## How to make two different grid systems comparable?

Hello all,

I am trying to solve a problem which has been solved previously, but I am still struglling to figure a way out. I want to unify the coordinate systems (polar stereographic coordinate) in the Arctic from two different dataset – a) NSIDC sea ice motion nand b) ECCO sea ice motion.

Now, the NSIDC one has a grid system of 361×361 but the ECCO has a 90×90 grid system. I am tryiong to make a point by poiny velocity comparison in these two dataset and this why I want to prepare a unified coordinate system first so that NSIDC also becomes 90×90 (or any other way to make them comparable).

This is the velocity profile from both data set on 11-Jan-2017.

I have attached the velocity field from both dataset in this question (NSIDC_vs_ECCO.mat. This is the code for the plot –

for day = 1:31

figure(1), clf; clc;

t = tiledlayout(1,2); t.TileSpacing = ‘tight’; t.Padding = ‘compact’;

% NSIDC

nexttile

pcolor(longitude,latitude,seaice_NSIDC(:,:,day));

shading interp; hold on;

title(‘NSIDC Polar Pathfinder’,’FontSize’,F);

% ECCO

nexttile

pcolor(X,Y,seaice_ECCO(:,:,day)); colorbar; clim([0 0.55]);

shading interp; hold on;

title(‘ECCO sea ice velocity’,’FontSize’,F);

sgtitle([datestr(NSIDC_datetime(day), ‘yyyy-mm-dd’)],’FontSize’,F+5);

end

Can anyone please help me out with making a code that with calcuate the difference betwen the velocity vectors in both dataset?

As in, "NSIDC – ECCO" plot

Any feedback will be highly appreciated!! Thank you so much for your time.Hello all,
