because "flux" means "flux per unit area" and radiative fluxes in CF are always radiative energy fluxes). Is there any difference between TOA incoming radiative flux (in W m-2) and horizontal irradiance that I am missing? regards, Martin F

Re: [CF-metadata] Standard_name proposal for volcanic ash and radioactive particles

Dear Jonathan, I think the number of possible isotope names is relatively small (<100 - please correct me if I'm wrong) compared to the thousand upon thousand of possible biological taxa. If so, I wonder if normalising out the isotope name is worth the effort of maintaining the standard list

onfusing to me. The term 'a platform that is nominally at rest' does not apply to many platforms for which heave is calculated; the original version of that, 'a moving object above the vertical level of that object when stationary' was maybe a little more clear... if also a little wordy. And, th
