This dataset contains the data supporting the manuscript Lambert et al., Adaptation time to magnified flood hazards underestimated when derived from tide gauge records, submitted to Environmental Research Letters. All files contain two main variables: AF is the amplification factor as a function of [station, time, scenario] DT is the doubling time as a function of [station, scenario] Note that these files contain data of all 299 available stations, rather than the subset of 130 presented in the manuscript.
