Extended Data Fig. 5: Changes in the climatological precipitation and the fingerprint pattern of the ridge regression method.
From: Anthropogenic fingerprints in daily precipitation revealed by deep learning

a,b, The observed difference of the climatological precipitation during 2016–2020 from that during 1980–1984 in MSWEP (a) and CESM2 LE (b) (unit: mm day−1). c, The fingerprint pattern of the ridge regression model obtained by calculating the regression coefficients of the daily precipitation anomalies with respect to the AGMT during 1850–2100 in CESM2 LE (unit: °C mm−1 day−1). The map was generated using the Basemap Toolkit (version 1.2.0; https://matplotlib.org/basemap/).
