Subject: [netcdfgroup] I wonder why I can not wirte NC files by
usingnc_put_vara_float
first i used NC_CREATE to create an nc file,then i used NC_WRITE to modify the
contents. After that i found i can change the status except the contents by
using nc_put_vara_float. source:
<nabble_embed>
void CreateAMonthFile(char *OutputPath,float* val,struct ParameterGroup pg){
...
size_t startp[] ={ RealTimeNumber, 0, 0, 0 };
size_t countp[] ={ 1, 1, pg.LatNumber, pg.LonNumber };
iForecastTime = 0;
for (; iForecastTime < pg.ForecastNumber; iForecastTime++){
float ValTemp[115 * 87];
i = 0;
for (; i < pg.LatNumber * pg.LonNumber; i++){
ValTemp[i] = val[INDEX(iForecastTime, iVar, i, pg.VarNumber, pg.LatNumber
* pg.LonNumber)];
}
status = nc_put_vara_float(ncid, varid[iForecastTime], startp, countp,
ValTemp);
if (status != NC_NOERR) handle_error(status);
}
...
}
it seems correct. but when i using
void AddNewFile(char *OutputPath,float* val,struct ParameterGroup pg, int
RealTimeNumber){
...
nc_open(path, NC_WRITE, &ncid);
if (status != NC_NOERR) handle_error(status);
...
size_t startp[] ={ RealTimeNumber, 0, 0, 0 };
size_t countp[] ={ 1, 1, pg.LatNumber, pg.LonNumber };
float ValTemp[pg.LonNumber * pg.LatNumber];
int i = 0;
for (; i < pg.LatNumber * pg.LonNumber; i++) {
ValTemp[i] = val[INDEX(iForecastTime, iVar, i, pg.VarNumber, pg.LatNumber *
pg.LonNumber)];
i++;
}
char s[3];
sprintf(s, "%03d", iForecastTime);
memcpy(Varname, VarNameString[iVar], 10);
strcat(Varname, s);
status = nc_inq_varid(ncid, Varname, &varid[iForecastTime]);
if (status != NC_NOERR) handle_error(status);
status = nc_put_vara_float(ncid, varid[iForecastTime], startp, countp,
ValTemp);
if (status != NC_NOERR) handle_error(status);
...
}
in this section i found it is no changes whatever the values of ValTemp i
filled
