Notes：
[1] O₃ represents the maximum daily 8-hour average (MDA8) surface concentration. Annual maps show the mean of available daily MDA8 values. Source: https://doi.org/10.5281/zenodo.10208188.
[2] NO₂ covers 1 January 2003 to 31 August 2024. The 2024 map therefore represents January–August, rather than a complete year.
[3] Temperature data cover 2003–2024. The exact temperature variable and daily aggregation statistic have not been confirmed; the collection is not separated into daily mean, maximum and minimum products.
[4] NDVI covers 1 January 2005 to the composite dated 21 June 2020. The 2020 map uses January–June composites only. Composites dated 21 June, 1 August, 1 September and 1 November 2008 are unavailable.
