Effects of Extreme Temperature and Precipitation Events on Daily CO2 Fluxes in the Tropics

Climate, Journal Year: 2023, Volume and Issue: 11(6), P. 117 - 117

The effects of anomalous weather conditions (such as extreme temperatures and precipitation) on CO2 flux variability in different tropical ecosystems were assessed using available reanalysis data, well information about daily net fluxes from the global FLUXNET database. A working hypothesis study suggests that response vegetation can differ depending local geographical intensity temperature precipitation anomalies. results highlighted large diversity responses to fluctuations may significantly some previously documented relationships (e.g., higher emission under drier hotter weather, uptake colder wetter conditions). They showed heavy mainly leads strong intensification mean release into atmosphere at almost all stations types biomes. For majority considered ecosystems, during cold wet was found, whereas predominantly served sinks hot/dry conditions. Such disparate suggested positive negative anomalies influence Gross Primary Production (GPP) Ecosystem Respiration (ER) rates differently result various Net Exchanges (NEE) external impacts. Their also depend biotic abiotic factors, including plant canopy age structure, biodiversity plasticity, soil organic carbon water availability, surface topography, solar radiation fluctuation, etc.

Rain use efficiency gradients across Australian ecosystems

Rain use efficiency (RUE) quantifies the ecosystem's capacity to precipitation water assimilate atmospheric CO2. The spatial distribution of RUE and its drivers across Australian continent is largely unknown. This knowledge gap limits our understanding possible contribution ecosystems global carbon assimilation. study investigates diverse terrestrial in Australia. results show that ranges from 0.43 (1st percentile) 3.10 (99th g C m−2 mm−1 with a continental mean 1.19 mm−1.
