To use this code, you *must* have gridded reanalysis or climate model data that contains variables described below.

**A sample of gridded data + TC trajectories to start with can be downloaded from:** http://www.colinzarzycki.com/files/ERA-sample-ETC-tracker-data.gz

The time dimension must be the record dimension and have a CF-compliant units attribute (i.e., "days since 2000-01-01"). There should also be a calendar attribute if using a calendar other than "noleap"

Files may only be split along the time dimension. In other words, PSL, UBOT, VBOT, and Z at time t must be on the same file, but files can be split to have a single time per file, 4 times per file, 1460 times per file, etc. Any files with more than one month of data will occur additional memory overhead, so daily/weekly/monthly are preferred.
