Monthly Fields of Surface Meteorological Variables and Turbulent Fluxes for the Indian Ocean; 1960-1989 These data are monthly, 2-deg mesh, analysis fields of surface variables over the Indian ocean. The technique used to provide these fields is described in a paper Jones et. al.; (1994). There are monthly fields for each month from January 1960 - December 1989. There are 10 analysis variables: (variable name, abbrev, and units of the data) easterly pseudo-stress (u*w) (M/s)**2 northerly pseudo-stress (v*w) (M/s)**2 wind speed (w) M s**-1 sea surface temperature (sst) Degrees-C air temperature (at) Degrees-C sfc humidity (q) kg kg**-1 easterly wind stress (tx) N m**-2 northerly wind stress (ty) N m**-2 sensible heat flux (h) W m**-2 latent heat flux (e) W m**-2 Grid points over land or non-analyzed data locations are indicated by special value (99999.0). The data are available in netCDF format(highly recommended). There is one file (jones_flux.nc) for wind stress and turbulent heat fluxes, and the other file (jones_met.nc) contains the standard meteorological variables. Since netCDF files are fairly well self-describing and transportable across several supported platforms, all support information on reading the data, units, etc are all contained within the files. The two files uncompressed occupy approx 17 Mbytes. Information on netCDF data formatting can be found by contacting the Unidata Program at NCAR/UCAR (see the netCDF_readme file in this directory) The data are also available in ASCII format. The data are organized one variable per file. The names correspond to the above variable names/abbreviations. The size of these files (uncompressed) is approx 4.9 Mbytes each. Thus total would be ~49 Mbytes for the ASCII files. **** notice the savings in disk space using netCDF vs ASCII ! **** The ASCII files in this directory can be read with the following code. integer x(45),y(27) integer month,year c real data(45,27) read(10,'(20i4)') x read(10,'(20i4)') y do 10 i=1,360 read(10,'(i4,2x,i4, 1x, 6e11.4/(7e11.4))')month, year, data ... ... 10 continue x is an array of longitudes which are the centers of the 2-deg. boxes. These are in degrees E. y is an array of latitudes which are the centers of the 2-deg. boxes. These are degrees N, thus negative values indicate Southern Hemisphere. The data values in array location (1,1) are at 31E, 29S. month is an integer month indicator (1-12) year is an integer year indicator (1960-1989) data is a real array(45,27) which contains the analysis field for a single month.
