NTN Network NH4 Map and Grid Corrections (2016 – 2017)

The concentration and deposition maps and grids have been updated in the NTN gradient maps page. Starting in November 2024, the original maps, reflecting data generated from an incorrect NH4 mdl value, have been marked as with an “(ERR)” note. The normal links now reflect the updated 2016 and 2017 NH4 values which were corrected in 2023. For details on the original correction, see the original news article.
