Century5 and DayCent5 Site Parameters: Spatial netCDF File

Site parameters can be stored in either a netCDF file, or a text-format site.100 file. A spatial netCDF file contains a collection of sites, in which each site is identified by latitude, longitude and ID number. This netCDF file can be produced when you use the CopySoil, CopySite, and other utilties that create site files.

This spatial netCDF file uses the netCDF version 4 data types, and variables are compressed. The format of the file is:

netcdf sites {

    dimensions:
        record = UNLIMITED ; // (0 currently)
        count = 323 ;        // varies according to DayCent5 or Century5

    variables:
        float lat(record) ;
            lat:long_name = "latitude of center of cell" ;
