New journal articles on the HRRR system

[EricJames-NOAA]

I'm pleased to announce that several peer-reviewed journal articles on the HRRR system have recently been published online through the American Meteorological Society.

HRRR overview part 1 (description): https://doi.org/10.1175/WAF-D-21-0151.1
HRRR overview part 2 (performance): https://doi.org/10.1175/WAF-D-21-0130.1
RAP/HRRR radar reflectivity assimilation: https://doi.org/10.1175/WAF-D-21-0142.1
RAP/HRRR land / snow data assimilation: https://doi.org/10.1175/JHM-D-21-0198.1
RAP/HRRR stratiform cloud analysis: https://doi.org/10.1175/MWR-D-20-0319.1
Economic impact of HRRR: https://doi.org/10.1175/BAMS-D-20-0099.1

These papers should all be open access once they are published in an issue. These articles should help provide some details for downstream users about the model initialization and configuration used in the operational HRRR.
