Data and code for: Projected expansion of the summer monsoon rainfall regime across districts of Pakistan

Derived data and code for the paper Projected expansion of the summer monsoon rainfall regime across districts of Pakistan (submitted to Communications Earth & Environment). Each of Pakistan's 160 districts, and each grid cell, is classified as monsoonal or not from the annual range (> 2.5 mm/day) and summer share (> 0.55) of its rainfall, in five observational products (1950–2025) and 34 NEX-GDDP-CMIP6 v2.0 models (1950–2100, SSP2-4.5 and SSP5-8.5). Contents (one zip per group; every zip contains MANIFEST.csv with the MD5 sum of each file): code: snapshot of https://github.com/owaisali07/pk-monsoon-regime (notebook, section sources, tests, outputs, manuscript build) district precipitation series, 34 NEX-GDDP-CMIP6 v2.0 models × historical/SSP2-4.5/SSP5-8.5 (parquet) district precipitation series, CHIRPS, IMERG, ERA5-Land, scaled ERA5-Land, CPC (parquet) yearly seasonal grid statistics per NEX-GDDP-CMIP6 model and scenario (NetCDF) yearly seasonal grid statistics of the observational products (NetCDF) per-model CMIP6 district classes, crossing years, projections and skill weights CMIP6 large-ensemble district rates and GPCC seasonal grids (NetCDF) ERA5 850 hPa moisture-flux fields and composites (NetCDF) observed membership, crossing and onset/withdrawal results (CSV) data inventory, NEX-GDDP artefact scan and clean-run log The raw inputs are public and not redistributed here; their sources and download scripts are documented in data/README.md of the code. Access is restricted until the paper is accepted.
