Dear Karl

I agree. Alison is doing a phenomenal job, and Martin has also been making
great efforts in dealing with many different requests. Thank you.

Best wishes

Jonathan

The standard name changes have also been published on the NERC Vocabulary Server and the area type changes will be added shortly. The full list of changes is given at the end of this message.

Due to the current high volume of names being processed, I will plan the next update to take place on 29th May.

These had aliases of integral_of_sea_water_temperature_wrt_depth_in_ocean_layer and ocean_integral_of_sea_water_temperature_wrt_depth, respectively. The two existing names and their aliases have now all been turned into aliases of one current name.

> >Sebastien Villaume asked how to specify the limits of an integral calculated over the full depth of the ocean or atmosphere (http://mailman.cgd.ucar.edu/pipermail/cf-metadata/2018/060018.html). It was agreed to amend the definitions of all integral_wrt_depth|height names to read as follows: 'The phrase "integral_wrt_X_of_Y" means int Y dX. To specify the limits of the integral the data variable should have an axis for X and associated coordinate bounds. If no axis for X is associated with the data variable, or no coordinate bounds are specified, it is assumed that the integral is calculated over the entire vertical extent of the medium, e.g, if the medium is air the integral is assumed to be calculated over the full depth of the atmosphere.' Previously the definitions provided no instructions for the full depth case. This change affects the following 11 names.

> >'Radiative flux is the sum of shortwave and longwave radiative fluxes. Scattering of radiation is its deflection from its incident path without loss of energy. The volume scattering function is the intensity (flux per unit solid angle) of scattered radiation per unit length of scattering medium, normalised by the incident radiation flux. The (range of) direction(s) of scattering can be specified by a coordinate of scattering_angle. A coordinate variable of radiation_wavelength or radiation_frequency can be specified to indicate that the scattering applies at specific wavelengths or frequencies.'
