Frequency combs are a powerful sensing tool capable of measuring broadband spectra with high resolution and high precision. The diffraction limited output of these devices is well suited to measuring long open-air paths and the combs themselves are becoming robust, compact, and transportable. Here we seek to employ frequency combs for atmospheric monitoring, and we are looking for impacts that can be made by their unique combination of measurement abilities.
