GRIB_GETDATA

The GRIB_GETDATA function returns the key/value pairs associated with a requested record in the form of an ORDEREDHASH.

Examples

In this example, we locate a GRIB file and ask IDL to return the 2nd record.

file = FILEPATH('atl.grb2',SUBDIRECTORY=['examples','data'])

data = GRIB_GETDATA(file, 2)

IDL returns:

help, data

DATA            ORDEREDHASH  <ID=1  NELEMENTS=224>

Result = GRIB_GETDATA( filename, record)

Returns an ORDEREDHASH of the requested record. The ORDEREDHASH contains all of the keys present in the record.

A string denoting the name of the GRIB file for which IDL will return a record.

The number of the record in the GRIB file IDL will return.
