The dataset is provided by the Australian Ocean Data Network and was last updated in June 2026.
British Columbia's Ministry of Environment provides verified hourly air pollutant and meteorological data from monitoring stations across the province. The dataset includes quality-assured readings for pollutants like PM2.5, ozone, and nitrogen dioxide from 1980 to 2024, and meteorological parameters like temperature and wind from 1980 to 2022. All data are reported in Pacific Standard Time.
WNA-FLEXPART-BackTraj-2015 is a 2015 Western North America Back Trajectory dataset produced by NASA using the FLEXPART dispersion model.

A 195.3 KB document assesses the integration of climate justice into the climate strategies of four Dutch cities participating in the EU Mission on Climate-neutral and Smart Cities. The study, authored by Joëlle Tillij and last updated in May 2026, developed and applied a Climate Justice Integration Index to the cities' strategies and conducted stakeholder interviews. It found the cities scored higher on procedural and distributional justice than on recognition justice.
