[gradsusr] Monthly Clim. and least Squares_2020-2089 time series (montly data)

Dear Corey,
Your code has a minor mistake, This is how I would remove the seasonal cycle:
set t 1 840
define nino34=(aave((sst-273.15),lon=120,lon=170,lat=-5,lat=5))
set t 1 12
define nino34clim=ave(nino34,t+0,t=840,12)
modify nino34clim seasonal
set t 1 840
d nino34 - nino34clim
Note, there is a minor difference in how you and I defined the second argument from the average function. You need to loop through all times, that is the reason why you need the second argument as t+0 instead of t=1.
Hope this help!!!

Hosmay and James:
Thank you so much for taking the time out of your day to answer my question.
Dear All: As per Jim and Hosmay's instructions, I invoked the following code to produce climatology in the attached figure. Their instructions correspond with the documentation provided here: http://grads.wikidot.com/algorithms. There are still two problems:
1.) I thought that the code copied below would remove the seasonal cycle from my anomaly map. It still looks like the anomaly is centered around an annual average, rather than making a comparison between Jan clim. and Jan actual sst, February, March and so on. here is the code:
**Bolded portion produces the attached figure.
set t 1 840
define nino34=(aave((sst-273.15),lon=120,lon=170,lat=-5,lat=5))
set t 1 12
define nino34clim=ave(nino34,t=1,t=840,12)
modify nino34clim seasonal
set t 1 840
d nino34 - nino34clim
***This is the attempt to perform the least-squares regression.
c
set cstyle 3
set ccolor 1
set cmark 0
define cff=tregr(nino34,nino34clim,t=1,t=840)
define linearnino34clim=cff*nino34+nino34clim
d nino34-linearnino34clim
2.) After successfully creating the anomaly from climatology, what I'd like to do is draw a regression line throughout the time series, and then compare the actual sst to the best fit for each month in the time series. The departure from the trend will signal ENSO events and allow me to look deeper into the system.
Again, any help would be greatly appreciated!

Hi James,
Thank you for attention and help again.
I included the line "OPTIONS template", in amazonia.ctl, as you sugest,
show below:
DSET ^amazonia.clm2.h0.2002-01-%m2-00000.nc<http://m2-00000.nc>
OPTIONS template
OPTIONS 365_day_calendar
tdef time 4 linear 01jan2002 1dy
The file open perfectily now, see the message below:
ga-> xdfopen amazonia.ctl

SDF file amazonia.clm2.h0.2002-01-%m2-00000.nc<http://m2-00000.nc> is open as file 1

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

Do you know how solve this problem?

Dear Corey,
There is a problem with how you define the seasonal cycle on your code, specifically line 3. You have:
define nino34clim=ave(nino34,time=jan2020,time=dec2089,12)
where the averaging should be:
define nino34clim=ave(nino34,t+0,time=dec2089,12)
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.
Hope this helps!!!

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