Time series data collected from 3 towers during Cases99 experiment.
     Tower 7 (800m NE of 60m tower)
     Tower 8 (800m NW of 60m tower)
     Gully Tower (2 heights of flux measurements) Located in the northern end of Gully

Each Tower (7 and 8) was equiped with a Campbell Scientific KH20 and a Campbell Scientific
3-D Sonic.  Data was collected at 20 Hz.  

Site 7 the system was orientated to 123 deg  (east) at a height of 5m.  The 3D SN141, the KH20
SN1006 (-xkw mult.  -.157)

Site 8 the system was orientated to 95 deg  (east) at a height of 5m.    The 3D SN184, the KH20
SN1221 (-xkw mult.  -.196)

Gully bottom the system was orientated to 123 deg (east) at a height of  1.5m.    The 3D SN143,
the KH20 SN1238 (-xkw mult.  -.175)

Gully top the system was orientated to 121 deg (east) at a height of  5m.    The 3D SN172, the
KH20 SN1222 (-xkw mult.  -.194)

The file naming convention is as follows:
	GTSaDOYHR.out		Gully Time Series, top(a), DOY data collected, Hour of data collection(CST) .
	GTSbDOYHR.out		Gully Time Series, bottom(b), DOY data collected, Hour of data collection(CST).
	TS7_DOYHR.out		Tower 7 Time Series, DOY data collected, Hour of data collection(CST). 
	TS8_DOYHR.out		Tower 8 Time Series, DOY data collected, Hour of data collection(CST). 

All times are CST.

The data set has been corrected for the SDM offset with the 23X logger input pipeline.

The data format is as follows:

DOY  Hour Sec  Ux   Uy   Uz   c    Diag 	Temp     KH20

JD   CST   s   m/s  m/s  m/s  m/s  count     	deg. C    mV

     c = (speed of sound - 340 m/s)

dataset.
