Ferret Users,
Last week I posted a question seeking a method for having Ferret return the year that a temperature anomaly occurs if given a threshold. The response I received was very helpful and allowed me to do this.
I basically followed these commands:
To your query, it is the way that I use to do.
use data.nc ! load the data !
! generate the mask of the variable (var) in the data set, to your query I hope it is the time series you are talking about e.g. ENSO index time series !
let var1 = if var ge 1 then var !! this is the value which is greater than or equal to 1
let var2 = if var le -1 then var !! this is the value which is less than or equal to -1
list var1, var2 !! this will show you the magnitude with dates !!
save/file=mask-var.nc var1, var2 !! in case if you want to save them !!
exit
***********************************************
Now, I am stuck on the next step. I would like to use the dates generated for the anomolous and non-anomalous years to look at other model outputs. In other words, I want to compare various model outputs during years with and without
temperature anomalies. However, I do not know how to proceed to accomplish this.
Thank you in advance for your help.
