This dataset includes integrated vapor transport (IVT), calculated from ERA5 reanalysis, for 6-hour periods from 1979-2020 that have identified atmospheric rivers. Four different NetCDF files have been produced with different atmospheric river detection criteria:


1. Length of 1500 km; > 500 kg m-1 s-1 IVT (era5_ar500_nohurr.nc)

2. Length of 1500 km; > 750 kg m-1 s-1 IVT (era5_ar750_nohurr.nc)

3. Length of 2000 km; > 500 kg m-1 s-1 IVT (era5_ar500_2000_nohurr.nc)

4. Length of 2000 km; > 750 kg m-1 s-1 IVT (era5_ar750_2000_nohurr.nc)


These datasets have been filtered to remove any tropical cyclone driven atmospheric rivers by using HURDAT2 to cross-reference. The dependent variables, u-wind, v-wind, and specific humidity are derived from ERA5 reanalysis (https://www.ecmwf.int/en/forecasts/datasets/reanalysis-datasets/era5).
