Data Set Overview
    =================
      Near surface winds were studied at two sites on Lunar Lake
      Playa:
 
      (a) Lunar Lake North is at the northeast end of the
          playa, on a smooth clay-silt surface; and
 
      (b) Lunar Lake South is toward the center of the playa,
          just east of the area of prominent basalt gravel bars
          on the playa.
 
      In addition to providing data on surface winds to GRSFE, these
      investigations will provide input to studies of the
      relationships between the radar backscatter and aeolian
      roughness characteristics of desert surfaces.
 
      Data were recorded at Lunar Lake North between 13:32 on 16 July
      1989 and 17:16 on 18 July 1989 for a total of 52 hours; and at
      Lunar Lake South between 16:51 on 16 July 1989 and 16:13 on 18
      July 1989 for a total of 48 hours.  During these periods, wind
      speeds recorded at a height of 9.6 m varied between 1.36 and
      8.16 m/sec.  The 20 minute averages of wind speed recorded do
      not reflect the very unsteady and gusty wind conditions that
      were observed during GRSFE.  Wind directions during periods of
      winds above 4 m/sec were mostly from south to southeast.  Wind
      data are presented in degrees clockwise from magnetic north.
      Temperatures at a height of 1.5 m above the surface ranged from
      a minimum of 9.25 degrees C around 05:00 on 17 July, to a
      maximum of 35.62 degrees C on the afternoon of 18 July.
 
      The wind experiment data set is divided into two files, one for
      each wind tower.  The data are in tabular form.

Overview
    ========
      A recording interval of 20 minutes was adopted, so all data
      represent a 20 minute average of wind speed and temperature
      conditions.  A malfunction in the analog to digital converter
      resulted in no temperature or wind direction data being
      recorded at Lunar Lake South.
