[CF-metadata] CF standard names for chemical constituents and aerosols

I want to make the CF group, and especially those interested in chemical
constituents, aware of the naming practice adopted by the instrument science
teams for the NASA Aura satellite.

The data format is not netCDF but rather HDF-EOS5, which is to HDF5
similarly as netCDF4 is to HDF5. At some point, cross-walks must be
developed to bridge the vocabularies.

A good deal of thought and effort was put into developing consensus on the
naming conventions adopted by the Aura Data Format Working Group. These
describe existing products under routine production and distributed by NASA.
The Aura practice is documented as "ESDS-RFC-009, Aura Guidelines Technical
Note" at:

http://www.esdswg.org/spg/docindexfolder

The equivalent "common names" are documented in section 5.1.4 Swath Data
Field Names, 5.2.4 Grid Data Fields, and 5.3.4 Zonal Average Data Fields
