Subject:	SGP/TWR/C1 - Tower 60m SE Temperature Flat
DataStreams:	sgp1twr10xC1.a1, sgp1twr10xC1.b1, sgp30twr10xC1.a1, sgp30twr10xC1.b1
Description:	During these periods the Southeast side 60 m Temperature was unchanging (flat). This can occur for several consecutive minutes, but not for as long as occurred here. Therefore the Temperature and Vapor Pressure measurements are suspect.
Measurements:	sgp1twr10xC1.b1: Relative humidity at 60 m(rh_60m) Vapor pressure at 60 m(vap_pres_60m) sgp30twr10xC1.a1: Standard Deviation of 60 m Vapor Pressure(sd_vap_pres_60m) Vapor pressure at 60 m(vap_pres_60m) Relative humidity at 60 m(rh_60m) Standard Deviation of 60 m Relative Humidity(sd_rh_60m) sgp30twr10xC1.b1: Vapor pressure at 60 m(vap_pres_60m) Standard Deviation of 60 m Vapor Pressure(sd_vap_pres_60m) Relative humidity at 60 m(rh_60m) Standard Deviation of 60 m Relative Humidity(sd_rh_60m) sgp1twr10xC1.a1: Vapor pressure at 60 m(vap_pres_60m) Relative humidity at 60 m(rh_60m)

Subject:	SGP/TWR/C1 - Temperature Sensor Not Connected to Datalogger
DataStreams:	sgp1twr10xC1.b1, sgp30twr10xC1.b1
Description:	One of the southeast side 25 m Temperature sensor leads was pulled out from the CR10X datalogger terminal strip.
Measurements:	sgp1twr10xC1.b1: Vapor pressure at 25 m(vap_pres_25m) Temperature at 25 m(temp_25m) sgp30twr10xC1.b1: Vapor pressure at 25 m(vap_pres_25m) Temperature at 25 m(temp_25m)

Subject:	SGP/TWR/C1 - Southeast Side RH Too Large
DataStreams:	sgp1twr10xC1.b1, sgp30twr10xC1.b1
Description:	The T/RH probes installed on the 25 m and 60 m levels of the southeast side of the tower on 8/15/03 gave RH readings that were too large for RH above 65%. The difference between the west and southeast side RH was within the combined accuracies of the sensors up to about 80% RH. Above 80% RH the southeast side RH was much larger, with the difference increasing to 10% larger (or more) at 100% RH. The vapor pressure from the southeast side (calculated with RH) was also too large. The probes were replaced on 2/10/04 and the two sides of the tower now agree fairly well, with RH not exceeding 100% during saturation.
Measurements:	sgp1twr10xC1.b1: Relative humidity at 60 m(rh_60m) Vapor pressure at 25 m(vap_pres_25m) Relative humidity at 25 m(rh_25m) Vapor pressure at 60 m(vap_pres_60m) sgp30twr10xC1.b1: Vapor pressure at 25 m(vap_pres_25m) Vapor pressure at 60 m(vap_pres_60m) Relative humidity at 60 m(rh_60m) Relative humidity at 25 m(rh_25m)
