Get a list of Instrument objects. Instruments have a 1:1 mapping with Observations.

### Available end points:

- `/instruments/` - Will list all Instruments in the database
- `/instruments.json` - Will return all Instruments in json format
- `/instruments/<object_id>/` - Returns Instruments object with that id

### Available Methods:

- `GET`
- `HEAD`

### Available filters:

- `title`
- `uuid`
- `keywords`
- `instrumentType`

### How to use filters:

- `/instruments/?title__startwith!=Instrument.title: DETAILS NEEDED`
- `/instruments/?uuid=c7fa005e2095425392b18adbd7b40617`
- `/instruments.json?instrumentType=radiometer`

Ozone profiles, atmospheric temperature, concentrations of water vapor and deuterated water vapor, carbon monoxide and methane, nitric acid, effective cloud pressure and optical depth, surface temperature and land emissivity are all derived from TES radiance spectra.",
