1) Meteorological support for real-time andforecasted variables (e.g., wind, precipitation,temperature, etc.)
2) Meteorological support for CAMEO/ALOHA and access to output from a national dispersion model -HYSPLIT (Hybrid Single-Particle Lagrangian- Integrated Trajectory)
5) NOAA Weather Radio – all hazards capability
3) Support from the Scientific Support Coordinator(Great Lakes and Western Rivers)
4) Support from NOAA-Seattle
Meteorological support for real-time and forecast weather elements
Surface observations(wind, temperature, visibility, etc)
A little about concentrationor exposure
The NWS can help with at least two important variablescritical for concentrations/exposure (Wind & Stability)
Relationship between wind and concentration
Wind is inversely proportional to the concentration!-the stronger the wind, the lower the concentration-the weaker the wind, the higher the concentration
Stability – the downwind plume from an event will beextremely dependent on the structure of the temperatureprofile in the vertical (the stability)
Stable atmospherestays very confinedIn the vertical
Unstable atmosphereover stablestays confined abovesurface, but expandsaloft
Very unstable atmospherespreads very widely overthe vertical
Unstable atmospherespreads vertically with time and distance

2) Support for CAMEO and access to HYSPLIT
CAMEO/ALOHA – designed to estimate local impactsand weather conditions do not vary (normally run by local emergency management)-basically near ground-time scale of one hour after event-distance of 10 km downstream
HYSPLIT – designed to estimate long-range transportand dispersion and uses operational weather models as input (normally run by NWS, NOAA)- elevated/ejected releases & large scale diffusion-time scale = several hours to several days-distance = significant distances downstream

Work together on events
Scientific Support Coordinator (Great Lake and Western Rivers) is located in Cleveland and the NOAA – Seattle (NOS HAZMAT office) generally work together if there is an “event”.
-EPA usually gets involved with small chemical spills (events) and NOAA with the large ones.-NOAA will also be brought in on spills/releases on the larger rivers and can support plume dispersion through CAMEO/ALOHA . -Coast Guard for barge or ship releases.
NOAA’s involvement in any particular event generally depends on if the EPA, Coast Guard, or EMA calls them.NOAA/NOS 24 hour operations # = 206-526-4911
