Coastal forested wetlands in the southeastern US provide important ecosystem services, including the conservation of biodiversity, supplying clean, abundant water resources, and the cycling and storage of carbon, which feeds… More
Cities have a complex mix of land uses, from commercial districts with dining and shops to residential neighborhoods linked by travel corridors, as well as industrial areas such as ports and factories. All of these different land uses lead to a diversity of urban sources that emit volatile organic compounds (VOCs) and greenhouse gasses such as carbon dioxide (CO2) and methane (CH4). Direct measurements and analysis of these species over time helps us understand human interactions with climate and air pollution.
I have a love-hate relationship with winter. As manager of the Niwot Ridge US-NR1 AmeriFlux site (Blanken et al., 1998-present), located in a subalpine forest on the east side of… More
The AmeriFlux FLUXNET data product generated by the AmeriFlux Management Project (AMP) is now available to download for 21 sites (and counting) via Download Data. The AmeriFlux FLUXNET data… More
Carbon dynamics and greenhouse fluxes in a Florida native rangeland. The Science: Grazing lands, including both rangeland and pastureland, cover about 10.7 Mha in Southeastern United States; have a significant… More
The ‘amerifluxr’ [pronounced: uh-merr-ee-fluhks-arrr] — an R package that allows querying, downloading, and handling AmeriFlux data and metadata — is now released through the CRAN repository. The package was developed… More

The encroachment of woody species such as mangrove invading coastal marshes is expected to change the carbon storage in the soils and biomass as well as exchanges with the atmosphere.
We all know the importance of soil as a CO2 source to the atmosphere, even in high latitude/altitude ecosystems with persistent snow cover. Before the days of automated soil respiration… More
