Data File Type 2 - Furuno WR2120 Operator's Manual

5.2. Data File Type 2 [ scn v3 ] (legacy format)
1) Record unit
Each scn file includes one scan data (e.g. one completed azimuth rotation) which is stored in a
capture folder specified in RainMap acquisition setting.
Note: (*2) is only for Dual Polarimetric Dopplar.
2) Record file name
File name: Product number (xxxx) (*1) _ Scenario start time (YrMoDa _ HrMinSec) _ Elevation angle
number (## ) [deg] _ Tx pulse type (**) .scn
File name extension: .scn, .rhi, .sppi,
xxxx_YYYYMMDD_hhmmss_##_** .scn
e.g.: 0001_20130514_123400_01_00
Product number: alphanumeric
Scenario start time: UTC
Elevation angle number is numbered from the lowest angle as 01, 02, 03･･･
Tx pulse type
00: pulse modulation, 01: frequency modulation (pulse compression), 02: 00 + 01 (alternative)
*File format of "rhi" and "sppi" are also same.
The case of SRHI, File name: Product number + Scenario start time (YrMoDaHrMinSec) + Serial
order (rhi)
Product number + Scenario start (YrMoDaHrMinSec) + Serial order
e.g..: 0001_20170714_140100_001.rhi
SRHI azimuth start to end point or end to start point will be scenario start YrMoDaHrMinSec. Serial
order will be changed by every azimuth (It will add serial order by moving upper and lower direction of
elevation.
