Extended Data Fig. 1: Data availability between two historical decades.

From: The past and future of global river ice

Extended Data Fig. 1

a, Data availability map for the decades 1984–1994 and 2008–2018 based on the river ice extent dataset. Black indicates no data or no studied river. b, Percentage of successful river ice observations for each month of each decade. The percentage was calculated by taking the ratio between the number of observations used in the historical analysis and the total number of Landsat river observations when no filters (cloud, topographic shadow and river length) were applied.
