Atmospheric angular momentum estimates from MERRA-2, 1994 - 2022

Data supplement for manuscript "Revisiting the excitation of free core nutation" by Mostafa Kiani Shahvandi, Michael Schindelegger, Lara Börger, Siddhartha Mishra and Benedikt Soja, submitted to JGR: Solid Earth. Data source: Modern-Era Retrospective analysis for Research and Applications version 2 (MERRA-2) Temporal resolution: 3 hourly Units for mass and motion terms: kg*m^2*s^(-1) Processing: Stationary signals due to atmospheric tides have been removed Other processing steps: Mass term are corrected for the oceans's IB (inverted barometer) response For further information see ReadMe.txt.
