Python utilities for reading and plotting TOLNet data.
TOLNet data provides information on the vertical evolution of ozone at sites around the country. The recent API makes accessing the data easier, and this utility provides an interface for the API to connect TOLNet to xarray and pandas. This simplifies comparison of TOLNet to other datasets.
