Baltimore Turfgrass Field Experiment

1 December 2024 - 31 December 2025

Lead Scientist: Ben Ahlswede

Observatory: AMF (ARM Mobile Facility 1)

We would like to characterize the energetic and trace gas fluxes from turfgrass in Baltimore. This campaign will improve our understanding of urban vegetation fluxes and their role in atmospheric proceses from urban landscapes. Turfgrass is the dominatnt vegetation type in Baltimore and other urban areas, but are largely ignored in weather and earth system models.

We will erect a small eddy covariance system to measure the fluxes of carbon, water, and energy from the turfgrass field at AMF1. The flux tower will measure fluxes from the surface approximately 10 meters away from the tower. Data are collected continuously at 10 Hz and are averaged up to 30 minute intervals. These are direct measurments of energy and trace gas fluxes, and can be directly compared to model outputs.
