%
%  Merges data from two consecutive months, if the rissaga happens to occur
%  on the last day of a month (year).
%
%  Input arguments:
%     struct1: first month data structure from readBarometerObs
%     strcut2: second month data structure from readBarometerObs
%
%
% Output:
%   outstruct: concatenated data from both months, cropped to a given
%   timewindow (2 days usualy).
