Re: [ferret_users] Calculting model agreement



Hello Saurabh, Hello Ferreters

Thanks for the script and guidelines.

However, I want to know, how I can compare these models (8 in my case), say, precipitation to observation data (chirps), what would be the approach?

Because here, my guess is I'll be comparing that to the observation mean. And how to do that is my frustration.

Regards
Kwesi

Dear Kwesi
G'day

I tried to use previous suggestion given by Russ, Ryo and other on my data. SO my data consists of 11 CMIP5 models and I want to show atleast 7 or 8 models agreement in sign. So I did it in this way. Slope is my linear trend from 11 cmip5 models. But before applying this method I combined all my slope from all the different models into a single netcdf file (attached jnl script). So that I can do the computation in my desired dimension which is 'm' here. Here 'm' represents the total number of models or ensembles. 

I hope this will help. 


let tsign = if slope ge 0 then 1 else (-1)
let agree80 = if abs(tsign[m=1:11@sum]) ge 8 then 1

fill agree80*slope[m=@ave]

Hello Ferreters

I am trying to make a plot with model agreement. 

I want to plot model agreement over some observation. Hence, how the models agree to the sign of change. 

Attached is a snippet of my script. I would kindly want to know  if I am doing it right and if not, the best way to approach it.

Thanks for your help in advance.
