Housed inside a **matte black sphere**, this sensor captures the combined effects of ambient air temperature, solar radiation, and wind. The resulting data enables accurate WBGT calculations, which are essential for evaluating heat stress risk in outdoor environments. This information supports public health and safety initiatives by providing reliable, real-time monitoring for robust environmental assessment. The Black Globe can be installed in lieu of the light sensor. ### Instruction Slides for Assembling the Black Globe {% embed url="" %} --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://3dpaws.comet.ucar.edu/building-3d-paws/adding-additional-instruments/black-globe.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
