Average soil heat flow, sensible heat flux, and latent heat flux are also affected; these can be recalculated using the remaining good sets of soil sensors as follows: The heat fluxes can be recalculated by using soil sets 1, 2, 4, and 5 as follows: ave_shf = (g1 + g2 + g4 + g5)/4 e = -(q + ave_shf)/(1 + bowen) h = -(q + e + ave_shf)

Subject:	SGP/EBBR/E12 - Reprocess: Soil Moisture 4 and 5 Incorrect
DataStreams:	sgp30ebbrE12.a1, sgp30ebbrE12.b1
Description:	Soil moisture measurements from sets 4 and 5 were incorrect, leading to many other incorrect measurements calculated using them. Average soil heat flow, sensible heat flux, and latent heat flux are affected; these can be recalculated using the remaining good sets of soil sensors as follows: ave_shf = (g1 + g2 + g3)/3 e = -(q + ave_shf)/(1 + bowen) h = -(q + e + ave_shf) Note: D020717.6 reports Soil temperature sensor #3 was also bad during this time, but for the very specific records affected by the soil moisture #4 and #5 reporting incorrectly, soil temp #3 was okay.

In this particular case, some of the data is suspect when the battery voltage is below 11.0 volts. Soil Heat Flow #3 is normally affected first, with other measurements following at lower voltages.

Subject:	SGP/EBBR/E12 - Improved EBBR CR10 Program
DataStreams:	sgp30ebbrE12.b1
Description:	Effective 20050329.1830, the EBBR.E12 CR10 program was revised to improve the quality of the primary measurements as follows: 1) An RMS procedure is used to determine max and min limits of acceptable soil heat flow. This is applied to the individual soil sets. Measurements outside the limits are rejected and the measurements within the limits are used to calculate the average soil heat flow. 2) Max and min limits are used to determine incorrect values of net radiation, sensible heat flux (h), latent heat flux (e), and automatic exchange mechanism (AEM) signal. If AEM signal is outside the limits, h and e are set to 999s. If net radiation is outside the limits, h and e are set to 999s. If h or e are outside the limits, h and e are set to 999s. Virtually no incorrect soil measurement will affect the primary measurements of h and e. By setting h and e to 999s, it can be easily seen that the primary variables are incorrect; no other interpretation is possible. Prior to 20050329, the improved CR10 program was NOT in effect. DQRs have been submitted for known instances of incorrect soil measurements which affected the quality of the primary measurements of h and e. Note: the DQR begin date is the begin date of the sgp30ebbrE12.b1 data stream. The earlier version of the CR10 program was also used on previous EBBR datastream names (e.g. sgp30ebbrE12.a1).

Description:	DQR No: Platforms: sgpsirosE12 sgpebbrE12 Subject: Controlled burn at E12 on 3/20/97 and affected data Date Submitted: 3/31/97 Submitted By: Mike Splitt ___ Instrument Mentor ___ EST Member ___ Science Team Member _x_ Other _Site_Scientist_Team_ For questions or problems, please contact the ARM Experiment Center at 509-375-6898 or via email at problems@arm.gov. Platform/Measurement: What level data: (raw,a0,a1,b1,c1 etc): all levels What location was the data collected at: sgp E12 Period of time in question Begin Date 3/20/97 Time 22:55 (GMT) End Date * Time : (GMT) * The "end date" is not necessarily in need of definition. The EBBR data appears to be directly affected for a period of about one hour. The 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. Data should be labeled: ___ questionable ___ All data fields affected ___ incorrect ___ Only some data fields affected ___ wrong calibration _x_ others 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 ________ ____________________________ 3-14-97 .171 3-15-97 .171 3-16-97 .169 3-17-97 .166 3-18-97 .135 3-19-97 .171 3-20-97 .174 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.

Subject:	SGP/EBBR/E12 - Wind Direction Sensor Malfunctions
DataStreams:	sgp15ebbrE12.a1, sgp30ebbrE12.a1, sgp5ebbrE12.a0
Description:	For much of the period above, a malfunction in the E12 EBBR wind direction sensor (insect larvae shorting out the circuit board) caused incorrect values for 5 minute res_ws, wind_d, and sigma_wd, 15 minute mv_wind_d, and 30 minute res_ws, wind_d, and sigma_wd. Wind direction normally indicated north (near 0 or 360 degrees); there were some times during the period when wind directions looked good, but the lack of variation in direction and sigma implies that the data is suspect. Therefore, it would be wise to flag all of the values listed above during the entire time period as incorrect. The wind direction sensor (S/N 3081) was replaced with S/N 3042 at 1515 GMT on June 8, 1997.

DataStreams:	sgp15ebbrE12.a1, sgp30ebbrE12.a1, sgp5ebbrE12.a0
Description:	The upper dome of the EBBR net radiometers was punctured. After the puncture, water collected in the top and/or bottom dome. The water was removed and the dome was replaced during PM visits. In some cases, the puncture and water resulted in incorrect data. Comparison with net radiation values from surrounding EBBR sites and the SIRS is neccesary to determine if the EBBR net radiation data are correct or incorrect. It is often difficult to tell from the data when the punctures occurred, but they would have existed for no more than 2 weeks, since the domes are checked during each two-weekly PM visit. Incorrect net radiation data results in the latent heat flux and sensible heat flux also being incorrect.
