Dataset problem: GISS-E2-1-G/ssp126/r1i1p5f1/Omon/tos/gn has wrong units

[bouweandela]

Describe the dataset issue A clear and concise description of what the problem with the data is is. Here are some guidelines that you can use right out the box by filling in the blanks (note that, if needed we will assist you with writing a fix; also note that if the problem is with a CMIP6 dataset, we will alert the ESGF and/or the model developers for them to fix the problem in the long run; fixes for CMIP5 by the model developers are no longer possible):

• Data file has been changed by you in any way (if you answer yes the issue will be void and closed, we are not supporting custom-made datasets that present problems, it is your resposability to fix those problems): no

• Project (CMIP5/CMIP6/OBS/obs4MIPs/etc): CMIP6

• Full dataset description (fill out as many as you know, please):

  • dataset: GISS-E2-1-G
  • experiment: ssp126
  • mip: Omon
  • ensemble: r1i1p5f1 (the other ensemble members look fine)
  • grid: gn
  • version: v20200115
  • variable used: tos

• Problems encountered (please describe what the actual problems are: e.g. wrong standard name, issue with dimensions): The units are decC, but the values are in Kelvin.

• Pointer to existing copy of data on ESGF node (it would be very useful if you could provide a physical fullpath to the file(s) that are causing the problem, e.g. on CEDA Jasmin or DKRZ): on DKRZ/Levante: /work/bd0854/DATA/ESMValTool2/download/CMIP6/ScenarioMIP/NASA-GISS/GISS-E2-1-G/ssp126/r1i1p5f1/Omon/tos/gn/v20200115/tos_Omon_GISS-E2-1-G_ssp126_r1i1p5f1_gn_201501-205012.nc

you sure about this? I mean, 272.2487C is a perfectly fine temperature for cooking a (very fast) pizza :grin:

I don't usually cook my pizzas on the sea surface though 🤣
