An Eddy Covariance Mesonet For Measuring Greenhouse Gas Fluxes in Coastal South Carolina

摘要

Coastal ecosystems are vulnerable to climate change and have been identified as sourcesof uncertainty in the global carbon budget. Here we introduce a recently established mesonet ofeddy covariance towers in South Carolina and describe the sensor arrays and data workflow usedto produce three site-years of flux observations in coastal ecosystems. The tower sites representtidal salt marsh (US-HB1), mature longleaf pine forest (US-HB2), and longleaf pine restoration(replanted clearcut; US-HB3). Coastal ecosystems remain less represented in climate studies despitetheir potential to sequester large amounts of carbon. Our goal in publishing this open access datasetis to contribute observations in understudied coastal ecosystems to facilitate synthesis and modelinganalyses that advance carbon cycle science.
