Combining LowCost Sensors and Reference Networks for ...

· For the low cost sensor data we are not currently distributing these as they come from Purple Air. However this is a request we have heard and will try to address in some fashion after the deployment of the revised map this summer. At the least we should have codebase that will be shared that can be applied to data retrieved from Purple Air’s own data archives.
