The 2023 Ameriflux Urban Fluxes workshop was held November 13-14 at Argonne National Laboratory.
AmeriFlux, hosted by Lawrence Berkeley National Laboratory, is a network of sites measuring ecosystem CO2, water, and energy fluxes in North, Central and South America. It was established to connect research on field sites representing major climate and ecological biomes, including tundra, grasslands, savanna, crops, and conifer, deciduous, and tropical forests.
Urban settings, though, are a complex environment to study and a difficult one at that. But having information on fluxes in an urban setting, such as the interaction between the earth’s surface and atmosphere, is critical.
One way to help fill in research gaps is with U.S. Department of Energy Urban Integrated Field Laboratories like Community Research on Climate & Urban Science (CROCUS). Ultimately, the invited workshop participants, including CROCUS scientists, will develop a white paper on the current state of urban fluxes and approaches on how to fill in the gaps.
EVS researchers involved in the Urban Fluxes Workshop included Paytsar Muradyan, atmospheric scientist and CROCUS measurement deputy; Scott Collis, CROCUS measurement lead and Argonne Testbed for Multiscale Observational Science (ATMOS) director; Adam Theisen, ATMOS development lead; Sujan Pal, hydroclimatologist; and Roser Matamala, senior terrestrial ecologist.
“The Urban Fluxes workshop was a fantastic opportunity for us to collaborate with people who have been doing flux measurements for a long time,” said Muradyan. “They have experiences that we can learn from and in turn, we communicated plans we have for CROCUS and showcased Argonne’s capabilities.”
One of those capabilities is ATMOS, which features a flux tower onsite. Workshop attendees had the chance to tour the ATMOS site and see what future opportunities for collaborations were available.
“We want to be able to position ourselves to others that we have the power, the people, the flux tower,” said Muradyan. “Bring your project to ATMOS and test it here.”
