SGP/SONDE/C1 - Incorrect surface temperature
DataStreams:sgpsondewrpnC1.a0, sgpsondewrpnC1.a1
Description:
It appears as if the operator mis-typed the temperature when entering the
surface values into the system.  The value appears as 89.0 degC instead of
8.9 degC.  Also note that there are no RH data in this sounding other than
the initial value of 100%.  The reason for this loss of RH is unknown.

SGP/SONDE - Questionable absolute pressures
DataStreams:sgpsondewrpnC1.00, sgpsondewrpnC1.a0, sgpsondewrpnC1.a1
Description:
The sonde surface pressure reading was considerably higher than the
corresponding THWAPS pressure (988.0 hPa vs 982.3 hPa).  The sonde
readings are consistent during the sounding, however, suggesting that
this is not a case of a pressure jump at launch but one of sensor offset.
This problem will only affect those who use the absolute pressure values.
The file altitudes, which are based on the relative pressure changes
from the surface, should be fine.

sgpsondewrpnC1.a1, sgpsondewndcalcC1.c1
Description:
It appears as if the operators had a problem with the original sounding
and launched a second radiosonde.  Apparently they used the calibration
tape that came with the first radiosonde (serial number 943156405) in
place of the one that was correct for the second radiosonde (sn 943156406)
and all the data are bad after the first sample (surface values).

SGP/SONDE/C1 - Incorrect absolute pressure
DataStreams:sgpsondewrpnC1.00, sgpsondewrpnC1.a0, sgpsondewrpnC1.a1, sgpsondewndcalcC1.c1
Description:
The surface pressure (983.5 hPa) reported by this radiosonde (sn 94315713)
is substantially higher than that reported by the THWAPS (~977) or by the
sondes used in the previous and following soundings (976.6, 977.3).  This
may be a calibration problem or a mechanic problem on launch.  The pressure
values reported in the remainder of the sounding are consistent with the
reported surface pressure, so the altitudes should be correct.  The
absolute pressure values may be high by about 5 hPa.

Description:
The value for air temperature at the surface in this file is 23.3 degC.  This value is too 
high and resulted from incorrect data entry (typographic mistake) by the operator.  The 
true value as determined from the operator pre-launch logs is 12.3 degC.

SGP/MWR/C1 - Intermittent Negative Sky Brightness Temperatures
DataStreams:sgpmwrlosC1.a1, sgpmwrlosC1.b1, sgp1mwravgC1.c1, sgp5mwravgC1.c1
Description:
Several related and recurring problems with the SGP MWRs have been
reported dating back to 1999.  These problems were due to the
occurrence of blackbody signals (in counts) that were half of those
expected. The symptoms included noisy data (especially at Purcell),
spikes in the data (especially at Vici), negative brightness
temperatures, and apparent loss of serial communication between the
computer and the radiometer, which results in a self-termination of the
MWR program (especially at the CF).

Because these all initially appeared to be hardware-related problems,
the instrument mentor and SGP site operations personnel (1) repeatedly
cleaned and replaced the fiber optic comm. components, (2) swapped
radiometers, (3) sent radiometers back to Radiometrics for evaluation
(which has not revealed any instrument problems), and (4) reconfigured
the computer's operating system.  Despite several attempts to isolate
and correct it, the problem persisted.

It became apparent that some component of the Windows98 configuration
conflicted with the DOS-based MWR program or affected the serial port
or the contents of the serial port buffer. This problem was finally
corrected by upgrading the MWR software with a new Windows-compatible
program.

Description:
Radiosondes manufactured at Vaisala's Woburn, MA factory during the first
of January 1998 have incorrect serial numbers.  Instead of being numbered
8012XXXXX these sondes are numbered 7012XXXXX.  Vaisala has been informed
of this, has confirmed the problem, and has corrected their numbering for
all subsequent sondes.  163 incorrectly numbered sondes were shipped to ARM
on 1/9/98.  Some have been used at the CF since 1/19/98:1430.

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.
