It was recently discovered that the NTN network Data Export utility was not including certain sites in it’s downloads. We have corrected this error on October 22nd, 2025. All unrestricted sites should now be included the NTN Data Export reports. This did not occur for the MDN or AMON networks.
The cause of this issue stemmed from a newer site code, and is no older than 2023. If you downloaded weekly, monthly, seasonal, annual, or water year reports from the NTN Data Export utility in the last two years, please check the list of sites against this master list to determine if you are missing site data. Re-downloading the data should now include all allowed sites for the specified period.
Sites that may be affected are:
AR02, AZ97, AZ99, CA42, CA45, CAN5, CO06, CO09, CO15, FL05, GA09, KS32, KS97, ME08, MI48, MN28, MT00, NY10, NY59, NY93, PA13, SC03, SC05, TN14, VA00, WY02, WY06, WY99
