The NOAA SWPC has primary responsibility for the civilian communities' operational space weather products and forecasting services. Murtagh noted that NOAA SWPC provides multiple watches, warnings, alerts, and summaries to inform the user communities.

It was also clear from Keyser's presentation that many of the products were useful for now-casting, rather than forecasting, space weather events. To date, physical models are not routinely used, but AFWA is making progress on space environment models (see the section titled "Space Weather Models and Tools" below)

When it comes to providing space weather services there is a cross-national perspective. In general the cross-national activities focus on the front-end services, i.e., the services that take data from sensors and deliver products, according to Hapgood.

SOURCE: Michael Hapgood, STFC Rutherford 4.6 Hapgood.eps Appleton Laboratory, "Current Space Weather Services Infrastructure in Europe," presentation to the space weather workshop, May 22, 2008. offers a way of federating a significant number of space weather services around Europe, between 25 and 30 at the moment.

Examples of the types of models being developed are the exospheric solar wind model and a plasmapause location model. Both of these models provide proxies for observables that would be used by higher-level models that generate specific space weather products.

Planned DOD investments in models, applications, graphics, data fusion, and decision aids will improve operational space weather support. In Europe, space weather services are being coordinated and made available through the community-wide European Space Weather Portal noted above (see Figure 4.7 and its associated website address)

to further decrease the time between the collection of data and their availability to users. NOAA SWPC also provides near-real-time space weather data and products from its website (http://www.swpc.noaa.gov/ Data/index.html#alerts)

But, he noted, SWPC has to be very careful that it does not cross into the area where commercial service providers take the opportunity to fine-tune some of the data and products provided by SPWC, an example being space weather services tailored for the power grid industry: even though SWPC can specify the space weather environment, an outside commercial service provider will provide information on the likelihood of a geomagnetically induced current. Keyser noted that for some time the DOD has been creating impact-based products for customers like the Space Command, adding that it is the impacts that the operator flying the satellite or reading the radar screens cares about.

The space weather infrastructure cannot function without the continual stream of space weather data collected by various assets on the ground and in space. Although NASA currently provides much of the raw data from its research satellites, William Murtagh and Herbert Keyser said that they foresee potential gaps in space weather coverage because of inadequate plans for deploying new and dedicated systems.
