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)
