As requested, here is the list of customUnits used by sbclter (to date). The
current version of this list can be found at the url above. Several of these
units need addional attributes or definition. These are commonly-used units in
oceanography and limnology.

Changing QA contact to the list for all current EML bugs so that people can
track what is happening.

Original Bugzilla ID was 1634

[mobb]

2018-06-28 line 1070
added inverseMeter, inverseCentimeter, deprecated waveNumber (in favor of inverseMeter)

[mobb]

Not adding: einsteins; recommendation is to use moles instead.
added irradiance and spectral irradiance units in watts, also for solid angles. eg
wattPerMeterSquaredPerSteradian, wattPerMeterSquaredPerNanometer
(common ones from optics instruments only. a person could go nuts with these)

[mobb]

added

• permil (analog to percent)

a few more concentration units:

• mmol per meter cubed
• micro, milli and Equivalents per Liter (conductivity in water)
• siemens per cm

[mobb]

and some primary production units (gotta have 'em):
milligramPerMeterCubedPerDay
milligramPerMeterSquaredPerDay
these are for aquatic; the terrestrial units were already there.

[mobb]

TO DO: units are all added, but don't close till you review the descriptions. still finding copy-paste cruft.

[mobb]

descriptions ok. closing. yay.
