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);
