If you are using wordpress you can add the meta tags in:
(1) manually in your archives files. I would only recommend this option if you are familiar with php and wordpress.
(2) use a plugin -- most likely can't mention it here but you can google "wordpress seo". There are several plugins that can help with this. With the plugin all you have to do is go to 'titles and meta' section, and click 'Noindex subpages of archives' button.
