Extended Data Fig. 6: NASA’s ATM flight lines.
From: Extensive inland thinning and speed-up of Northeast Greenland Ice Stream

NASA’s ATM surveys in northeast Greenland during spring 2011 (a), spring 2012 (b), spring 2013 (c), spring 2014 (d), spring 2015 (e), spring 2016 (f), spring 2017 (g), spring 2018 (h) and spring 2019 (i). Black lines denote flight lines. Elevation changes in m year−1 from NASA’s ATM surveys in 2016 and 2017 (j). Negative values indicate surface lowering. The image was prepared using MATLAB R2021a software.
