Hysteresis of extreme precipitation in East Asia under multiple pathways to carbon neutrality

This dataset provides extreme precipitation indices derived from UKESM1 simulations performed by the National Institute of Meteorological Sciences (NIMS) under multiple carbon neutrality scenarios (A–D). The scenarios follow the CDRMIP and ScenarioMIP experimental protocols, including ±1% and ±2% per year CO₂ ramp-up and ramp-down pathways. The indices are calculated following the ETCCDI definitions and include Rx5day, Rx1day, R95, R99.
