3. Relationship between NWS and FSL

4. Better forecasts of surface conditions require model- based solutions

5. Why run local models? High resolution is a very good thing, but centrally-generated forecasts require high- volume communications. Forecasters are scientifically stimulated. Better forecasts. Duh.

6. Why not run local models? Expensive? Labor-intensive? Unreliable? Unproven?

8. Data sources for LAPS in AWIPS RUC provides first guess Surface: metars, buoys, satellite IR for  T, local obs via LDAD (v4.2) Upper winds: profiler (not ACARS, WSR88D) Clouds: WSR88D reflectivity, satellite IR+vis, metars (not pireps, radiometers) Water vapor: cloud fields + 11.7  (not ACARS, radiometers, GPS)

9. What LAPS is, what it does Hourly 3d analyses of state variables and derived fields Grid positioned with WFO at center (localization) 61x61 gridpoints at 10-km resolution 21 levels in vertical every 50 mb 3d cloud type, % coverage, mixing ratios of cloud liquid, cloud ice, rain, snow, and graupel; also reflectivity Derived sfc fields: CAPE, LI, moisture convergence, etc.
