The Environmental Content Server publishes automated analysis reports from the envirocontentgenerator pipeline.

Each report is generated from a mobile sensor deployment and includes:

Time-series charts for particulate matter (PM1 / PM2.5 / PM10), ammonia (NH₃), and noise
An interactive route and hotspot map
Policy commentary from the Environmental Policy Advisor, benchmarked against UK air quality regulations and WHO guidelines

Reports are created by running scripts/sync_report.py against a generator output directory.
