Subject:	TWP/C1 - Incorrect elevation reported in Manus Data
DataStreams:	twpsondewnpnC1.a1
Description:	(From Bill Clements) We have been using 6m MSL as the station elevation of Momote (Manus). This was based on information posted near the station barometer in the Momote Weather Service Office. It turns out that the official WMO station elevation for Momote is 4m MSL and the upper air elevation is 5m MSL. All Manus instruments except the sonde station are at 4m MSL. The sonde launching station is at 5m MSL.

Subject:	SGP/SONDE/B1 - Bad sounding data (incorrect calibration?)
DataStreams:	sgpsondewnpnB1.00, sgpsondewnpnB1.a0, sgpsondewnpnB1.a1
Description:	I'm not sure what happened here but the temperature data for this sounding clearly are wrong. Along with the missing humidity data and the problems the operator reported with his previous sounding it looks as if all the data in this file are bad. It may be that the sensor was damaged at launch (it was very windy).

Subject:	TWP/C2 Installation
DataStreams:	twpsondewnpnC2.00, twpsondewnpnC2.a0, twpsondewnpnC2.a1
Description:	The Nauru ARCS was installed during the period September-November 1998. Data were being collected by the end of October, but for the first several weeks of November, the site was undergoing considerable change, so data from that period should be used with caution. The official site dedication occured on November 20. Most on-site activity ended following the dedication so we will consider November 20 to be the beginning of the Nauru operations. The last members of the installation team left Nauru on November 24.

Subject:	SGP/SONDE/B4 - Soundings contaminated by interference
DataStreams:	sgplssondeB4.c1, sgpqmemwrcolB4.c1, sgpsondewnpnB4.a1, sgpsondewnpnB4.b1
Description:	These five soundings, done in succession on 11/07/2002 as part of the SCM/IOP are contaminated by interference. I can't tell whether the problem has to do with improper tuning of the radiosondes, inadequate frequency separation among radiosondes launched from different locations, or some other operator problem. I suspect that there is an operator component to the difficulty because the surface pressure is given as an unreasonably low 896.6 hPa on the 1730 sounding and 886.1 hPa on the 2331 sounding. This may indicate that the ground station was locked another station's radiosonde rather than on the B4 radiosonde.

Subject:	SGP/SONDE/B4 - Possible interference in B4 sounding 20021110.1729
DataStreams:	sgpsondeB4.00, sgpsondewnpnB4.a1, sgpsondewnpnB4.b1
Description:	There is a strange inversion aloft in the subject sounding. The temperature goes from -56.3 degC to -51.5 degC in less than two minutes (approximately .72 km). This is somewhat below the estimated tropopause height. I suspect this may be an interference problem, but note that both the recorded pressure and RH values are reasonably continuous. More accurate assessment would require analysis of the absolutely raw binary data; something that would require effort beyond the limits of my IM funding.

DataStreams:	twpsondewnpnC1.a1, twpsondewnpnC1.b1
Description:	The RH values from the surface to approximately 11.5 km oscillate between reasonable values and zero. This is apparently caused by a failure in the RH sensor heating process. Although the oscillation stops when the heating stops (at temperatures below ~ -45degC) I think the values must be viewed as suspect.

DataStreams:	twpsondewnpnC1.a1, twpsondewnpnC1.b1
Description:	It appears that the RH sensor heating circuit failed during this portion of the sounding (approximately between 5km and 10km). The RH oscillates rapidly between low (~5 %RH) and not so low (~50 %RH) and the oscillation seems to stop when the temperature is below ~35 degC. According to Vaisala these are symptoms of failure in the ASIC (application specific integrated circuit) that controls the heating.

Subject:	TWP/SONDE/C2 - Strange problem with data -
DataStreams:	twpsondeC2.00, twpsondewnpnC2.00, twpsondewnpnC2.b1
Description:	This is very strange. The data has what appears to be a pressure jump at launch (from 1007.2 to 956.5 hPa) but the sounding temperature and RH data clearly look to be interpolated between the surface and tropopause. By examining the absolutely raw data, I found that the system assigned an elapsed time of 408 seconds (since system start up) to the launch point, but there is no raw data between 410 and 532 seconds. The raw pressure value at 410 seconds is 1007.6 hPa and that at 532 seconds is 40.9 hPa! Unless this sounding was done by using a rocket-powered balloon (maybe even then), it would be impossible for the sonde to get to 40.9 hPa in 2 minutes. Because the apparent gap is only two minutes, the system was able to interpolate but is not sophisticated enough to understand that the limits of the interpolation are unreasonable. I can't imagine what went wrong - I've not seen anything like this before.

Description:	It appears that the RH sensor heating circuit failed during this portion of the sounding (approximately between 0km and 12km). The RH oscillates rapidly in a 20% range and the oscillation seems to stop when the temperature is below ~45 degC. These are symptoms of failure in the ASIC (application specific integrated circuit) that controls the heating.

DataStreams:	twpsondewnpnC2.b1
Description:	It appears that the RH sensor heating circuit on this sonde failed about 24 minutes into the flight. The RH values look reasonable, though somewhat noisy, from the surface to approximately 6.9 km (439 hPa) at which point they begin to oscillate between 0 and 100 %. This behavior stops when the sonde reaches approximately 11.5km (232 hPa) when the air temperature drops below -40 degC. The oscillation stops at that point, though the RH remains higher than might be expected even under supersaturated conditions.

Subject:	TWP/SONDE/C2 - Operator used wrong calibration tape
DataStreams:	twpsondewnpnC2.b1
Description:	It appears as though the opperator used the wrong calibration tape for this sounding. The primary symptom is a jump in temperature from a surface value of 30.1 degC to the first value aloft of 61.0 degC. Secondly, the recorded serial number for this sounding is Z1430179 which is the same serial number recorded for the previous sounding. This problem points to three failures of procedure (I have notified TWP site ops by e-mail). The first failure is using the wrong tape. The second failure is not checking the radiosonde values before launch which relates to the third failure of not entering the radiosonde values as the surface values of the sounding.

Description:	Vaisala has confirmed ARM findings of an apparent dry bias in the relative humidity measured by RS-80H radiosondes. The cause of the dry bias is thought to be contamination of the humidity sensor by volatile organic substances originating from some plastic parts of the radiosonde. The amount of contamination is a function of the time between the date of sonde manufacture and its use. All RS-80H sondes manufactured before week 34 of 1998 will show this bias. After week 34 of 1998 Vaisala changed its packaging to reduce, but not eliminate the contamination problem. Starting with RS-80 radiosonde manufactured in late June 2000 Vaisala enclosed the sensor boom in an inert plastic shield, thereby eliminating the contamination that caused the dry bias. Starting in May 2001 at the SGP, May 2002 at the TWP, and later 2002 at the NSA, ARM has moved to using RS-90 radiosondes. These sondes are not subject to the contaminatino that caused the dry bias. Vaisala is in the process of developing an algorithm that can be used to estimate the correct RH from knowledge of the sonde age. All of the ARM sounding data have sufficient metadata available to apply the correction. Additionally, ARM has funded a Science Team effort (Milosevich) to develop a 'best' correction algorithm for the RS-80 radiosonde humidity data. When completed this algorithm will allow us to reprocess the accumulated RS-80 data and produce a new data platform with what we hope will be more accurate data.
