Fig. 2: Overview of the carbon impact of the European droughts of 2022 and 2018.
From: Temperature extremes of 2022 reduced carbon uptake by forests in Europe
a The different regions struck by the droughts (See Methods) of 2018 ("North” in blue), 2022 ("South” in yellow, “East” in red), or both years ("Centre” in blue/yellow hatched). Note that the East region is far away from the centre of the 2022 geopotential height anomaly 1. b Fire fluxes, taken from GFAS61 over the South (yellow) and North (blue) regions. c–f Net Ecosystem Exchange (NEE) anomalies (negative means less uptake) per region relative to 2016–2021 (excluding 2018) for MAM (clear), JJA (vertical hatching), and SON (crossed hatching), as calculated by the biosphere model SiB4 (see Methods). g–j Monthly mean MODIS NIRv signal (see Methods) per region for drought years, compared with the climatology between 2016 and 2021 (excluding 2018) (in grey). Colours in (c–j) refer to the regions of the same colour in panel a, where (d, h) correspond to the central region, with yellow and blue and representing 2022 and 2018, respectively.
