Impact of adjusted and non-adjusted surface observations on the cold season performance of the Canadian Precipitation Analysis (CaPA) System

This dataset contains output of the precipitation estimates over central Canada during the winter seasons from 2019 to 2022 of the Canadian Precipitation Analysis (CaPA) System developed by Environment and Climate Change Canada. Two approaches were tested and compared with the control run (CTRL). First, the wind speed threshold during the quality control procedure in CaPA was modified to increase the number of observations assimilated as QC. Second, the automatic solid precipitation measurements were adjusted using a universal transfer function as TF. These data are associated with the article "Impact of adjusted and non-adjusted surface observations on the cold season performance of the Canadian Precipitation Analysis (CaPA) System" by Feng et al., submitted in 2023.
