Abstract : At the Kodaikanal (KKL) observatory we have four sets of data consists of While light photoheliograms since 1904, the Ca-K line spectroheliograms since 1906, Hα spectroheliograms since 1912 to 1998 and K-pr prominences spectroheliograms since 1912 to 1998. All these data are observed with same instruments with no change in their optics throughout the 100 years. Thus these uniform and contiguous images of 100 years are extremely valuable to study the long term variations of the Sun over a century. We have recently digitized al these dataset and made it open to the global community through the portal https://kso.iiap.res.in. In this talk I will present a summary of recent science results from this digitized archive
