Review and update of critical limits within the framework of critical load modeling for acidifying and eutrophying nitrogen
Duration: 2021 - 2023
Objective: Check the general need for updating the SMB CL modeling. Results will be used to keep the CL methodology up to date together with the NFCs of the ICP Modeling and Mapping.
Steady-State Critical Loads for eutrophication and acidification for European terrestrial ecosystems
Duration: November 2019 – February 2021
Objective: The project aimed to improve the European background database used by the Coordination Centre for Effects (CCE) to calculate Critical Loads (CLs) for eutrophication and acidification for (semi-) natural European terrestrial ecosystems. The database is used when member countries do not provide their own CL data to the CCE. In this case, the missing country data are replaced by the results of the background database when the CCE produces European CL maps. This report describes the (a) underlying datasets; (b) derivation of the input data for the CL model; (c) R packages and scripts developed; and (c) verification of the results. These results feed into international and national policy advice, e.g., they are an important input to the Gothenburg Protocol Review currently underway in the year 2021.
Objective: In this project a literature review on empirical Critical Loads will be conducted. This serves as preliminary study for the subsequent update of the empirical Critical Loads.

R-Project
Duration: August – November 2019
Objective: The internal workflow of the CCE regarding the calculation of Critical Loads and their exceedance with the statistic program R will be supported.
