The N2O emissions were estimated by calculating the change in total N2O flux. The total N2O global flux (TgN/yr) was calculated by clubbing the new SPICE core N2O data (Azharuddin et al, 2023) with the existing data from EPICA Dome C (EDC), Dronning Maud Land (EDML) (Flückiger et al., 2002; Schilt et al., 2010), Talos Dome Ice (TALDICE), North Greenland Ice Core Project (NGRIP) (Fischer et al., 2019), Law Dome (Rubino et al., 2019) and Styx and NEEM (Ryu et al., 2020) ice cores using a two-box model. The model assumed the stratosphere and troposphere as individual boxes where the stratospheric N2O destruction and troposphere-stratosphere N2O exchange were well constrained. ...
