SGP/RL - Raman lidar out of alignment

The Raman lidar was returned to service after a laser repair on 2/10/2000.
During normal instrument startup, the system attempts to optimize the 
alignment of the outgoing laser beam in the detector's field-of-view.
Occassionally, this routine fails to do this successfully, but subsequent
alignment "tweaks" (which typically occur every three hours) will usually
readjust the system and thus any periods of data related to poor alignment
are kept short.  However, shortly after system startup on the 10th, low
clouds moved in overhead which prevented the system from re-optimizing
itself.  To make matters worse, the system slowly drifted further out
of alignment, and thus when the sky conditions improved the system was
unable to correct its misalignment.  Site operations performed a restart
on Monday morning (2/14 around 1430 UT) which returned the lidar to its
nominal alignment.  Data from this period, especially the narrow field-of-
view data, will be greatly affected by this misalignment and probably 
should not be used.

SGP/SONDE/C1 - Incorrect surface temperature

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

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.

SGP/SONDE/C1 - Operator used wrong calibration tape

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

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.

SGP/SONDE/C1 - Incorrect surface temperature

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/RL/C1 - Ground bin channel variability introduced height offsets

A maintenence visit in January 1999 to work on the Raman lidar laser
resulted in a height offset being introduced into the raw data.  This
offset was found and corrected, but approximately six weeks of data (of 
which the lidar was only operational for about 14 days) have the ground
bin at #69 versus #65 (a 156 m offset).

A second, related but more serious, problem that resulted in height offsets was
due to different styles of multi-channel scalar (MCS) cards in the system.  The first 
(original) style was used in the system had the ground at bin #66.  However,
these cards occasionally faulted and 5 of them were replaced simultaneously
at the end of the 1997 Water Vapor IOP.  The new style of cards have slightly different 
electronics, which resulted in the ground bin being at bin #65 rather
than #66.  Since there were still 2 of the old style cards in the system
when it was restarted (they had not yet faulted), the result is that there are channel 
dependent height offsets for a period of time, until finally new style 
MCS cards were put in all channels.  

Since most of the derived products from the Raman lidar are ratios of two channels, this 
difference in the ground bin has a undesired and somewhat disguised effect on the data.

The mentor has decreed that ground bin #65 shall be the standard for all raman
lidar data.  The data affected by the ground bin variability are in the queue for 
reprocessing to remove the offset.  In the interim, these data should be used with caution.

Incorrect radiosonde serial numbers

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.

SGP/SONDE - Dry bias in sonde RH

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.

SGP/SONDE - Wrong cal tape

There is something wrong with this sounding, its not clear exactly
what happened, however.  The first values reported by the radiosonde
are much different from those entered by the operator.  My impression
is that this is a calibration tape mixup.  The raw data file shows
that the sounding software was initialized twice for this sounding,
the first time showing sonde 823360910, the second time showing
sonde 819351814.  There is no enties in the operations log that
describe a problem with a sonde before launch.

SGP/SONDE - Pressure jump at launch

The difference between the sonde-reported pressure at the surface
(969.1 hPa) and the first pressure value reported after launch
(963.5) is larger than expected.  This may indicate that either
the pressure sensor was jarred at launch, that the system failed
to correctly identify the launch start time, or some other problem.

The ascent rates during the first 30 seconds of the sounding will be
incorrect as will the absolute altitudes during the sounding.

SGP/SONDE - RH probably biased low in several soundings

In the process of moving storage facilties, site operations uncovered some old radiosondes 
(vintage April 1998) that were used in several soundings starting on May 10 at 0530 and 
continuing at least through May 11 at 2040.
Because these sondes are so old and pre-date Vaisala's repackaging they are likely subject 
to the sensor contamination problem that results in a dry bias in RH.  The sondes in 
question have serial numbers 816XXXXXX.

SGP/SONDE - Incorrect surface temperature

The operator entered the surface temperature as 25 degC rather than the
correct 2.5 deg C.  This is the second time in a week this type of error
has occurred.  I have sent a separate e-mail to site ops.
