TAMDAR AERI-bago Validation Experiment (TAVE) Daily Summary
-----------------------

Date: 25 February 2005 CST (Thursday) 0000-2400 UTC
Location: Memphis Air National Guard at MEM Airport
Operators: W. Feltz, E. Olson, K. Bedka, T. Wagner

Weather Conditions:

High in the mid-50's, clear, light winds, nice day

Instrument Status:

*  Surface sensors (temperature, relative humidity, pressure and winds) working and archiving
*  Ceilometer working but still fixing a dating problem
*  AERI working and archiving
*  Radiosonde system is working much better -  The day has been much smoother with regard to radiosonde launches.  Most of the routine involves avoiding Vaisala software hiccups.
Radiosonde Summary:
	0200 Radiosonde Launch - Good launch, however Vaisala editted
sonde ascii data was none existant, raw data does exist so we will be able
to recover the profile
	1430 Radiosonde Launch - Successful launch, however only Vaisala
binary file is available due to premature Vaisala sonde termination, ascii
EDT file (used by Bill Moninger) was not useful, profile will be
	recovered through post processing
       1615 Radiosonde Launch - Great sonde launch and data set
       2015 Radiosonde Launch - Great sonde launch and data set
       2300 Radiosonde Launch - Great sonde launch and data set
	After several iterations we now have a stable launch procedure
that seems to provide the best chance for success, we should have a high
rate of successful launches from this day forward (fingers crossed). 
* GPS system has been deployed and is collecting data 
* AERIBago had a power surge at ~0030 UTC and bago-vespa and bago-aeri
rebooted, all other systems worked fine, no fuse issues, seemed to be
related to plugging in spot light to outside (rear right) plug.  This was
also the same power strip that portable heater was plugged into, tape was
applied to plug cover so this would not be attempted again.  All
conditions nominal the rest of day.

Also I would like to give a big thanks to Lt Adkins and his group who have done a wonderful job of hosting us on base.  The site is nicely taped off and there responses to our needs have been tremendous.

Science: 
Comparisons between MEM TAMDAR and RUC20 data revealed that RUC20
portrayed a stonger but lower (~800 mb (TAMDAR) vs ~875 mb (RUC20)
subsidence inversion during the afternoon.  Otherwise, profiles have
agreed quite well in today's data and in days past.

First comparison (attached) between TAMDAR and sonde via Bill Moninger's
FSL Java web site attached below.  More comparison will be coming.

Miscellaneous:
Tim Wagner arrived today and Wayne Feltz has left.
