 1-3". This was done on Monday the 17th of March.
2) Tallgrass Prairie Preserve personnel put down a 10' wet line around
our EF prior to the burn on the 20th, so the EF area was not burned.
3) Site Ops had originally planned to deploy a field crew to inspect
the site on the day following the burn. TPP director Bob Hamilton had
agreed to call us the morning of the burn, but didn't actually call us
until this morning; the day following the burn. Due to the short
notification and prior commitment of personnel, Site Ops will not be
able to travel to the site until Monday or Tuesday of next week.
John Shatz was given the following information about the duration of
the burn:
>Bob Hamilton called and indicated that they did a control burn of the
>Tall Grass Prairie yesterday(3-20-97). He indicated that the fire in
>our area lasted between 4:55 PM to 5:40 PM. He also said that they
>plan to put this control burning on a two to three year cycle.
Affect on ARM Data:
Review of the EBBR temperature data (the sensor in the lower position)
shows a dramatic increase of temperature from 26 to 37 Celsius in a
10 minute period. The temperatures appear to have been affected for
approximately 1 hour.
Analysis of the broadband shortwave albedo during this period reveals
changes that appear to be related to the burn. The following is
a listing of the daily average shortwave albedos (caluclated by running a linear
regression fit on the "curve" created by plotting the upwelling shortwave
vs. the downwelling shortwave values from the E12 SIROS broadband instrumentation):
Date Broadband Shortwave Albedo

3-21-97 .141
3-22-97 .143
3-23-97 .148
3-24-97 .147
The grass cutting activity at the EF does not appear to be responsible
for the abledo change on 3-18; this is likely related to the drizzle
and overcast sky conditions in the area on that day. Note that the albedo
recovers to previous values by the next day.
The burn occured late on the 20th, and it appears the albedo after the
burn sustained a more long-lasting decrease in value. Examination of
both the upwelling and downwelling solar irradiance indicates that
the albedo change was a resultant of the decrease in upwelling irradiance,
as the downwelling values were comparable to other sites. |

resulting in the following values being incorrect:
5 minute: wind_s, res_ws
15 minute: wind_s
30 minute: wind_s, res_ws, |
