Additional Notes:

       twpncdcsurfX1.00 is extracted from the global surface daily summary 
       data provided by the National Climatic Data Center(NCDC).
       Over 8000 stations' data are typically included each month in 
       the daily summary data. twpncdcsurfX1.00 only covers stations for 
       the Tropical Western Pacific (TWP). 
       
       The dataset contains parameters of Daily Temperature, Dewpoint, 
       Sea Level Pressure, Visibility, Windspeed, Max windspeed, Gusts, and   
       precipitation.

       The daily summary data is normally available about 1 month after the 
       the period the data covers and can be retrieved via
       ftp://ftp.ncdc.noaa.gov/pub/data/globalsod/data.txt.Z 
                
       We have files covering 01/96-03/98. Beginning on 05/19/98, we are 
       planning to send out the one year's worth of backlog data per day 
       We will then send the data as received once per month.
