I found a lot of information how to create an ESRI grid from NetCDF without ever finding a list of requirements for the NetCDF format. CF compliant does not seem to be enough for ESRI sometimes. What I want to do is to produce CF compliant NetCDF that loads directly into ESRi's ArcGIS without any further processing. I will have 2 and 3 dimensional data plus time as (unlimited) dimension. Since I do not have access to ArcGIS myself I am looking for a kind of spec for the NetCDF.
