Haramain Train Stations
A comprehensive statistical analysis of climatic conditions across Haramain high-speed railway stations in Mecca. The study examined temperature, humidity, wind patterns, and other environmental variables to support operational and safety decisions.
Project highlights
Methods & Tools
Characterizing long-term climate and dust-exposure trends along the Haramain corridor required harmonizing multi-decadal records and quantifying spatial patterns with defensible statistical trend tests.
We assembled and quality-controlled multi-era climate records, tested for monotonic trends, and mapped spatial variation across the full corridor.
Harmonized and quality-controlled climate records across 3 eras and 12 variables, screening for inhomogeneities and gaps before analysis.
Decomposed the time series and tested for monotonic change with Mann–Kendall and Sen's-slope estimators, accounting for seasonality and autocorrelation.
Modeled and interpolated spatial variation with kriging and produced corridor-wide GIS exposure maps in R (sf/terra) and QGIS.
Quality-controlled, analysis-ready multi-era climate dataset.
Trend-analysis report with significance testing and effect sizes.
Geospatial exposure maps with reproducible analysis code.
Records screened for inhomogeneity and gaps before any trend test.
Trend tests adjusted for seasonality and autocorrelation.
Spatial interpolation cross-validated (leave-one-out) for accuracy.
Reproducible R/QGIS workflow with documented data provenance.
Our work was not medical at all — we were studying the climate around the Haramain train stations: temperature, humidity and wind across different periods. They built the statistical analysis and the GIS maps together, and the results helped us in real operational and safety decisions. Very professional people.
