Hi James,<br>
Thank you for attention and help again.<br>
I included the line "OPTIONS template", in amazonia.ctl, as you sugest,<br>
show below:<br>
<br>
DSET ^amazonia.clm2.h0.2002-01-%<a href="http://m2-00000.nc" target="_blank">m2-00000.nc</a><br>

The file open perfectily now, see the message below:<br>

But I still could not see the time values ??of four, the following message<br>

Do you know how solve this problem?<br>

Dear Corey,<br>
<br>
There is a problem with how you define the seasonal cycle on your code, specifically line 3. You have:<br>
define nino34clim=ave(nino34,time=jan2020,time=dec2089,12)<br>
<br>
where the averaging should be:<br>
define nino34clim=ave(nino34,t+0,time=dec2089,12)<br>
<br>
Please note the 2nd argument on the average function. It should average through all months, skipping by 12, but should include all times from jan2020 to dec2089.<br>
Hope this helps!!!<br>

***Identical to previous message. Subject line included this time***<br>
<br>
Dear gradsusr mailing list:<br>
<br>
I am attempting to perform a least-squares regression of a 3-month running<br>
mean time series of sea surface temperatures over the Nino 3.4 region over<br>
the 70 year period 2020 to 2089. My goal is to diagnose significant events<br>
over that 70 year period by performing the least-squares regression. I<br>
need to remove the seasonal cycle, and then compare the time series to the<br>
regression line. A couple problems:<br>
1.) GrADS will not allow me to use time as the ind. var. or dep. var. in<br>
the tregr() function or when defining the coeff.(b).<br>
2.) I attempted to invoke climatology, based on the documentation provided<br>
here:<a href="http://grads.wikidot.com/algorithms" target="_blank">http://grads.wikidot.com/algorithms</a>. However, I cannot seem to remove<br>
the seasonality.<br>
<br>
Please find the relevant portion of my code copied below. An alternate<br>
version of my code is also copied below, using a different variable. I<br>
have also attached the anomaly figure that code2(see below) generates.<br>
<br>
Any assistance would be tremendously appreciated!<br>

Dear gradsusr mailing list:<br>
<br>
I am attempting to perform a least-squares regression of a 3-month running<br>
mean time series of sea surface temperatures over the Nino 3.4 region over<br>
the 70 year period 2020 to 2089. My goal is to diagnose significant events<br>
over that 70 year period by performing the least-squares regression. I<br>
need to remove the seasonal cycle, and then compare the time series to the<br>
regression line. A couple problems:<br>
1.) GrADS will not allow me to use time as the ind. var. or dep. var. in<br>
the tregr() function or when defining the coeff.(b).<br>
2.) I attempted to invoke climatology, based on the documentation provided<br>
here:<a href="http://grads.wikidot.com/algorithms" target="_blank">http://grads.wikidot.com/algorithms</a>. However, I cannot seem to remove<br>
the seasonality.<br>
<br>
Please find the relevant portion of my code copied below. An alternate<br>
version of my code is also copied below, using a different variable. I<br>
have also attached the anomaly figure that code2(see below) generates.<br>
<br>
Any assistance would be tremendously appreciated!<br>
