For example some data from the Omon table of NorESM2-LM were available from dkrz a year ago, but now no longer are found (see https://cp.copernicus.org/articles/21/299/2025/cp-21-299-2025-supplement.pdf).
Just 2 months ago I downloaded (via https://esgf-node.llnl.gov)
t_hetao_Omon_NorESM2-LM_lig127k_r1i1p1f1_gn_215101-216012.nc_
for example,
but when I look for NorESM2-LM_lig127k now, via https://esgf-metagrid.cloud.dkrz.de/ I don't see the Omon Table at all (other tables are found).
