[i] *This is the number of DOIs minted by NOAA for datasets created by NOAA and archived at the NOAA Centers for Environmental Information (NCEI). NCEI archives also contain many other datasets for which the information about DOI assignments is not available. Therefore it is not meaningful to compute the percentage for comparison.
