. Otkin and Potthast (2019) assimilate a water vapor band on SEVIRI, finding that the all-sky radiance bias correction is critical to making a positive impact on analyses. Demonstration of GOES-16 Advanced Baseline Imager (ABI) RA was provided by Zhang et al. (2018 , 2019 ), and Jones et al. (2020) . These studies make different assumptions about how to inflate observation and background errors and how to weight information in the vertical. Errors in model microphysics and radiative transfer

.noaa.gov/big-data-project ). The latency requirement is particularly extreme for short-term forecasting of hazardous weather. Yet, improvements in NWP are driven by computationally intensive advances in all aforementioned areas. Examples of specific improvements for global medium-range NWP will include: enhanced assimilation of satellite measurements, including radiances affected by clouds, precipitation, and surface properties [requiring more complete radiative transfer (RT) models accounting for these effects], and using
