OverviewAI-generated summary

Gerardo Celis's research investigates carbon cycling in Arctic and boreal ecosystems, with a particular focus on CO2 and methane fluxes. His work examines regional patterns, uncertainties, and decadal changes in carbon uptake and respiratory losses across tundra and permafrost regions. Celis has contributed to the development and analysis of large-scale datasets, including the ABCflux database for Arctic-boreal CO2 flux observations and FLUXNET-CH4 for global methane seasonality in freshwater wetlands.

His publications address the representativeness of eddy covariance site networks and propose strategies for future network enhancements. Celis also explores methods for gap-filling eddy covariance flux data, comparing machine learning models and their associated uncertainties. His research has been instrumental in understanding the long-term carbon balance of northern permafrost ecosystems, indicating persistent carbon emissions despite observed carbon uptake.
