    Erie, Pennsylvania, recorded record snowfall in December 2017, but now those records are nullified.

    Weather experts told NOAA they found serious problems with how snowfall was measured at Erie Airport.

    NOAA agreed with the experts’ recommendations and reinstated older snowfall records set in 1958 and 2010.

They didn't 'nullify it', they validated measurements.  The measurement stations at the airport were over-calculating how much fell, likely due to drift accumulation.

They used data from other stations to validate and improve the findings they had. That's how this kind of stuff works .
