As of 1 May 2018 the centralized payment of article processing charges (APCs) with the Leibniz Association has been extended to 53 Leibniz Institutions participating in the Leibniz Association's Open Access Publishing Fund.

Authors from the Potsdam Institute for Climate Impact Research (PIK) will profit from a new institutional agreement with Copernicus Publications starting 23 August 2017. The agreement which is valid for the first author enables a direct settlement of article processing charges (APCs) between the PIK and the publisher.

The updated publication policy now is extended by the journal's open access statement, its archiving and indexing scheme, and explicit policies on corrections and retractions.
