2. What geographic area does the data set cover?

   West_Bounding_Coordinate: -80.64

   East_Bounding_Coordinate: -80.52

   North_Bounding_Coordinate: 25.64

   South_Bounding_Coordinate: 25.35

3. What does it look like?

4. Does the data set describe conditions during a particular time period?

   Beginning_Date: 01-Jun-1997

   Ending_Date: 31-Dec-1997

   Currentness_Reference: ground condition

5. What is the general form of this data set?

   Geospatial_Data_Presentation_Form: text files

6. How does the data set represent geographic features?
   1. How are geographic features stored in the data set?

   2. What coordinate system is used to represent geographic features?

      Horizontal positions are specified in geographic coordinates, that is, latitude and longitude. Latitudes are given to the nearest 1. Longitudes are given to the nearest 1. Latitude and longitude values are specified in Degrees, minutes, and decimal seconds.

      The horizontal datum used is North American Datum of 1983.
      The ellipsoid used is Geodetic Reference System 80.
      The semi-major axis of the ellipsoid used is 6378137.
      The flattening of the ellipsoid used is 1/298.257.
      

7. How does the data set describe geographic features?

   Entity_and_Attribute_Overview:

   The data are in columns in the following order: year, month, day, hour (military convention, 0-23 ), minute, second (always 0 for this data), speed in meters/second, direction in degrees. Direction reported in the files is direction FROM which the wind is blowing. O is a wind from the North, 90 is wind from the East, 180 is wind from the South, and 270 is wind from the West.

Why was the data set created?

With insight into the functional relationships and into the scales at which wind forcing data must be collected for model input gained from the field efforts, the treatment of wind forcing in models can be improved. This, in turn, can lead to enhanced understanding of the significance of wind effects on flow, transport, and horizontal mixing in the SICS (Southern inland coastal systems of Miami-Dade County) study area.

How was the data set created?

1. From what previous works were the data drawn?

2. How were the data generated, processed, and modified?

   Date: 1999 (process 1 of 1)

   These data were collected originally by Ed German of the USGS. Gaps in the original data have been filled by linear interpolation of the wind speed and wind direction. For data collected between September, 1995 and January, 1998, less than .2 percent of the data have been interpolated. In addition, the vast majority of the interpolations are over single missing data points.
