  In[[ late 2023 it was discovered>>https://epic.earthscope.org/content/smartsolo-archives-flipped-polarity-igu-16hr-3c-5hz]] that the vertical Z channel of **the IGU-16HR short period **SmartSolo nodes is actually inverted relative to the standard expectation of "positive up" (vertical axis dip = -90). EarthScope's solution was to add a -1 multiplier to the //response data.// Because we have a much smaller volume of this data to fix, and far less of it already distributed prior to this announcement, we have opted to do the opposite; e.g. we invert the //raw data// because the data is what is wrong; not the response.
--**In late 2025 we also discovered that the horizontal (N and E) channels are ALSO flipped! Data downloaded before Friday 5 December 2025 is affected- multiply your DH[NE] channels by -1 if you have already downloaded them.**

  Until very recently we also thought that the BD3C-5 "broadband" nodes had inverted data by default, but now understand that their raw exported data has the correct polarity.
