More on the NO2 ideas discussed on Thursday, July 19 -- Steve Young (SteveYoung) 15:22, 21 July 2007 (EDT) -- Steve Young (SteveYoung) 15:22, 21 July 2007 (EDT)

The goal is to develop a capability that is ready for potential roll-out by late October 2007 and possible announcement(s) at the US EPA Office of Environmental Information (OEI) National Symposium in St. Louis in mid-November 2007 and/or the GEO Summit in Cape Town, South Africa in late November 2007.

Target areas include both the public AirNow ( web site and the AirNow-Tech site, which is more of an extranet environment with user ID/password access:

Our scenario revolves around greater exploitation of NO2 information and includes the better and interoperable use of available data and services from in situ sources and remote sensing, modeling, analytical tools, visualization tools, and perhaps more.

Check KNMI OMI NO2 data at:

That page leads to the near-real-time (NRT) data and the daily archive, showing total column and tropospheric NO2.

Also see:

which leads to monthly OMI NO2 data for North America and also to SCIAMACHY and GOME data.

CMAQ model outputs are also of interest. In particular, note the CMAQ ozone forecast data at:

Creating a Plan -- Glynis Lough (Glynislough) 18:13, 24 July 2007 (EDT)

I'm summarizing our ideas from Thursday's discussion and making a draft plan. Please give me updates on any discussions you have had with others (either on or off the "assigned" followup discussion list).

While NO2 is ripe for short-term action, we should keep in mind that this can be a step towards greater synthesis of many other types of air quality tools, datasets, and models - in both the short and longer terms.

Glynis, exactly right and I'm glad you expressed that point. Most definitely we want this initial effort to be a stepping stone toward more! And we should strive to factor that into our process, that we think about how we can build a stronger foundation for further efforts that need not be limited to NO2. For example, formaldehyde as another target, etc.

We also talked about the importance of establishing context for NO2. I stumbled across this UK site:

While the specific discussion has limitations, it might be a very rough model for the type of explanatory material that would be needed for any public exposure of more NO2 information.

I've spoken to our chief Giovanni architect and we see no problem in having our regridding and/or statistical services available in this timeframe. I'll still need to talk with Greg Leptoukh about making sure there are resources.
