Dear all,
I am doing a fortran code to read and perform some specific meteorological
calculations with my netcdf files. I am a new user in this fortran
environment and I don't know how to use the ncdump information to read my
netcdf data files.
Do you have any ideas how should I proceed?
Is there any special issues to take in account when we are reading netcdf
files with Fortran?
My ncdump information is:
***
netcdf susana.q.1000.7808 {
dimensions:
rlon = 110 ;
rlat = 104 ;
height = 1 ;
time = 52 ;
time_bnds = 2 ;
variables:
char rotated_pole ;
rotated_pole:grid_mapping_name = "rotated_latitude_longitude" ;
rotated_pole:grid_north_pole_latitude = 37.f ;
rotated_pole:grid_north_pole_longitude = -153.f ;
float lon(rlat, rlon) ;
lon:standard_name = "longitude" ;
lon:long_name = "longitude" ;
lon:units = "degrees_east" ;
float lat(rlat, rlon) ;
lat:standard_name = "latitude" ;
lat:long_name = "latitude" ;
lat:units = "degrees_north" ;
float rlon(rlon) ;
rlon:axis = "X" ;
rlon:standard_name = "rotated_longitude" ;
rlon:long_name = "rotated longitude" ;
rlon:units = "degrees" ;
float rlat(rlat) ;
rlat:axis = "Y" ;
rlat:standard_name = "rotated_latitude" ;
rlat:long_name = "rotated latitude" ;
rlat:units = "degrees" ;
float height(height) ;
height:axis = "Z" ;
height:standard_name = "altitude" ;
height:long_name = "altitude" ;
height:units = "m" ;
height:positive = "up" ;
float time(time) ;
time:axis = "T" ;
time:calendar = "360_day" ;
time:long_name = "Julian Day" ;
time:bounds = "time_bnds" ;
time:units = "days since 1961-01-01 00:00:00.0" ;
float time_bnds(time, time_bnds) ;
float q(time, height, rlat, rlon) ;
q:units = "1" ;
q:standard_name = "specific_humidity" ;
q:long_name = "Specific Humidity" ;
q:cell_methods = "time: mean" ;
q:coordinates = "lon lat" ;
// global attributes:
:Conventions = "CF1.0" ;
:source = "HIRHAM" ;
:experiment = "HC1" ;
:institution = "DMI" ;
}
*****
Many thanks in advance.
Susana.

you should have a look at the fortran documentation for accessing netcdf
data files:
http://www.unidata.ucar.edu/packages/netcdf/f90/Documentation/f90-html-docs/
and/or
http://www.unidata.ucar.edu/packages/netcdf/guidef/
it's really not that tricky, actually i do prefer using netcdf i/o to
normal fortran i/o.
cheers
