Hi all :)
I would like to know how to compute the area enclosed by a contour line plotted using contourm.
I have a 361x361 matrix respectivly for LAT, LON, sicstart. (sicEASE is also 361x361)
sicstart is basicly matrix containing 0, 1 or NaN.
I wanted to use polyarea(x,y) but I am not sure how to use it since I have a matrix of 0 ,1 or NaN and no (x,y) coordinates...
I have attached a figure of the contours I want to compute the area. Here is the code for the blue contour.
sicstart = sicEASE;
index1 = find(sicEASE >= 0.15);
index2 = find(sicEASE < 0.15);
sicstart(index1) = 1;
sicstart(index2) = 0;
ncpolarm('lat',66); hold on;
Thanks for your help
