1.0 Data Set Overview
	Introduction: This uses the HRRR model soundings and RALA to create .nc files of surface precipitation phase and liquid water fraction using the spectral bin classifier.
	Time period covered: 2019/01/28/21:00-2019/02/08/23:00
	Physical location: CONUS (38.883º, -77.017º)
	Data source: High-Resolution Rapid Refresh (HRRR) Model and Multi-Radar/Multi-Sensor System (MRMS)
	Web address references: N/A

2.0 Instrument Description: N/A


3.0 Data Collection and Processing
	Data collection: N/A
	Derived parameters/processing techniques: see references in section 6.0
	Quality assurance and control procedures: see references in section 6.0

4.0 Data Format
	Data file structure: NetCDF (.nc)
	Data format/layout: Identical grid and temporal resolution as HRRR model
	Parameters: Precipitation phase (SBCv3) and Liquid water fraction (lwf)
	Data version: V10
	Description of flags, codes used in data, and definitions: 
		No data flagged as -999
		LWC given as percentage
		SBC==1 > RA
		SBC==2 > RASN
		SBC==3 > SN
		SBC==4 > FZRA
		SBC==5 > FZRA
		SBC==6 > FZRA
		SBC==7 > FZRA
		SBC==8 > FZRAPL
		SBC==9 > PL
		SBC==10 > PL
		SBC==11 > PL

5.0 Data Remarks
	PI'S assessment of data: No precipitation phase is given unless there is echo.  Shallow precipitation that is overshot by neighboring radars will not have a phase provided.
