Horizontal and vertical wind speed and temperature were collected at 10-Hz.The data is from a series of experiments using liquid pool fires and small-scale laboratory work to characterize the way structure and heterogeneity of fuel elements change the drag and convective heat transfer in plume dynamics. Other datasets were collected and complement this dataset as part of the Department of Defense project RC20-1362. All related datasets titles start with "A multiscale study of the coupling between flow, fire and vegetation static field experiments:".The TT field experiments were conducted using multiple liquid pool fire (pan) configurations on a clearing where all vegetation was removed. Nine sonic anemometers were mounted on towers downwind from the pans in three arrays at 6, 10 and 30-ft (1.8, 3 and 9.1-m) heights. A control sonic was located 14.6-m upwind of the center pan on a 5-ft (1.5-m) tower.The SRS field experiments were conducted using multiple pan configurations within a 2-ha loblolly and long leaf pine plantation. Understory vegetation was removed in all burns and tree density reduced in some burns. Nineteen sonic anemometers were mounted on 11 towers around the pan configurations at heights 6, 10, 25 and 40-ft (1.8, 3, 7.6 and 12.2-m). Tower configurations were changed due instrument availability and prevailing winds.For exact sonic location and pan configuration for each burn, see burn layout and documentation in the dataset: A Multiscale study of the coupling between flow, fire and vegetation: field experiments – burn layout and documentation (https://doi.org/10.60594/W4NC73, see Annotations section for Metadata link).three-dimensional (3-D) windthree-dimensional (3-D) turbulencewind directionwind speedwind vectorstemperaturecombustionheat fluxessensible heat fluxesconvective heat fluxesData Types and Measurement Variablesconvective heat transferplume dynamicsprescribed burnprescribed firepool firestatic firesmokelongleaf pine forestTall Timbers Research Station and Land Conservancynorth FloridaSavannah River SiteSouth CarolinaRC20-1362sonicsonic anemometerfire3-DNoneThis work is licensed under the Creative Commons Attribution 4.0 International License.

Ninety-two static pool fires were conducted on two sites in the southeast at Tall Timbers Research Station in north Florida and the Savannah River Site in South Carolina). Other datasets collected with this project include Terrestrial Laser Scans (TLS), temperature profiles and video.A multiscale study of the coupling between flow, fire and vegetation static field experiments: burn layout and documentation form 2022-2025 (https://doi.org/10.60594/W4NC73) describes the entire project including all datasets collected, sensor specifications and sensors arrangements surrounding the static pool fires.Manipulation of the canopy occurred at both sites.Tall Timbers: The burns occurred on approximately 0.5 ha clearing that had all vegetation was removed.Savannah River Site: All burns were conducted within a 2-ha loblolly and longleaf pine plantation with a row spacing of approximately 2.5-m. The trees in the plantation had an average height of 13-m and an average DBH of 21-cm. Burns 1-43 the understory vegetation was removed but canopy was left intact. Burns 44-67 the tree density was reduced by two thirds, removing every third row in both the east/west and north/south directions. Burns 68-85 increased understory vegetation and hurricane Helene damage occurred in the fall of 2024.Reference https://doi.org/10.60594/W4NC73 for burn configurations.The amount of fuel for each pool fire experiment was defined by the number and alignment of pans. Each pan is 0.5-m square and 5-cm deep and contained 7.6-L of fuel.Tall Timbers: Fuel consisted of 7.6-L diesel per pan.Savanah River Site: Fuel consisted of a 50/50 mix of vegetable oil and diesel fuel (3.8-L each).Reference https://doi.org/10.60594/W4NC73 for burn pan configurations.Tower and instruments were configured based on prevailing wind conditions.Tall Timbers: Nine sonic anemometers were mounted on nine aluminum towers downwind along three arrays (A, B, and C). Each array had sonics set at approximately 6, 10 and 30-ft (1.8, 3 and 9.1-m) heights above the ground. A single tower and instrument configuration was used at tall timbers. A control sonic was located 14.6-m upwind of the center pan on a 5-ft (1.5-m) tower.Savanah River Site: Nineteen sonic anemometers were mounted on 11 towers around the pan area. Multiple configurations were used to change in wind direction. Tower sensor heights remained constant, only the tower locations changed. Towers C and E were fixed and did not move.A towers (A1, A2, A3) had a single sonic mounted at 6-ft (1.8-m).B towers (B1, B2, B3) had a single sonic mounted at 10-ft (3-m).C, D and E towers (C, D1, D2, D3, E) had 3 sonics mounted at 10, 25 and 40-ft (3, 7.6 and 12.2-m).Tower and instruments were configured based on prevailing wind conditions.Reference https://doi.org/10.60594/W4NC73 for exact sensor locations.R.M Young 81000v sonic anemometers were used with factory calibrations, with average reported accuracies of 0.05 m/s for 3-dimensional wind speed, ± 2 degrees for horizontal wind direction, and ± 0.01 m/s for sonic speed of sound, resulting in a temperature accuracy of ± 2-50 (°C). Response above 50 °C is approximately linear up to around 100 °C.Specifications for the sonics can be found in the users manual ( 81000V-90L.pdf) provided in this dataset.The data includes a diagnostic code (DIAG) collected in the field that indicates when the instrument is not functioning properly. A zero diagnostic code indicates valid data, all other codes are suspect. Refer to the manual (81000V-90L.pdf) for specific diagnostic codes greater than zero. All data is provided, use suspect data at your own risk.Post-processingArchive time – datasets were cut to the archive start and end times listed in the BurnDate.csv (https://doi.org/10.60594/W4NC73).Missing data – TIMESTAMP and RECORD were added to align sensors, variables with missing timestamps were set to NaN.Error – error tables were created for each location identifying missing data from the start and end of each sensor and and the amount of suspect data with NAN or DIAG > 0.Graphs – HTML graphs were created for each sensor to visually inspect the data. Graphs only include valid data (DIAG = 0).Note – If a sensor malfunctioned or did not collect for the entire burn period, no data were archived.AlbertSimeoniWorcester Polytechnic Instituteasimeoni@wpi.eduhttps://orcid.org/0000-0002-5497-3794Principal InvestigatorU.
