Comments about LIDAR data:
The folders contain daily data files. There are currently two LIDARS at Site 300 (LIDAR-96 and LIDAR-97). Each LIDAR system creates two files per day. One file is the 1 Hz data (.rtd). The other file is the 10 minute average data (.sta)
The datafiles are zipped with a program called 7zip. It can be downloaded here: http://www.7-zip.org/

The file naming structure is: WLS7-XX_YYYY_MM_DD_hh_mm_ss.sta and WLS7-XX_YYYY_MM_DD_hh_mm_ss.rtd, where
  XX = serial number of LIDAR
  YYYY = year
  MM = month
  DD = day
  hh = hour, mm = minute, ss = second (the time is in UTC). the timestamp is relative to the end of the 10-minute averaging period.

These data have not been post-processed in any fashion nor QA-ed in the datafiles. The LIDAR will report NaN if the signal-to-noise ratio is below the set threshold (CNR < -23). This can be due to non-optimal weather conditions (rain, fog), because the air is too clean (the LIDAR relies on aerosols in the atmosphere for backscattering light), or because they instrument is not functioning properly and an internal alarm file is created.

The LIDAR uses 4 beams of pulsed light at a 1.54 um wavelength (near infrared). The light frequency is shifted by the Doppler effect due to the speed of aerosols and the aerosol speed is proportional to the wind speed. Using the 4 radial wind speeds it calculates a 3-D wind vector. Beam 1 = N, Beam 2 = E, Beam 3 = S, Beam 4 = W

Sampling rate is 1 Hz per beam

Wind speed Uncertainty is 0.1-0.2 m/s

Wind direction uncertainty is 1.5 degrees

Samping range is 40-200 m

# of measuring heights is 10

Probe length is 20 m. This means that a measurement at 60 m is actually a volume averaged wind speed from 50-70 m (60 m +/- 10 m). The probed altitude is linearly linked to
the pulse flight delay.

The sampling heights are based from the top of the LIDAR (~40 cm off the ground)

Scanning cone angle is 28 degrees

Output variables in the .sta files include:
  internal temperature (deg C)
  external temperature (deg C) (will be NaN since we don't have a temp/rh probe installed)	
  relative humidity (%) (will be NaN since we don't have a temp/rh probe installed)
  atmospheric pressure (hPa) (will be NaN since we don't have a barametric probe installed)
  wiper count (# of times the windshield wiper was activated during the 10 minute period)
  average horizontal wind speed (m/s)
  average wind speed dispersion (m/s). this is standard deviation of horizontal wind speed
  maximum wind speed (m/s)
  wind direction
  average z wind speed (m/s). this is vertical wind speed
  average z wind speed dispersion (m/s). this is standard deviation of vertical wind speed. 
  CNR (this is average signal to noise ratio during the 10 minute period)
  CNR min (this is minimum signal to noise ratio during the 10 minute period)
  Doppler spectrum broad
  Data availability (%)
  
  
Currently we don't have a temperature/relative humidity probe hooked up to the LIDARs so the data in these columns will be NaN. There is 2 m temp/rh available near the 52 m meteorological tower. Barometric pressure and radiation flux are also available near the met tower(http://www-metdat.llnl.gov/)
