File Naming Convention

          xxxxxxxx.pppppp.llctgrr.yymm.sss

where:

          xxxxxxxx   = data product designator (8 chars maximum)
          pppppp     = parameter name (6 chars maximum)
          llctgrr    = code for spatial/temporal resolution & coverage
          yy         = year
          mm         = month number
          sss        = file type designator

A more detailed description follows:

   xxxxxxxx  : tells the user something about where the data came from. This 
               could be either an instrument, a project, or in the case of 
               model output data, an experiment number.
               Examples:  assim54a,  tovsnf (ng is the noaa10 satellite
                          designator)

   pppppp    : parameter name
               examples: temp, sphum, ndvi

   lctgrr    : l = number of levels (1 - 99)

               c = vertical coordinate 
                        p = pressure level, 
                        s = surface,
                        n = not applicable)

               t = temporal period, with the following definitions:

                        m  =   monthly (30 day averages)
                        c  =   climate monthly
                        x  =   climate
                        a  =   annual

               g = horizontal grid resolution, with the following definitions
                   (first number is latitude increment):
            
                        a  =   5 deg lat x 5 deg lon
                        b  =   2.00 deg lat x 2.50 deg lon
                        c  =   1.00 deg lat x 1.25 deg lon

                        n  =   not applicable 
                        p  =   point data
                     
                    others may be added in the future.

               rr = spatial coverage, with the following definitions:
                    
                        gl =   global land  , e.g. avhrr pathfinder
                        go =   global ocean , e.g. ncep sst
                        gg =   global (land & ocean)  e.g. dao, tovs
                        o1 =   ocean region 1 (smmr monsoon) 
 
   yymm      : data of data

               yy = year (e.g. 87=1987)

               mm = month (e.g. 07=july)

   ddd       : file type designator

               bin = binary file (IEEE 32-bit floating point)
                gz = compressed binary file (gzip)
               ctl = GrADS meta-data file
               gif = image file (graphical interchange format)
               asc or ascii = text file (ascii)

Software

Each of the CIDC CD-ROMS contain a software directory. The content of these directories are the following:

aareadme          Readme file which describes the content of the software 
                  directory.
decompression/    Directory that contains decompression software. See the
                  aareadme in the decompression directory for more 
                  information.
grads/            Directory that contains Grid Analysis and Display System
                  software. See the aareadme in the grads directory for more
                  information.
read_cidc_sftwr/  Sample programs in FORTRAN, C and IDL languages to read the
                  CIDC data. Compiled versions for different operating systems
                  have been provided.
xwin/             Directory that contains a demonstration version of the 
                  XWin32 X Server.
