PM2.5 Open Data Portal (LASS)
pm25.lass-net.org
The LASS participatory PM2.5 sensing network run by IIS-NRL, Academia Sinica: latest readings per project, calibrated PM2.5 per monitoring site, and the anomaly detection framework's device rankings, emission estimates, indoor/outdoor classification and pollution events.
The crw MCP on your computer calls PM2.5 Open Data Portal (LASS) directly. Calls cost no credits and the data does not pass through fastCRW. Install it once for Claude Code, Cursor, Codex, Windsurf, Gemini CLI or OpenCode, with your fastCRW API key in place of the placeholder:
Ask with this source
A prompt for your agent that names this source and how to call it through the crw MCP.
Anomaly ranking for one device
Use PM2.5 Open Data Portal (LASS) (pm25) from fastCRW Pergamon, capability "Anomaly ranking for one device" (adf-device-ranking). You hold a device id and want its anomaly score rather than the whole ranking table. Example options: device_id=AirU_F45EABA254AA. Use the crw MCP tools: crw_find_data to confirm the source and its options, then crw_get_data with provider "pm25" and capability "adf-device-ranking". Tell me the credits used and cite the licence from the response. If the crw MCP tools are missing, install them with: npx -y crw-mcp install --api-key <your fastCRW API key>
Device emission estimate
Use PM2.5 Open Data Portal (LASS) (pm25) from fastCRW Pergamon, capability "Device emission estimate" (adf-emission). You are estimating how much a source device contributes to local PM2.5. Use the crw MCP tools: crw_find_data to confirm the source and its options, then crw_get_data with provider "pm25" and capability "adf-emission". Tell me the credits used and cite the licence from the response. If the crw MCP tools are missing, install them with: npx -y crw-mcp install --api-key <your fastCRW API key>
Indoor/outdoor classification
Use PM2.5 Open Data Portal (LASS) (pm25) from fastCRW Pergamon, capability "Indoor/outdoor classification" (adf-indoor). You need to separate indoor sensors from outdoor ones before comparing readings. Use the crw MCP tools: crw_find_data to confirm the source and its options, then crw_get_data with provider "pm25" and capability "adf-indoor". Tell me the credits used and cite the licence from the response. If the crw MCP tools are missing, install them with: npx -y crw-mcp install --api-key <your fastCRW API key>
Pollution event classification
Use PM2.5 Open Data Portal (LASS) (pm25) from fastCRW Pergamon, capability "Pollution event classification" (adf-pollution). You want events already labelled by pollution type rather than raw concentrations. Use the crw MCP tools: crw_find_data to confirm the source and its options, then crw_get_data with provider "pm25" and capability "adf-pollution". Tell me the credits used and cite the licence from the response. If the crw MCP tools are missing, install them with: npx -y crw-mcp install --api-key <your fastCRW API key>
