 ELDA Products
 ----------------
 This section describe the structure of ELDA products.
 ELPP Products: dimensions
 ~~~~~~~~~~~~~~~~~~~~~~~~~
 Aerosol optical products have the wavelength dimension (accommodating products at different wavelength in the same variable) and time dimension (accommodating different profiles in the same time series). The altitude dimension is defined for reporting the information as a function of the altitude. The dimension nv is used following the cf convention whenever a bound is needed for some evaluation. In our case nv is used for defining variables which have per definition some bounds as time_bounds reported below.
 The following dimensions are defined in ELDA products:
 -  time
 -  altitude
 -  wavelength
 -  nv
 The dimension *time* (mandatory) specifies the number of vertical profiles included in the product timeseries.
 The dimension *altitude* (mandatory) represents the number of rangebins characterizing each vertical profile
 The dimension *wavelength* (mandatory) indicates the number wavelengths for which the optical variables are provided
 The dimension *nv* (mandatory) is ancillary and it is always set to 2.
