# What are these Gizmos at Mauna Loa Observatory?

(Asked by: username_0 on 2019-03-15)

Artist Rosten Wu's Vimeo channel has a video title [Bridging Time](https://vimeo.com/315754123) and there is discussion about the [Keeling Curve](https://en.wikipedia.org/wiki/Keeling_Curve) and the site where it all began in Hawaii.

In the video there is a shot of a weather observation station (shown below), and I'm assuming this is [Mauna Loa Observatory](https://en.wikipedia.org/wiki/Mauna_Loa_Observatory) where these accurate and systematic measurements of CO2 began.

In the foreground there are several gizmos and I was wondering if someone can identify them.

I've included a cropped section, sharpened it a bit, and added annotations A, B, C *below* the three types of instruments that caught my eye.
