WVSS-II Validation Louisville (WVL)
UW-CIMSS AERIBago
      -----------------------

      Date: 17 June 2005 CST (Friday) 0000 - 1200 UTC
      Location: Kentucky Air National Guard at SDF Airport
      Operators: M. Richards and T. Wagner

     Weather Conditions:

Cool and pleasant.  Temperatures in the low 60s, dewpoints in the low
50s.  Sky had a few light cirrus early in the night, clearing for the
remainder of the night.

      Instrument Status:

*  AERIBago - Units working normally
*  Surface station - working and archiving
*  Ceilometer - working and archiving
*  GPS system - GPS unit is archiving properly.
*  AERI - archiving properly.  The computer monitor for the AERI
computer was located, so the operators are now able to keep an eye on
systems.
*  Radiosonde system is working and archiving

3 launches were completed today
0240 UTC  Launch normal, data good, sounding manually terminated
0645 UTC  Launch normal, data good, sounding manually terminated
0930 UTC  Launch delayed to 0930 UTC at ATC request.  Launch normal.

Science Discussion:
Again looks like WVSS-II thermodynamic boundary layer comparisons agreeing quite well with UW-CIMSS radiosonde data.

Figure 1:  FSL Tail number 287 and 701 compared to 0645 UTC radiosonde

Figure 2:  FSL tail  number 285 and 701 both ascending at 0923 UTC and radiosonde launched at 0930 UTC
