[gradsusr] ENSO Forecast Plumes Script

[Jennifer M Adams]

Hi, James —
The data I use to draw the plumes is freely available from NOAA:

ftp://ftp.cpc.ncep.noaa.gov/wd52dg/data/indices/sstoi.indices  (for the obs)
ftp://ftp.cpc.ncep.noaa.gov/NMME/realtime_anom (for the model forecasts)

You will need to download the data and create your own descriptor files, but that is a very straightforward task — no special tricks. Recently the format of the model data changed -- now it is NetCDF instead of GRIB — which makes it even easier. Below is the bit of script code for writing the ascii data as a binary time series:

'set gxout fwrite'
t=0
while (1)
  res=read(ascfile)
  line1=sublin(res,1)
  line2=sublin(res,2)
  rc1 = subwrd(line1,1)
  if (rc1); break; endif
  ck=subwrd(line2,1)
  if (ck!='YR')
    t=t+1
    year=ck
    m=subwrd(line2,2)
    val=subwrd(line2,10)
    'd 'val
    if (t=1)
      iyear=year
      imon=subwrd(mons,m)
    endif
  endif
endwhile
'disable fwrite'

Hi all,

I was wondering if there was an updated link for the ENSO Forecast Plumes script since the URL http://monsoondata.org:9090/dods/ has been decommissioned.

The script is hosted here http://cola.gmu.edu/enso_forecast_plumes.html and looks to still be running just fine, but the script does not contain an updated link. If there is a replacement link, can some please provide the new link.

Thank you,
James
