What

When

RTMA/URMA/RTMA-RU v2.7, PCPANL v3.1 Improve RTMA-RU product latency to 15 minutes after analysis time; Update background error covariance model to include flow-dependence; Improved observation quality control, especially for winds; New, unified terrain and land-sea mask for Alaska; Begin using mesonet visbility observations and CLARUS QC’d obs; Add ceiling height and sky cover analysis to OCONUS domains; Enhance ceiling height and visibility analysis through improved algorithm; Address precipitation coverage gaps near CONUS coastlines; Add significant wave height analysis to OCONUS domains; Remove legacy coarse-resolution output grids; Fall 2018
HREF v2.1 Unify products among constituent models, refine generation of probabilistic output, add bias correction. Add extended HRRR runs as new members, add Recurrence Interval QPF exceedence products. Fall 2019
