Answer 1

Try this,

snowDepth_full = zeros(365,3); % make a temporary variable to hold everything
snowDepth_full(1:121,:)  = snowDepth(1:121,:);   % First 121 days up to april 30
snowDepth_full(end-90,:) = snowDepth(122:end,:); % Last 91 days from oct 1 on
snowDepth = snowDepth_full;  % Copy it back 

Then as before...

snowdepth2009 = snowdepth(:,1);
snowdepth2010 = snowdepth(:,2);
snowdepth2011 = snowdepth(:,3);
...
