Pulse-Reserve behaviour of the soil-plant continuum refers to the increased water uptake by plants following precipitation/soil moisture pulses and exists across biomes. Despite its prevalence, the influence of these pulses on the net carbon uptake of plants from the atmosphere is not well explored. Utilizing data from 160 sites of FLUXNET 2015 dataset and 2 sites from ISRO's National Carbon Project - Soil, Vegetation and Atmospheric Fluxes (NCP-SVAF) project across the globe, we analyse the changes in Net Ecosystem Productivity (NEP) during dry downs following soil moisture pulses. Our analysis indicates a consistent increase in NEP after soil moisture pulses in both dryland (annual rainfall <500 mm) and mesic (annual rainfall >500 mm) ecosystems. The NEP increase persists longer in dryland ecosystems than in mesic ecosystems, with the latter reaching a stable NEP value more rapidly. Post-pulse changes in NEP for dryland ecosystems exhibit greater sensitivity to pulse magnitude (PM) and pre-pulse soil moisture levels than those observed in the mesic ecosystem. The post-pulse increases in NEP in both ecosystems are impacted by temperature and Vapor Pressure Deficit (VPD); mesic ecosystems are more sensitive to these meteorological factors. Our findings on post-pulse NEP characteristics will contribute to enhancing vegetation parameterization schemes in earth system modelling, facilitating a deeper understanding of the coupling between the carbon and water cycles.
