description: Results files of the manuscripts under review Martins & Pinto (2026a) and Martins & Pinto (2026b), with respectively titles: “Development of an upper envelope curve of frequency factors for PMP estimation in tropical regions under convective regimes — a deterministic approach” and "Derivation of frequency factors for Probable maximum Precipitation (PMP) estimation using stochastic simulation of annual maximum precipitation in tropical convective regions".

The folder "01_tabular data" presents the results in tabular format (.xlsx and .geojson). The folder "02_IDW_upper_envelope_PMP" provides the spatializations of the PMP obtained by regional envelope for durations between 24 hours and 30 days, as well as for the 24-hour Hershfield PMP. Finally, the folder "03_IDW_synthetic_PMP" addresses the spatializations of the Synthetic PMP for durations between 24 hours and 30 days, associated with the 95% and 99% percentiles.
