Hi again,I'm sorry to ask so many questions, i am looking around before asking these..My next problem is that I'd like to define a 'virtual variable' that is the result of simple operations on existing variables, for example a new variable that is the sum of 2 existing ones.I have read all about aggregating between datasets and over dimensions such as time, but i think this is different. My goal is to have a virtual WMS layer that is the result of the relationship between existing variables.Does this sort of functionality exist at this stage, or should i be pre-processing the dataset before the thredds stage ?
This functionality is available with the Ferret-THREDDS Data Server. It's a little tricky to install as a stand-alone service, but it can be done and you can use it to define complex virtual variables based on the existing variables.
