This is a revised version of the Livneh et al. precipitation data sets that does not split up the precipitation observations by day.
For more information see:
David W. Pierce; Lu Su; Daniel R. Cayan; Mark D. Risser; Ben Livneh; Dennis P. Lettenmaier, 2021: An extreme-preserving long-term gridded daily precipitation data set for the conterminous United States Journal of Hydrometeorology, v. 22 p. 1883, https://doi.org/10.1175/JHM-D-20-0212.1
I've also included a copy of the Livneh et al. 2013 data set with the extension by Lu Su of UCLA that extends Tmin, Tmax, and winds from 2012 through 2018, which matches the temporal coverage of the unsplit precipitation data set.

Updates:
2021-05-02: Lu Su fixed an issue with normalizing to the desired climatology, which is Livneh et al. 2015 over the period 1981-2010. Before, it was not normalizing to climatology over this period.
