DATA_SET_TERSE_DESCRIPTION
DATA_SET_DESCRIPTION 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.
