Dear All,
I have been keeping my head down for the last few days because I have
been putting a lot of time into preparing the table update that was
planned for this week. The file is just about ready but I am going to
be away over the weekend and I don't want to apply the update to the
website in a great hurry today, in case I mess it up. I will therefore
postpone the update until Tuesday 15th April.
I am aware that there is currently a lot of discussion taking place
regarding standard names and I will catch up with it all as soon as the
update is finished.
Cheers,
Alison

> toa_shortwave_cloud_radiative_effect; Wm-2
> toa_longwave_cloud_radiative_effect; Wm-2
> toa_cloud_radiative_effect; Wm-2
>
> The explanations of these names will point out that "cloud radiative
