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: Temperature, air, 25-m height, 30-min intervals(temp_25m) Pressure, vapor, 25-m height, 30-min intervals(vap_pres_25m) sgp30twr10xC1.b1: Temperature, air, 25-m height, 30-min intervals(temp_25m) Pressure, vapor, 25-m height, 30-min intervals(vap_pres_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: Pressure, vapor, 60-m height, 30-min intervals(vap_pres_60m) Humidity, relative, 25-m height, 30-min intervals(rh_25m) Humidity, relative, 60-m height, 30-min intervals(rh_60m) Pressure, vapor, 25-m height, 30-min intervals(vap_pres_25m) sgp30twr10xC1.b1: Humidity, relative, 25-m height, 30-min intervals(rh_25m) Pressure, vapor, 60-m height, 30-min intervals(vap_pres_60m) Humidity, relative, 60-m height, 30-min intervals(rh_60m) Pressure, vapor, 25-m height, 30-min intervals(vap_pres_25m)

Subject:	SGP/TWR/C1 - Tower SE-side lowered for maintenance
DataStreams:	sgp1twr10xC1.b1, sgp30twr10xC1.b1
Description:	The southeast side tower carriage was lowered for maintenance and/or data are off-scale during maintenance.
Measurements:	sgp1twr10xC1.b1: Pressure, vapor, 60-m height, 30-min intervals(vap_pres_60m) Humidity, relative, 25-m height, 30-min intervals(rh_25m) Pressure, vapor, 25-m height, 30-min intervals(vap_pres_25m) Humidity, relative, 60-m height, 30-min intervals(rh_60m) Temperature, air, 25-m height, 30-min intervals(temp_25m) Temperature, air, 60-m height, 30-min intervals(temp_60m) sgp30twr10xC1.b1: sd_vap_pres_25m Pressure, vapor, 60-m height, 30-min intervals(vap_pres_60m) Temperature, air, 60-m height, 30-min intervals(temp_60m) sd_rh_25m Pressure, vapor, 25-m height, 30-min intervals(vap_pres_25m) sd_temp_25m sd_rh_60m sd_temp_60m sd_vap_pres_60m Humidity, relative, 25-m height, 30-min intervals(rh_25m) Temperature, air, 25-m height, 30-min intervals(temp_25m) Humidity, relative, 60-m height, 30-min intervals(rh_60m)

Subject:	SGP/TWR/C1 - Southeast Side (10X) Temperature and RH Spikes
DataStreams:	sgp1twr10xC1.b1, sgp30twr10xC1.b1
Description:	Southeast side 25 m and 60 m (10X datastreams) carriage connectors may not have been well connected; temperatures and relative humidities spiked sometimes. This problem occurred after the carriages were lowered on 12/04.
Measurements:	sgp1twr10xC1.b1: Pressure, vapor, 60-m height, 30-min intervals(vap_pres_60m) Humidity, relative, 25-m height, 30-min intervals(rh_25m) Pressure, vapor, 25-m height, 30-min intervals(vap_pres_25m) Humidity, relative, 60-m height, 30-min intervals(rh_60m) Temperature, air, 25-m height, 30-min intervals(temp_25m) Temperature, air, 60-m height, 30-min intervals(temp_60m) sgp30twr10xC1.b1: sd_vap_pres_25m Pressure, vapor, 60-m height, 30-min intervals(vap_pres_60m) Temperature, air, 60-m height, 30-min intervals(temp_60m) sd_rh_25m Pressure, vapor, 25-m height, 30-min intervals(vap_pres_25m) sd_temp_25m sd_rh_60m sd_temp_60m sd_vap_pres_60m Humidity, relative, 25-m height, 30-min intervals(rh_25m) Temperature, air, 25-m height, 30-min intervals(temp_25m) Humidity, relative, 60-m height, 30-min intervals(rh_60m)
