Dear Ajay
You could record this informally in the cell_methods e.g.
time: mean (few observations before the mid-20th century)"
Cheers
Jonathan

> What is the CF guidance for climatological bounds when the statistics being

> We're developing a climatology for nutrients such as dissolved oxygen,
> nitrate, phosphate and silicate.
> These make use of sparse observations from as early as the late 1800s. Up
> until the mid 1900s the number of observations have been few and spaced
> out. Since then there has been a big spike in the number of nutrient
> observations.
>
> Since old observations are important, we would like to use them in
> generating stats and deriving climatologies.
> At the same time having climatological bounds beginning at 1875-01-01,
> gives a false sense of the scope/ temporal extent of the climatology. Is
> there a way to capture this information in either the bounds/ stats
> variable?
