Subject: | SGP/EBBR/E13 - Failed Right Humidity Probe |
DataStreams: | sgp5ebbrE13.b1, sgp15ebbrE13.b1, sgp30ebbrE13.b1, sgp5ebbrE13.00 |
Description: | A lightning strike to the central cluster area on 17 July 1995 caused failure of several EBBR sensors including the right humidity probe. On July 24th, site operations removed the right humidity probe SN 460412 and replaced it with SN 460428 In less than a day the right humidity probe output soared to over 113% and has hovered around 112% since. I consider all right probe values to be incorrect due to this behavior. Without a properly functioning right humidity probe, all values of top and bottom relative humidity, top and bottom vapor pressure, Bowen ratio, and latent and sensible heat fluxes are incorrect. A working spare relative humidity probe was not available at that time. The probe was replaced with a working, calibrated probe on 22 September 1995 at about 2108 GMT. I have the examined the data since the day of the replacement and find that the new probe is working well. All E13 EBBR measurements are presently correct. The old probe S/N was 460428, the new S/N is 460413. |
