Urban flow and climate datasets for the United States
15 open urban flow resources for the United States: 12 field measurements, 1 laboratory experiment, 1 simulation dataset and 1 tool or geometry. They cover urban boundary layer, dispersion & air quality and urban heat & thermal comfort. Each entry links to the original repository, with its licence, creators and how to cite it.

High-resolution height map of trees and buildings for Chicago, usable as CFD/LES geometry.
Tools & geometry Geometry
-
5–20 tonne pressurised liquefied chlorine releases in 2015–16, partly inside a staggered array of about 80 shipping containers, with concentration arcs out to 11 km: the key dense-gas benchmark for built environments.
Benchmark Field Measurements
-
Urban Dispersion Program field studies in 2005: two intensive periods around Madison Square Garden (March) and six in Midtown (August) with up to seven perfluorocarbon and SF6 tracers, street-level and rooftop samplers, sonic anemometers and sodars, plus indoor and subway sampling in MID05.
Benchmark Field Measurements
-
DTRA/DHS field study in July 2003: ten 8-hour intensive periods of SF6 releases in the central business district, sampled by 194 bag samplers and 25 fast-response analysers, with winds and turbulence measured at about 100 sites. A classic real-city dispersion benchmark.
Benchmark Field Measurements
-
Classic multiscale urban dispersion campaign: SF6 and perfluorocarbon tracer releases with meteorology around a single building, across the downtown grid and over the wider city, mostly in stable night-time conditions. Files are openly downloadable by IOP.
Benchmark Field Measurements
-
Hamburg wind-tunnel model of the Joint Urban 2003 area of Oklahoma City, used in COST 732; the openly obtainable counterpart to the Joint Urban 2003 field data, whose archive is offline.
Benchmark Lab Measurements Wind tunnel
-
Notebooks, WRF-SLUCM configuration files and processed outputs assessing local warming from data-center heat emissions in California. Useful as a mesoscale urban simulation case setup.

-
Long-running tall-tower eddy-covariance records of momentum, sensible and latent heat and CO2 over downtown and suburban Indianapolis, with raw 10 Hz data for turbulence statistics.
Field Measurements
-
Year-long ARM Mobile Facility deployment with urban, rural and Chesapeake Bay nodes, measuring how the urban boundary layer differs from its surroundings through all seasons, including low-level jets and bay breezes. Doppler lidar, soundings, eddy covariance and profilers; free ARM account needed.
Field Measurements
-
30-minute fluxes of momentum, heat, water vapour and CO2, plus raw 10 Hz sonic data, from a site among highways and buildings at UIC; part of the Chicago CROCUS network, which also runs Doppler lidar and SODAR (open but raw, not quality-controlled).
Field Measurements
-
Continuous Doppler lidar in Baltimore from the BSEC Urban Integrated Field Lab: vertical-velocity variance, skewness and kurtosis, VAD wind profiles, boundary-layer and cloud-base height as daily CF-NetCDF files at 15-minute resolution.
Field Measurements
-
BSEC network of street-level weather stations across Baltimore: temperature, humidity, wind, rain and solar radiation as 5-minute, hourly and daily CSV files from 2023.
Field Measurements
-
A year of ARM Mobile Facility observations around Houston, aimed at sea-breeze convection and aerosol–cloud interaction, with Doppler lidar, soundings, flux and tethered-balloon data on the coastal urban boundary layer. Free ARM account needed.
Field Measurements
-
Eddy-covariance water, energy and carbon fluxes with ancillary meteorology at four urban landscapes in Phoenix during 2015.
Field Measurements
-
17 street-level stations across the five boroughs plus rooftop eddy-covariance and Doppler-lidar / microwave-radiometer profiler sites. The flux readme warns of rooftop flow distortion.
