[gradsusr] ENSO Forecast Plumes

I am still unable to plot the data using your script. I have modified the script so that it only grabs the CFSv2 and CMC1 data, I am still getting the same error message. I added say dfile to make sure the dfile showed the correct url, which it did.

http://monsoondata.org:9090/dods/nmme/201505/tmpsfc_CFSv2
syntax error, unexpected WORD_STRING, expecting WORD_WORD
context: Error { code = 0; message = "subset requests must include a constraint expression"^;};
sdfdeflev: nc_get_vara_double failed to read coordinate axis values
 NetCDF: Malformed or inaccessible DAP DATADDS
gadsdf: Failed to define X coordinate values.
SET Error:  No files open yet
SET Error:  No files open yet
SET Error:  No files open yet
SET Error:  No files open yet
SET Error:  No files open yet
DEFINE error:  no file open yet

I further investigated the script and added say URL to this portion of your script to see what came up.

*   build a server-side analysis URL
    dset='nmme/'year%mm'/tmpsfc_'model.m
    expr='eloop(tloop(aave(tmpsfc,lon=-170,lon=-120,lat=-5,lat=5)))' ;* NINO3.4 definition
    dims='0:0,-90:-90,0:0,'time1':'time2',01:'numens.m
    URL=server'_expr_{'dset'}{'expr'}{'dims'}'
    say URL

The script returned the same error as shown above, but now I have this URL result from the say URL command, which is:

http://monsoondata.org:9090/dods/_expr_{nmme/201605/tmpsfc_CMC1}{eloop(tloop(aave(tmpsfc,lon=-170,lon=-120,lat=-5,lat=5)))}{0:0,-90:-90,0:0,00Z01MAY2016:00Z01DEC2016,01:10}

I tried to sdfopen on this URL without the script since it was the next part of the script:

*   This may take some time if the calculation result is not cached
    'sdfopen 'URL

When I did sdfopen http://monsoondata.org:9090/dods/_expr_{nmme/201605/tmpsfc_CMC1}{eloop(tloop(aave(tmpsfc,lon=-170,lon=-120,lat=-5,lat=5)))}{0:0,-90:-90,0:0,00Z01MAY2016:00Z01DEC2016,01:10} on the command line without the script. The error I got was: 

syntax error, unexpected WORD_STRING, expecting WORD_WORD
context: Error { code = 0; message = "subset requests must include a constraint expression"^;};
sdfdeflev: nc_get_vara_double failed to read coordinate axis values
 NetCDF: Malformed or inaccessible DAP DATADDS
gadsdf: Failed to define X coordinate values.

Which is the same error I get when I run the script. So this leads me to believe that the opening error of the file is coming from the 'building server-side URL' portion of the script. Does the URL that was outputted from the say URL command seem right to you?

The models included in the NMME have changed over the years, the list in the script is complete but many of them will be absent for any one forecast. Error messages like this one are harmless, it only means that a forecast initialized 2016-05 for CFSv1 does
 not exist. The script should include whatever models are available for the desired initalization date.

Hello Jennifer,

Excellent job with this plot! I am kind of getting road blocked. I am getting this error when I run the script:

syntax error, unexpected WORD_STRING, expecting WORD_WORD

context: Error { code = 0; message = "/nmme/201605/tmpsfc_CFSv1 is not an available dataset"^;};

Error: nc_open failed to open file 
http://monsoondata.org:9090/dods/nmme/201605/tmpsfc_CFSv1

NetCDF: Malformed or inaccessible DAP DDS

gadsdf: Couldn't ingest SDF metadata.

syntax error, unexpected WORD_STRING, expecting WORD_WORD

context: Error { code = 0; message = "subset requests must include a constraint expression"^;};

sdfdeflev: nc_get_vara_double failed to read coordinate axis values

Do you have any idea what may be causing the problem? I tried to sdfopen the links by themselves without the script the links work fine (well the ones that are available on the GDS server in the NMME directory).

Thanks,

James

Dear All,
I created a graphic that depicts ensemble forecast plumes with embedded histograms at each lead time. The plots convey information about the variability in the ensemble in a clear and easy-to-interpret format. The initial application uses forecasts of
 NINO3.4 index from the NMME data archive. The web site given below explains the graphic, presents an archive of images, and provides a link to the script, which accesses the data from COLA’s GDS, so you can try it without having to download any data. There’s
 a companion web page with an animation of plumes spanning the recent El Nino event — look for the link at the end of the explantory text.
