Data for: "Maximum Certainty Principle applied to rainfall modelling and regionalisation in Ecuador"

This dataset contains the input file and output products used in the MIT-Q rainfall modelling workflow for the Metropolitan District of Quito (DMQ; 2500 km²). The Input folder includes the annual isohyet file (Isoy_Raster2026.txt). The Output folder contains seven subfolders with: (i) a calibrated 500-year storm catalogue for the DMQ (Tor_MIT25G10_500N.txt) generated with MIT-Q Module 1; (ii) virtual hyetographs for calibrated and validated stations (500-year simulations; e.g. CentAer.txt; time in hours and precipitation in mm) generated with MIT-Q Module 2; (iii) station-based virtual rainfall intensities (mm h⁻¹) for multiple durations (5 min to 24 h; e.g. IntensiAer.txt) generated with MIT-Q Module 2; (iv) calibration/validation spreadsheets for Quito-Observatory and four additional stations (Aeropuerto, Iñaquito, Izobamba, and Tola)(Support Material for Figure 5); (v) outputs from a 1.0 km-spaced virtual station network (recording intensities and event counts with PRE ≥ 0.1 mm) generated with MIT-Q Modules 3–5(Support Material for Figure 6); (vi) a burst-comparison folder comparing the number of rainfall bursts (Support Material for Figure 2, 4 and 8); (vii) a short-duration versus daily-intensity correlation analysis (Dur < 2.0 h; low correlation with daily intensity); and (viii) an IDFP Ecuador analysis for 66 INAMHI stations (including a GeoGebra example for station M-003 Izobamba)(Support Material for Figure 9).
