control on these data. 4.0 DATA FORMAT AND FILE NAMING 4.1 Data Format The HPCN dataset contains different parameters depending upon the reporting station. Each station provides Station Name, State, and Identification Number preceding that station's data within the dataset. Each parameter column has a self explanatory title indicating the data available for that station and parameter units. The data are provided "as is" in their original format. Missing values are directly followed by an "M", and estimated parameter values are directly followed by an "E". 4.2 File Naming conventions 397049.121.2002 where: 397049 is the station ID (see station list above). 121 is the start date of the data in that file (Julian days) 2002 is the year 5.0 DATA REMARKS None. 6.0 REFERNCES HPCN Home Page: http://hpccsun.unl.edu/awdn/
