Take the FFT of the CO2/methane data of the most recent monthly average CO2 data of any of the the stations listed in (https://www.esrl.noaa.gov/gmd/dv/data/index.php?category=Greenhouse%2BGases&parameter_name=Carbon%2BDioxide&frequency=Monthly%2BAverages)).

In particular fullfill three tasks (one for each group member):

Task 1:

• Write a function that calculates the actual frequency in useful units.
• Determine the frequency (ideally with a function) of the peak(s).

Task 2: Use some combination of waveform modification (which may include padding, windowing, taking the FFT, manipulating the waveforms, inverse FFT, and undoing the window+padding), to do the following:

• Clean up either high or low frequency noise (depends on your data) in the time domain by zeroing the appropriate waveform coefficients in the frequency domain.
• Plot both the "raw" and "cleaned" spectra in the time domain.

Task 3:

• Write the documentation
• Reuse github actions for linting and unit tests
• write unit tests for Task1 and Task 2

For this you have to complete the following steps:

• Discuss with the other groups using issues which station data you will use. Each group should use a different one.
• Discuss in this repository using issues who will do which task (specified above)
• Discuss who should be the main responsible for the repository (the one that can accept merge requests, let me know in discord so I can adjust rights)
• Discuss and generate milestone for your project to optimize the timeline of your project
• Discuss and generate labels for your issues
• Fork this repository
• Merge the necessary fies from the original homework project into your fork
• commit
• create merge requests for your work

Also use discord for discussing solutions to any issues popping up.
