<p>Hi Wesley,</p>
<p><br>
</p>
<p>I have tried and implemented this method and have not been able to generate the correct (any actually) climatology to generate the anomalies. I've attached my working script to this email for you to review if you have a spare second to perhaps be able to
see what I'm doing wrong.</p>
<p><br>
</p>
<p>Talk soon,<br>

<p>Good Afternoon Users,</p>
<p><br>
</p>
<p>I have a grib1 file that contains 500mb heights from 1985 to 2014, using the NCEP/NCAR Reanalysis Dataset. I am trying to create an averaged climatology file to create monthly anomalies with. I've written a small GrADS script to try and create this climo
file but, I'm not having much luck with it. The script outputs a .grib1 file but, no control file, as advertised.</p>
<p><br>
</p>
<p>What am I doing wrong?</p>
<p><br>

<p>Script Code:</p>
<p><br>
</p>
<p>function pull (args)<br>
<br>
'reinit'<br>
<br>
rc = gsfallow('on')<br>
<br>
currdate = subwrd(args,1)<br>
curr_run = subwrd(args,2)<br>
regions = subwrd(args,3)<br>
month = subwrd(args,4)<br>
date = sublin(currdate,1)<br>
mon = substr(date,5,2)<br>
day = substr(date,7,2)<br>
yr = substr(date,1,4)<br>
<br>
path1 = '/mnt/homes/perrya/'<br>
path2 = 'new.climate.atlas/'<br>
model = ncep_reanal<br>
<br>
var = hgt500<br>
<br>
'open 'path1''path2'hgt500.mon.1985.2014.grib.ctl'<br>
<br>
count = 0<br>
rec = 360<br>
incr = 1; t = 0<br>
fhr = 0<br>

<br>
