The associated "database.zip" contains "newdt.dbf", a dbaseIII+ format file 
containing half-hourly data derived from the data logger at the Breamlea wind 
generator from 18 August to 24 December 1995. The fields are 
as follows:
    
    chardate  date in character format dd/mm/yyyy
    time      time in character format hh:mm:ss  ALWAYS EASTERN STANDARD
    av_ws     wind run in half hour expressed as average windspeed m/sec
    min_ws    lowest windspeed in the past 30 minutes (5 sec samples)
    max_ws    highest windspeed in the past 30 minutes (5 sec samples)
    dirn      direction of wind (degrees from north) Note that Bass Strait 
              is about 600 metres due SOUTH of this site.
    kwh       kilowatt-hours (multipy by 2 for average power in kW)
    low_mins  minutes in low speed mode (8 pole winding of generator)
    high_mins minutes in high speed mode (6 pole winding of generator)
    switches  generator switching events in past 30 minutes
    datetime  character string YYYYMMDDHHMM of date and time
              note 00:00:00 on 1 October becomes 2400hrs on 30 September
    no_shadow windspeed corrected for the fact that the anemometer is
              "in the shadow" of the wind generator in wind from the 
              north-to-east sector.

DUE TO INCREASING SIZE OF THE DATABASE, IT HAS NOW BEEN SPLIT INTO
SMALLER FRAGMENTS HAVING THE FORMAT "mmmyyDBF.ZIP"   where "mmmyy" is
the month and year of the data set.
