[gradsusr] Serious Lterp Issue With GFS Data & Climatology Data

[Perry, Aaron @ LSC]

Good Evening Everyone,

Currently, I'm having an issue with lterping two variables, one being 850mb temp with a recent GFS .ctl file and a climatological 850mb temp .ctl. The recent GFS .ctl is fine and the climate .ctl is coarse. I have been trying to read up on lterp as much as possible but, I can't seem to get this work and I've reached the end of possible resources it seems like...

The script in question is below:

ctl1 = '~/grads/data/cfsrclim/t850.cfsr.mean.clim.daily.1982.2010.ctl'
ctl2 = '~/grads/data/gfs.t12z.pgrbf33.ctl'

'open 'ctl1''
'set x 1 360'
'open 'ctl2''

'set dfile 1'
'define t850clim = (TMP850mb-273.15)*(9/5)+32)'

'set dfile 2'
'define t850curr = (tmpprs(lev=850)-273.15)*(9/5)+32)'

'define t850a = (t850clim(t="00Z01jan1984"))'

'define t850b = (t850curr(t="18Z15jan2014"))'

'define final = lterp(t850b,t850a)'

'define hi = t850a-final'

'd hi'


Onward and Upward,
