Subject:	SGP/SONDE/C1 - Increased precision for alt, dp, pres, rh, tdry
DataStreams:	sgpsondewnpnC1.b1
Description:	The output precision of the following variables was increased 20060928 alt changed from 1m to 0.1m dp changed from 0.1degC to 0.01degC pres changed from 0.1 hPa to 0.01 hPa RH changed from 1%RH to 0.01%RH tdry changed from .1degC to 0.01degC Note that the increase in precision does not necessarily imply an increase in accuracy. Users are cautioned to continue to use their best scientific judgement when using these or any other data.
Measurements:	sgpsondewnpnC1.b1: Surface dew point temperature(dp) Dry bulb temperature(tdry) Relative humidity inside the instrument enclosure(rh) Retrieved pressure profile(pres) Dummy altitude for Zeb(alt)

Subject:	SGP/EBBR/E4 - Instrument problem
DataStreams:	sgp15ebbrE4.b1, sgp30ebbrE4.b1, sgp5ebbrE4.b1
Description:	Wind direction was flat lining near zero and incorrect.
Measurements:	sgp5ebbrE4.b1: wind direction (relative to true north)(wind_d) standard deviation of wind direction (sigma theta)(sigma_wd) sgp30ebbrE4.b1: wind direction (relative to true north)(wind_d) standard deviation of wind direction (sigma theta)(sigma_wd) sgp15ebbrE4.b1: Wind direction (relative to true north)(mv_wind_d)

Subject:	SGP/SMOS/E7 - Wind sensor binding at low wind speeds
DataStreams:	sgp1440smosE7.b1, sgp1smosE7.b1, sgp30smosE7.b1
Description:	The wind sensor bearings were failing causing the wind speed sensor to report lower than actual wind speeds when the winds were below 2 m/s. The wind monitor was replaced on 05/29/2007 but this failed to correct the problem. Subsequently, the site was flooded and it took some time to re-establish normal operations. The wind sensor was again replaced on 10/30/2007. After replacement the wind data from the SMOS compared more favorably to the co-located EBBR data.
Measurements:	sgp1440smosE7.b1: Time of Minimum Wind Speed(time_min_wspd) Minimum of Wind speed(min_wspd) sgp30smosE7.b1: Wind Speed (vector averaged)(wspd_va) Standard Deviation of Wind Speed(sd_wspd) Mean Wind Speed(wspd) sgp1smosE7.b1: Mean Wind Speed(wspd) Wind Speed (vector averaged)(wspd_va)

Subject:	SGP/SMOS/E13 - RH sensor failure
DataStreams:	sgp1440smosE13.b1, sgp1smosE13.b1, sgp30smosE13.b1
Description:	The T/RH sensor relative humidity data is suspect during this time. Values from this sensor failed the 6-month check and subsequent bi-weekly checks. The RH values were lower by larger than the manufacturer suggested uncertainty of 3%.
Measurements:	sgp1440smosE13.b1: Time of Maximum Relative Humidity(time_max_rh) Time of Maximum Vapor Pressure(time_max_vap_pres) Minimum Relative Humidity(min_rh) Time of Minimum Vapor Pressure(time_min_vap_pres) Maximum Relative Humidity(max_rh) Time of Minimum Relative Humidity(time_min_rh) Maximum Vapor Pressure(max_vap_pres) Minimum Vapor Pressure(min_vap_pres) sgp30smosE13.b1: Standard Deviation of Relative Humidity(sd_rh) Standard Deviation of Vapor Pressure(sd_vap_pres) Vapor Pressure (kiloPascals)(vap_pres) Relative humidity inside the instrument enclosure(rh) sgp1smosE13.b1: Relative humidity inside the instrument enclosure(rh) Vapor Pressure (kiloPascals)(vap_pres)

Subject:	SGP/EBBR/E20 - Reprocess: Wind Direction 20 Degrees Low
DataStreams:	sgp15ebbrE20.b1, sgp30ebbrE20.b1, sgp5ebbrE20.b1
Description:	The EBBR wind direction was found to be misaligned 20 degrees low. This bias should have had no effect on the res_ws or sigma_wd measurements.
Measurements:	sgp30ebbrE20.b1: wind direction (relative to true north)(wind_d) sgp15ebbrE20.b1: Wind direction (relative to true north)(mv_wind_d) sgp5ebbrE20.b1: wind direction (relative to true north)(wind_d)
