Rainfall intensity-duration-frequency curves for Brazil: a large national database

Version 2: Data updated in 04-2026. Version 1 files were deleted. New equations added. Compilation of rainfall IDF curves for 6,550 rainfall gauges in Brazil. Includes curves established using: a) sub-daily rainfall data (Standard), and, b) daily rainfall maximum depth (Disaggregation). Contents of each folder: 1. XLSX file - datasheet containing curves from Standard method and Disaggregation method, a Reference list's plan, and a Description's plan. Version 2: Standard and Disaggregation equations were joined at the same "plan". Columns added: type, years_number, low_duration_minutes, high_duration_minutes, and observation. See description's plan for more information. 2. GIS vector file in geopackage format: Version 2: includes on vector files with all Standard and Disaggregation equations. 3. GIS vector files in shapefile format: Version 2: one shapefiles compacted as RAR file with all Standard and Disaggregation equations. 4. GIS vector files in geojson format: one files with all Standard and Disaggregation equations. Version 2: one files with all Standard and Disaggregation equations.
