Monthly Fields of Surface Meteorological Variables and Turbulent Fluxes
		   for the Indian Ocean; 1960-1993


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.; (1995). There are
monthly fields for each month from January 1960 - December 1983. 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 (ndn6093f.nc) for wind stress and turbulent heat fluxes,
and the other file (ndn6093m.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 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
	...
	...

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.

Information on netCDF data formatting can be found by contacting the
Unidata Program at NCAR/UCAR (see the netCDF_readme file in this
directory), e.g. http://www.unidata.ucar.edu/packages/netcdf/index.html

Available in this directory are FORTRAN programs to read the netCDF
files (these still require the netCDF libraries!).
