### 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`

It makes simulataneous measurements of reflected solar radation at 9 widely spaced angles in 4 spectral bands in the blue, green, red and near-infrared. By making measurements at various angles the instrument provides improved discrimination of various aerosol types, cloud and surface features.",
