Tritium data modeled by WRF with TAWMP_HTO scheme

This dataset contains model output from four high-resolution mesoscale simulations performed with the isotope-enabled WRF model using the custom microphysics module TAWMP_HTO, which explicitly tracks tritiated water (HTO) in atmospheric hydrometeors. The simulations correspond to a convective case study and represent combinations of two initial tritium profiles (P1, P2) and two isotopic fractionation settings (C1, C2): Case1_P1C1.nc: profile P1, fractionation C1 Case1_P1C2.nc: profile P1, fractionation C2 Case1_P2C1.nc: profile P2, fractionation C1 Case1_P2C2.nc: profile P2, fractionation C2 Each NetCDF file contains one model time step (index 15) and includes 3D fields of: HTO (tritiated water concentration, kg/kg) TU (Tritium Units, dimensionless isotopic ratio) for six hydrometeor phases: vapor, cloud, ice, snow, graupel, and rain. All variables are defined on the native WRF grid and include geographic coordinates for spatial referencing. TU values are calculated as the HTO-to-water ratio scaled to the standard definition (1 TU = 1 tritium atom per 10¹⁸ hydrogen atoms), allowing direct comparison with environmental tritium observations.
