# Directory Structure

The data processing pipeline transmits data from origination sites to a controlled directory structure on the [ROGER](https://wiki.ncsa.illinois.edu/display/ROGER/ROGER+System+Information) CyberGIS supercomputer.

The data is generally structured as follows:

```
/sites
  /ua-mac
    /raw_data
      /sensor1
        /timestamp
          /dataset
      /sensor2
      ...
    /Level_1
      /extractor1_outputs
      /extractor2_outputs
      ...
  /danforth
    /raw_data
      /sensor3
      ...
    /Level_1
      /extractor3_outputs
```

...where raw outputs from sensors per site are stored in a `raw_data` subdirectory and corresponding outputs from different extractor algorithms are stored in `Level_1` (and eventually `Level_2`, etc) subdirectories.

When possible, sensor directories will be divided into days and then into individual datasets.

This directory structure is visible when accessing data via the Globus interface.

# Agent Instructions: Querying This Documentation

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://docs.terraref.org/revisions/technical-documentation/directory-structure.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
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.
