The LOw Frequency ARray (LOFAR) is one of the world's largest low frequency radio telescopes with its core centred in the Netherlands, several stations scattered over different countries in Europe. Although the main use of the instrument is for radio astronomy, the flexibility of the system allows for many kinds of auxiliary science. The ionosphere, in itself an important contributor to calibration errors in our radio interferometric measurements, is studied intensively in various ways with LOFAR. In this presentation I will show the wealth of ionospheric information that can be extracted from the LOFAR data, using a number of different techniques, including single station observations and also various ways to combine the ionospheric information on short and long baselines.
