Thread-topic: [ferret_users] vertical weighted averagng

Dears,
sorry if I was not clear enough with my question.
I have model outputs which are not equally spaced in vertical and I'd like to know how to calculate for instance weighted mean in vertical temperature. As example I attached a file with results from single point,
Thanks in advance,

Hi,

I don't know exactly about the question you are asking but i think its very simple to do.

suppose you are having var(i,j,k,l)

so its simply you can do to average about a single point also suppose you are having k=1:27, 1 corresponds to surface and you want to make average of your 5th level only then you have to do like this

let lev5_ave=var[k=5@ave]

this way you can do to average out the level and it works also.

I hope this is the thing you were asking.

regards, saurabh

Ferreters,
I know that @AVE transformation computes the length-weight average of point in horizontal, but how to calculate weighted average for one point but in vertical?
Thanks in advance,
