9 ELPP Products: dimensions
10 ~~~~~~~~~~~~~~~~~~~~~~~~~
11
12 The following dimensions are defined in ELPP products:
13
14 - time
15 - level
16 - channel
17 - depolarization
18 - angle
19 - nv
20 - nc
21
22 The dimension *time* (mandatory) specifies the number of RCS (for each channel)
23 composing all the pre-processed time-series reported in the products.
24
25 The dimension *level* (mandatory) represents the number of rangebins characterizing
26 the pre-processed RCS.
27
28 The dimension *channel* (mandatory) indicates the number channels at which the RCS
29 time-series included in the product refer to.
30
31 The dimension *depolarization* (optional) indicates how many volume depolarization time-series are included in the products.
32
33 The dimension *angle* (mandatory) takes into account how many zenith scan angles have been used to measure the RCS time-series reported into the products.
34
35 The dimension *nv* (mandatory) is ancillary and it is always set to 2.
36
37 The dimension *nc* (optional) is ancillary and provides the number of channels involved in the calculation of RCS or volume depolarization time-series.
