We have developed a simple and systematic method (no observer needed) to identify fluctuations that could be related to Interplanetary Coronal Mass Ejections (ICMEs). We estimated the fluctuations of different parameters of the ICMEs as velocity, magnetic field, temperature and density measured in situ at one astronomical unit. We used data from WIND and ACE space crafts from January 1997 to April 2011. A structure of interest was defined where at least three of four of the parameter fluctuations exceeded 3.6 the standard deviation magnitude. In this work we present the highlighted results of our previous analysis and we focus in the cross correlation of the parameter fluctuations. By using the cross correlation we are ensuring that the fluctuations are related temporally with each other and it is more accurate to say that these fluctuations are due to an ICME.
