What

When

CMAQ v5 Move to Cray, upgrade with improved aerosol chemistry and emissions with 2011 base year estimates; update BlueSky smoke emission system; include 24-h pre-analysis for smoke initializationm use NGAC aerosol lateral boundary conditions; update PM Bias correction Summer 2017
RTMA/URMA v2.6, PCPANL v3.0 Implement “GLERL adjustment” to coastal obs near Great Lakes; Add cloud cover, cloud ceiling analysis, unified terrain for OCONUS; 15-minute CONUS RU-RTMA output; Add dew point, wind, ceiling and visibility to airport listings for FAA; Hourly URMA for ConUS and Puerto Rico (requirement from MDL/NBM); Add significant wave height analysis; start use of UrbaNet observations; Loosen obs QC tolerances on mesonet temperature and moisture; Add min/maxRH analysis (all domains); Use EMC/GFE unified terrain and land/sea mask for OCONUS domains; Hourly QPE from Puerto Rico; For CONUS: currently the Stage IV hourly does not cover Northwest RFC and CA/NV RFC domains (due to lack of hourly input). For this implementation, use the hourly gauge-corrected MRMS to dis-aggregate the 6-hourly QPE from Northwest RFC and CA/NV RFC into hourly amounts, then combine them with the hourly QPEs from the other 10 RFCs, to cover the entire CONUS. Fall 2017
Short-Range Ensemble Forecast System (SREFv8) Move SREF to Cray; update to latest version of WRF/NMMB model Fall 2017
HREFv2/HIRESWv7 Increase horizontal resolution of existing members from 4.2 km to 3.2 km; add "NSSL" WRF-ARW member (to operationalize Storm-scale Ensemble of Opportunity (SSEO); enhance HREF ensemble products, add OCONUS product generation. Fall 2017
RAPv4/HRRRv3 Upgrade to WRF 3.8.1; add storm-scale hybrid DA (tentative); Alaska HRRR (tentative); upgrade MYNN PBL and surface physics; improve surface data and cloud assimilation; enhancement of land-sfc model Winter 2018
