Data File Type 2 - Furuno WR110 Operator's Manual

7.3.2. Data file type 2(scn, and others)
1) Record unit
Each scn file includes one scan data (e.g. one round in azimuth) which is stored in a capture folder
specified in RainMap acquisition setting.
2) Record file name
Note 1: (*1) is applied only for scn version 3.
Note 2: scn version 3 is recorded under RainMap version 4.0 and later version. And the earlier RainMap
version records scn format version 2.
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, .scnd
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", "sppi", and "scnd" 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.
3) Data format
Note 1: (*1) is applied only for scn version 3.
Note 2: scn version 3 is recorded with RainMap version 4.0 and later version. And the earlier RainMap
version records scn format version 2.
