Air Quality Data Network (ADN): Context and Scope (Non-IT Issues)

These are all potentially contentious topics, so can only be touched upon but discussed in detail.

What is the purpose of ADN?

Who are the participating users of the network? What are their roles?

What organizations are stakeholders in the network? How do they relate to ADN?

What is the ADN governance, legitimacy, impediments

What are the minimum requirements for ADN?

What few things must be the same, so everything els can be different. Autonomy - Interoperability balance...

What is the scope of AQN?

Geographic, Variables, Ambient fixed station observations, satellite observations, emissions, models?

What data (processing) level served through ADN?

Is ADN a decider? Why not the Provider? Data Raw, Derived;

Data Servers: Technical Realization (IT) Issues and Solutions

Issues re. the use of netCDF

netCDF is standard format for multi-dimensional data. Cf-netCDF is used both as an archival format of grid data as well as a payload format for WCS queries. Issues: Python interface issue/question here ...in about one sentence

WCS versions

WCS is implemented in multiple versions: 1.0, 1.12, 2.0. The AQ Community Server (AComServ) is now implemented using WCS 1.1.2. Define here the WCS version (WCS 2.0) issue in about one sentence

Use of WMS, WCS, WFS .. in combination?

Data display is through WMS. AQ data can be delivered through WCS, WFS. In AComServ, WCS for transferring ndim grid and point-station data; WFS for deliver monitoring station descriptions. [Define here issues related to this choice

Gridded data service through WCS

This is a loaded questions…how to tackle it?

Station-point data through WCS

This is a loaded questions…how to tackle it?

Data server performance issues/solutions?

Define performance issues, measurements

Server co-development tools, methods

incl maintenance, version control, Documentation

Relationship to non-AComServ WCS servers

Data Network: Technical Realization (IT) Issues and Solutions

What is the design philosophy

Service oriented (everything is a service), Component and network design for change; open source (everything?!)

Functionality of an Air Quality Data Network Catalog (ADNC)?

Content and structure (granularity) of ADNC?

Interoperability of ADNC

Interoperability with whom? what standards are needed? CF Naming extensions? ===
