Fig. 2: Recent increase in Antarctic precipitation.

a Daily precipitation based on ERA5 over the AIS throughout the year, where the green line represents the example year from Jul 2021 to Jun 2022. Blue shading indicates the daily standard deviation over the full 2003–2024 period. Red and orange line represent the mean daily precipitation (10-day rolling mean) during 2003–2019 and 2020–2024, respectively. The difference of these two lines (red minus orange) is shown in (b), where red and blue coloured sections mark days where the difference is larger than the standard deviation of the difference (approximately 1 Gt day−1), which is represented by the yellow dotted lines. 124 (22) days are significantly higher (lower) during 2020–2024 compared to 2003–2019.
