Summary

Description
English: From source: "Ice mass measurement by NASA's GRACE satellites. Gap represents time between missions. Credit: NASA" (includes data from GRACE AND GRACE follow-on)
  • Version 1 was made with Inkscape.
  • Most of the code for Version 4 (2022-01-22) was made with the "line graph" spreadsheet documented at User:RCraig09/Excel to XML for SVG, with subsequent manual edits in text editor to further optimize code.
  • Data for Versions 4 and 9+: Data downloaded from "Get Data HTTP" button at https://climate.nasa.gov/vital-signs/ice-sheets/ (free registration required to download)
  • Data listing for Versions 9+: https://podaac-tools.jpl.nasa.gov/drive/files/allData/tellus/L4/ice_mass/RL06.1/v03/mascon_CRI/antarctica_mass_200204_202211.txt (free registration required to read page)
