Length of day residuals after the removal of tidal friction, glacial isostatic adjustment, and climatic effects: 720 BC to 2020

LOD residuals after the removal of tidal friction, glacial isostatic adjustment, and climatic effects.
Time range 720 BC to 2020 AD.
Data are with respect to 2020.
First column: time in year (negative years mean BC)
Second column: LOD residuals in milliseconds
Third column: uncertainty of the LOD residuals in milliseconds
