Dataset for "Multi-scale analysis of flow over heterogeneous urban environments"
Description
This dataset accompanies the paper
Multi-scale analysis of flow over heterogeneous urban environments (2025).
Maarten van Reeuwijk and Jingzi Huang
Boundary-Layer Meteorology
If you make use of this dataset, please cite both the paper and the dataset.
# ------------------------------------------------- #
The main directory contains the following files and folders:
Functions/: Auxiliary MATLAB functions.
Figures/: All the figure files from the paper.
Data/: Raw simulation data.
main.m: Loads the simulation data and reproduces the figures in the paper.
coarsegraining_example.m: an example of efficiently implementing the coarse-graining method in convolution form using Fast-Fourier Transform --- the core of the multi-scale analysis.
# ------------------------------------------------- #
Data folder:
Simulation geometry:
geom.stl
Local time-averaged data (x,y,z)
tdump.302.nc: contains 3-D fields of variables and budgets.
Time- and plane- averaged data (z)
xytdump.302.nc: contains intrinsically averaged vertical profiles of variables and budgets.
Facet time-averaged data
fac.302.nc: contains variables defined on solid facets.
Additional simulation data
facet_sections_*: information on solid facets.
fluid_boundary_*: information on fluid-solid boundary.
solid_*: information on solid areas.
namoptions.302: preset simulation parameters.
# ------------------------------------------------- #
Functions folder:
Matlab/: supporting the 'udbase' post-processing class, which reads key input parameters and provides methods to load both field and facet data. Adding it to the path before using 'udbase'.
Filter_fft.m: a function that implements the Fast Fourier Transform.
