Hermes — Air Quality Intelligence

com.southlondonscientific/hermes

Plugs Claude into the UK's fragmented air quality monitoring landscape with a unified interface. You get live readings from major networks (AURN, LAQN, AQE, SAQN and others), historical trend queries, Local Air Quality Management statistics, and WHO guideline compliance checks. The knowledge base covers regulatory context and intervention evidence. Built by South London Scientific, who run Argus dashboards and the RHEA intervention evaluation tool. Reach for this when you need to answer questions about UK pollution levels, assess exposure scenarios, or build context into environmental health analysis without manually wrangling data from a dozen different borough and national monitoring APIs.
