Results from the ISSI Langmuir Probe Workshop: A 100-Year Workhorse, Easy to Fly but Difficult to Interpret

What is it about?

This paper summarizes our work on the correct way to use a common type of antenna known as a Langmuir probe in space. Langmuir probes are often the only way to measure temperature of the free electrons in the ionosphere.

Why is it important?

Langmuir probes are inexpensive, easy to make and apparently simple to use. This paper concerns the authors efforts to record and publish 75 years of accumulated lore.
