ENMI Europe Dataset

Data Description (v1)

This datasets consist of ENMI (Environmental Nitrogen Management Index (ENMI)) estimaets for Europen countries, EU‑27 member states and NUTS‑1 regions. It pairs with R scripts so external users can reproduce the country/EU‑27/regional ENMI metrics, tables, and figures referenced in the study. 

Excel sheets

enmi_country_yearly/decade.xlsx: yearly and decadal ENMI values at country-level with metadata README tabs.

enmi_eu27_yearly/decade.xlsx: yearly and decadal ENMI values at EU27-level with metadata README tabs.

enmi_nuts1_yearly/decade.xlsx: yearly and decadal ENMI values at NUTS1-levelwith metadata README tabs.

Rscripts

01_compute_n_surplus_ratios.R: critical N surplus aggregation and country ratios.

02_compute_n_output_ratios.R: reference nitrogen output levels and actual/output ratios.

03_compute_enmi.R: ENMI calculation

04_export_enmi_tables.R: Excel workbooks (country, EU‑27, NUTS‑1) with README sheets.

05_plot_enmi_timeseries.R: Rscript for ENMI timeseries plot provided as an example (Figure 1b)

Unit & Resolution

ENMI is a unitless index bounded in [0, 1]; 

Time period: 1961-2019
