<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>
<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>
inc = 1<br>
<br>
'set gxout fwrite'<br>
'set fwrite 'path1''path2'hgt500.1985.2014.mean.grib'<br>
<br>
while(count<=rec)<br>
<br>
'set t 't<br>
<br>
say t<br>
<br>
'set lon -320 40' <br>
'set lat -30 90'<br>
<br>
'define hgt500 = (hgt500mb.1/100)'<br>
<br>
'define climo=ave(hgt500,t=0,t='t',1mo)'<br>
<br>
'd climo'<br>
<br>
count = count + incr<br>
t = t + incr<br>
fhr = fhr + inc<br>
<br>
endwhile<br>
<br>
'quit'<br>
<br>
