v1.0 SUBC record

See v1.0 Record Format Tables for the record structure outside of payload.

v1.0 SUBC ETA/SIGM record

This kind of SUBC record is employed to describe vertical grid structure. You can get pressure by p[k] = b[k] * (p_surface - c) + a[k], where k is the index of vertical plane and p_surface the surface pressure.

v1.0 SUBC TDIF record

This kind of SUBC record is employed for time integration/average product within the dataset for snapshot value (type2 = ??SV). The size of SUBC TDIF record depends on parameters n_dc (members) and n_vt described in CNTL record.

DATA records that refers this SUBC TDIF record has its element name beginning with underline ('_') in addition to that of NuSDaS Element Table.

...n_dc * n_lv * 4float [n_dc][n_lv]span: integration time span (in seconds)

v1.0 SUBC RADR record

This kind of SUBC record is used for datasets of radar observation. The size of SUBC RADR record depends on parameters n_dc (members), n_vt, n_lv, and n_el described in CNTL record.

Value of flags has these means:

0

ND.

1

Echo exists.

2

No echo exists.

3

No operation.

v1.0 SUBC ISPC record

This kind of SUBC record is used for datasets of synthesized multiple radar observations. The size of SUBC ISPC record depends on parameters n_vt, n_lv, and n_el described in CNTL record.
