Comment:
These data are made available as a comprehensive archive of WAIS-Divide methane measurements. In the majority of cases the 2-yearly spline fit, available to download from www.usap-dc.org (search for award # 600361), will be the most suitable for your application. The 2 yearly cubic smoothing spline fills gaps in the data set and reduces data set size, whilst also reducing noise (that could be noise due to the wider analytical system e.g., pressure fluctuations, or archival noise).
