[gradsusr] CTL forecast in CMC1 model

Mon Oct 31 15:24:22 EDT 2016

Dear Jeff

This is my descriptor.

dset ^CMC1.r4
title NMME Monthly Hindcasts; CMC1-CanCM3 Sea Surface Temperature
Initialized 00Z01JAN2012
dtype r4
undef 9.999e+20
xdef 360 linear 0 1.0
ydef 61 linear -30.0 1.0
zdef 1 linear 0 1
tdef 12 linear 00Z01JAN2015 1mo
edef 10 names 1 2 3 4 5 6 7 8 9 10
vars 1
sst 0 1,e,t,y,x Sea Surface Temperature [C]
endvars

Thanks a lot!
