I have temperature data with dimensions [288 192 60] or [lat lon time]. I would like to calculated the weighted average temperature with area data [288 192] to get a time series of weighted average temperature [1 60]. Does anyone know a good way to do this in matlab?

hello

my 2 cents suggestion

 data = rand(288,192,60); % dummy data
 
 [m,n,p] = size(data);
 dataw = zeros(1,p);
 
 for ci = 1:p
     tmp = data(:,:,ci);
     dataw(ci) =  mean(tmp,'all'); % 2D spatial linear average of the temperature
 end
 
 plot(dataw);
