Hi, From a netcdf file I have extracted my variables of interest which have these dimensions: aa_lon 609x881 aa_lat 609x881 bsfd 609x881x372 time 1x372 My first goal is to extract bsfd values inside this area gsg = (aa_lon>=-12 & aa_lon =73 & aa_lat<=78); and calculate the mean over the entire time period in order to have a matrix of two dimensions which I can plot as a spatial map: Secondly I wuold like to have yearly mean of the same variable to produce the same type of maps but for every year. THANK YOU VERY MUCH!

Hi,

From a netcdf file I have extracted my variables of interest which have these dimensions:

aa_lon 609x881

aa_lat 609x881

bsfd 609x881x372

time 1x372

My first goal is to extract bsfd values inside this area

gsg = (aa_lon>=-12 & aa_lon<=9 & aa_lat>=73 & aa_lat<=78);

and calculate the mean over the entire time period in order to have a matrix of two dimensions which I can plot as a spatial map:

Secondly I wuold like to have yearly mean of the same variable to produce the same type of maps but for every year.

THANK YOU VERY MUCH!

SOLVED!!

prova = mean(bsfd,3); % this calculate the mean value over the entire time period

prova_yr = (bsfd(:,:,1:12:372)); % this is to calculate yearly mean and have a spatial representation
