Data Format Descriptions
Radar Hourly RASS Files Produced By POP [v4.1]
FILE NAMING CONVENTION:
SSSYYJJJ.HHt
where
SSS = SiteID
YY = Year
JJJ = Julian Day
HH = Hour
Date and time are in UTC and represent the start time of the average.
DATA DESCRIPTION:
Line 1: BLANK LINE
Line 2: " SSS" "additional info. (optional)" where SSS = 3 letter station ID
Line 3: " RASS rev 4.1" (rev number will change if file format changes)
Line 4: [for station] latitude (N); longitude (W); elevation (m)
Line 5: date; begin time of consensus; UT offset (minutes)
[format " yy mm dd hh mm ss ut_offset"]
Line 6: consensus averaging time (minutes); number of beams; number of range gates
Line 7: [format "num:tot (window) "]
number of records required to make consensus (num)
total number of records (tot)
the consensus window size (m/s)
Line 8: number of coherant integrations
number of spectral averages
pulse width (ns)
inner pulse period (ms)
Line 9: full-scale Doppler value (m/s)
delay to first gate (ns)
number of gates
spacing of gates
Line 10: azimuth; elevation (degrees)
(if elevation > 90 then it is in degrees*100)
Line 11: Labels for columns of data that follow
Line 12: Start of data
[A LINE FOR EACH RANGE GATE, INCLUDES THE FOLLOWING]
Height above ground (km)
Uncorrected RASS temperature consensus (deg C)
Corrected RASS temperature consensus
Vertical wind consensus (w-component, positive upward, m/s)
Number of records that made consensus (for the 3 values in same order)
Average SNR (dB) of records in consensus (in same order)
LINES 1-12 REPEATED FOR EACH ADDITIONAL MODE CONFIGURATION
