GRIB_PUTDATA
This procedure adds a new record to an existing GRIB file. If the file does not exists, IDL will create a file in the specified location.
Examples
In this example, we locate a GRIB file on disk, create a copy in the current directory
file = FILEPATH('atl.grb2', $
SUBDIRECTORY=['examples','data'])
FILE_COPY,file,'atl.grb2'
GRIB_LIST,'atl.grb2'
IDL displays:
|
1 |
crain |
DOUBLEARRAY[141151] |
|
2 |
usct |
DOUBLEARRAY[141151] |
|
3 |
vsct |
DOUBLEARRAY[141151] |
|
4 |
tsec |
DOUBLEARRAY[141151] |
Now we create a GRIB record and add it to the file:
record = ORDEREDHASH()
record['values'] = dblarr(1024)
GRIB_PUTDATA, file, record
Now we check to see if the record has been added:
GRIB_LIST, file
IDL displays:
|
1 |
crain |
DOUBLEARRAY[141151] |
|
2 |
usct |
DOUBLEARRAY[141151] |
|
3 |
vsct |
DOUBLEARRAY[141151] |
|
4 |
tsec |
DOUBLEARRAY[141151] |
|
5 |
t |
DOUBLEARRAY[1024] |
Syntax
GRIB_PUTDATA, filename, record
Arguments
FILENAME
A string denoting the name of the GRIB file for which IDL will append to/create.
RECORD
An ORDEREDHASH of the record IDL will add to the file. IDL does not check the validity of the record. The user is expected to know which keys they can insert into the record. If a new file is being created, the record is expected to have the GRIBEditionNumber key specifying the type of GRIB file.
Note: GRIBEditionNumber can have a value of 1 or 2, signifying GRIB edition 1 or GRIB edition 2 respectively.
