North-South topographic asymmetry index which is the base-10 logarithm of the ratio of the median slope of the north-facing to that of the south-facing pixels within a 25 km by 25 km cell. The data set consists of 5 file pairs, each pair comprising the index itself and its bootstrap-derived standard error estimate (se suffix) bandpass_logratio: N-S logratio asymmetry index using the baseline configuration (0.04 slope threshold, bandpass filter) bandpass_logratioEW: E-W logratio asymmetry index using the baseline configuration bandpass002_logratio: N-S index using a slope threshold of 0.02 bandpass008_logratio: N-S index using a slope threshold of 0.08 lowpass_logratio: N-S index without high-pass filtering The data were derived from the ArcticDEM: Porter, Claire; Morin, Paul; Howat, Ian; Noh, Myoung-Jon; Bates, Brian; Peterman, Kenneth; Keesey, Scott; Schlenk, Matthew; Gardiner, Judith; Tomko, Karen; Willis, Michael; Kelleher, Cole; Cloutier, Michael; Husby, Eric; Foga, Steven; Nakamura, Hitomi; Platson, Melisa; Wethington, Michael, Jr.; Williamson, Cathleen; Bauer, Gregory; Enos, Jeremy; Arnold, Galen; Kramer, William; Becker, Peter; Doshi, Abhijit; D’Souza, Cristelle; Cummens, Pat; Laurier, Fabien; Bojesen, Mikkel, 2018, “ArcticDEM”, https://doi.org/10.7910/DVN/OHHUKH, Harvard Dataverse, V1 The data are associated with Zwieback, S.
