  Coronal Mass Ejections (CMEs) contributes to the perturbation of solar wind
in the heliosphere. Thus, depending on the different phases of the solar cycle
and the rate of CME occurrence, contribution of CMEs to solar wind parameters
near the Earth changes. In the present study, we examine the long term
occurrence rate of CMEs, their speeds, angular widths and masses. We attempt to
find correlation between near sun parameters, determined using white light
images from coronagraphs, with solar wind measurements near the Earth from
in-situ instruments. Importantly, we attempt to find what fraction of the
averaged solar wind mass near the Earth is provided by the CMEs during
different phases of the solar cycles.
