I don't think that you have to open the files on every processor. I think that you can:

1. In the first iteration, the processor 0 can open the file and write out the header.
2. Close the file.
3. Then, which every processor has the satellite on it, it opens the log file in append mode, writes the line of data, and closes the file.

Then you don't have to have a combine python code at the end. Does this make sense, or am I not thinking about this the right way?

Also, we should test to see if this works with ensembles - we probably have to add the ensemble number if this wasn't added.
