SGP/SONDE/C1 - Bad temp (other?) data in 12/3/01:2328 sounding

It looks as though the temperature sensor was damaged on launch.  The
recorded temp goes from 16.4 at the surface to -42.6 at 2 seconds into the
flight.  The temperature never exceeds -42 though the RH and pressure look
reasonable, but probably should be considered questionable.

SGP/SONDE/C1 - Bad temperature in CF sounding 12/22/01:0527

The temperature data in this sounding look bad after the first value.  The
temperature series is 11.4, 2.6, -14.3, -32.4 in the first 6 seconds of
flight.  I don't know why this occurred, but it obviously is incorrect.
The pressure and RH data look reasonable.

SGP/SONDE/C1 - Bad temperature data CF sounding 12/28/01:2326

The temperature data in this sounding are bad from approximately 16 seconds
into the flight.  The temperature series is 9.9, 10.8, 11.3, 1.5, 11.6, 11.6,
11.6, -32.2 and remains below -30 degC.  I don't know why this occurred, but
it clearly is incorrect.  The pressure data looks OK as does the RH, though
the RH data are missing (probably sensor failure) above roughly 3.5 km.

SGP/AERI/C1 - Time Offset Corrected

The SGP.C1 AERI system clock was not being regularly checked and synched
with a time server between May 2001 and November 2001.  When the problem
was identified and the clock was corrected, a time offset of 17 minutes
and 2 seconds (slow) was present.

The data available from the ARM Archive have been time corrected
by Dave Turner using a piece-wise linear function based on a comparison
of pressure data from the AERI and SMOS. Dave indicates "this results
in a good fit to the data" and "errors in the reported sample times are
reduced to approximately 1 minute or less.  Given the nominal three minute
averaging period of the AERI, this should suffice for most applications."

Data between 20011019.1615-20011029.1621 did not need to be corrected
due to a series of events that caused the clock to be temporarily
synched and then revert back to the linear drift pattern.

Note, there are three other variables in the AERI data products which
report time: Time, timeHHMMSS and rawTimeHHMMSS.  The data in these
variables were not modified, so these data will not agree with basetime
+ time_offset.

Also note, VAPs which use the AERI data as input were NOT reprocessed.
VAP data during the time period specified are questionable and should
be used with caution.

SGP/RL/C1 - Decreased sensitivity

The sensitivity of the Raman Lidar degraded significantly beginning in late 2001.  Between 
May and September 2004, the electronics were upgraded and the telescope was refurbished 
resulting in sensitivity better than when the instrument system was first installed.

A detailed technical report describing the effects of the signal degradation and the steps 
taken to correct the problem is being written.  In the interim, contact Dave Turner 
(dave.turner@pnl.gov) for more information.

SGP/SONDE/C1 - Increased precision for alt, dp, pres, rh, tdry

The output precision of the following variables was increased 20060928

alt  changed from 1m to 0.1m
dp   changed from 0.1degC to 0.01degC
pres changed from 0.1 hPa to 0.01 hPa
RH   changed from 1%RH to 0.01%RH
tdry changed from .1degC to 0.01degC

Note that the increase in precision does not necessarily imply an increase in accuracy.  
Users are cautioned to continue to use their best scientific judgement when using these or 
any other data.

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.
