[Go-essp-tech] Data file gaps

[Jennifer Adams]

Dear All,
I have a GrADS script that creates descriptor files for CMIP5 data, and it has uncovered some gaps in the date strings of files that belong to an atomic data set. I have checked the ESGF gateways for all the datasets listed below and I can confirm that these files are missing for some variables. I haven't given the variable names, because I have only checked the subset of variables that are of interest to me and that may not be a complete list. If the specific var names that I checked would be useful, I can provide them. While checking on these gaps, I noticed that not all variables in an atomic dataset span the same time range … an inconsistency that doesn't quite make sense to me. I also noticed that in some cases, data files that I had grabbed are no longer listed on the gateway, even though the version number is the same. An example is cmip5.output1.NCC.NorESM1-M.piControl.day.land.day.r1i1p1.v20110901, mrsos, date range 11000101-12001231. What does that mean? 

The gaps put these data into the "not quite usable" category. I wasn't sure whether to send this to the helpdesk or the forum or both; in the end I am just posting here.
