A series of "virtual workshops" are being organized in order to help the air quality community establish best practices and conventions for implementing data format and exchange standards (e.g., netCDF-CF and OGC WCS)in order to advance the level of interoperability among air quality information systems and projects.

The objectives of the virtual workshops are to

  • publish and expose existing services from multiple providers,
  • compare standards implementations, explore differences, address challenges and reconcile differences in implementations
  • agree on 'AQ Community' conventions and define guidance that harmonize the implementation of standards-based services

The concept of the virtual workshops is to foster interaction among the air quality community through semi-formal workshops that take advantage of remote meeting technologies and allow productive exchanges among the participants while residing in distributed physical locations.

Data being served
Data formats used
Types of web services implemented
  • REST services: xml, csv, kml, json, netCDF
  • OGC WCS for point data, returns AQI surrogate data
  • OGC WCS for point, time-point, and grid
Access to web services

include access points such as GetCapabilities or example data access requests (e.g., GetCoverage)

Issues and questions
  • web services require authentication (using API key)
  • payload options and formats (netCDF is evolving)
  • need to make things uniform
