| findable | 3 | When I tried to search for pollutant emissions in Rio de Janeiro I couldn't find it, but because of the experience filling the national survey, I knew that if I searched for "air quality" I would find it more easily. |
| findable_steps | 1) I looked at google for "Air Quality Rio de Janeiro", 2) I found the link for the MonitorAr project; 3) I checked with a specialist to see if that was the best source. | |

| usability | 1 | Some effort is necessary to understand the specifics of this kind of data. You also need to copy and paste the information in a machine-readable format in order to further work with this data. So I consider it very difficult to use data, even though it is available everyday for consultation. |
| collector_name | SMAC/RJ - Secretaria Municipal de Meio Ambiente da Prefeitura da Cidade do Rio de Janeiro | Data is provided by a project called "MonitorAr-Rio", an agreement between the City Hall of Rio de Janeiro, through its Environment Secretariat with the Federal University of Rio de Janeiro and Petrobras, the brazilian state-owned petroleum company. Data can be obtained through the Environment Secretariat (SMAC) link. |

There are nine in the city of Rio de Janeiro, eight fixed and one mobile. The mobile one had no data due to temporary relocation. |
