% to find a datafile: search in basedir/subdir, first try filename with string
% substitution, otherwise list all and try to match regexp.

% to list all granules: listdir basedir/subdir, match regexp, limit to
% matching period

% variables: YEAR, YEAR02, MONTH, DAY, DOY, SAT, SAT1, SAT2
% regexp-output: year, doy, day, hour, minute , end. (end if the file ending)
