Dear all
I haven't checked through the email archives, but my recollection is that we
decided to use the term solar_irradiance without "total" because "total" is a
comparative word that doesn't help you to understand the concept unless you
know the context.
Best wishes

Dear Martin,
I think that there has been some misunderstanding on my part, pointed out by
Jim's e-mail and there is currently no Standard Name for what is often termed
'solar irradiance' in observation data sets.
Should we proceed with the three new Standard Names suggested by Jim?
Cheers,
Hello Roy,
maybe .. but I was talking about the current definition of the CF standard name
"solar_irradiance", which, currently, has nothing to do with the vertical,

Hello Martin,
Isn't that was what cosine collectors on radiometers are for? I thought they
resolved the vertical component of the radiation within the hemisphere sampled.
Cheers, Roy.

Hi.
I must respectfully disagree with any change to the solar irradiance
definition. The definition is accurate and correct, whether you are a
solar physicist or an oceanographer. The Wikipedia article on solar
irradiance gives good definitions for the various specific terms.
Hello again,
What we map to the 'solar_irradiance' Standard name are parameters such as
'Downwelling vector irradiance as energy of electromagnetic radiation (solar
wavelengths) in the atmosphere by pyranometer'. So in the use case I was
thinking of it's both a horizontal surface and a
Dear Roy,
If we were starting from scratch I would recommend the following:
Solar irradiance is the power per unit area of the solar radiation received
from above at horizontal surface. It is distinct from the Direct Normal
Irradiance (which refers to radiation received by a surface
Dear Martin,
I agree that the current definition reflects more an astrophysics textbook
rather than common usage of the Standard Name and so I would support tweaking
the wording as you suggest. Care to come up with the replacement wording to be
used?
Cheers, Roy.
Please note that I
Hello Roy,
I suspected that there might be such a usage ... but don't you agree that the
current CF definition, which I've quoted below, is inconsistent with this? But
it could be adapted with a small change of wording,
