1. LAPS / STMAS Niche
Highly Portable System, Easy to Use – Many Collaborators/users World Wide
Federal/State Gov’t, International, Academia, Private Sector
NWS/AWIPS, GTAS, FAA/COSPA, RSA, PADS, CWB Taiwan
Wide variety
of data sources:
High Resolution (500m – 20km), Rapid Update (10-60min), Local to Global:
1km analysis, 15min frequency, minute latency
Versus 60min frequency / ~60-90min latency for other hi-res analysis systems (e.g. RTMA) 1

6. Space and Time Multiscale Analysis System (STMAS)
It is a variational multiscale analysis system, a generalization of LAPS;
It provides a better balanced, temporal consistent and improved analysis and forecast;
Its research is supported by various projects but it needs support for transition to operation for improving LAPS analysis and forecast for AWIPS.

9. Financial Support for Transition
LAPS: Resources to support current AWIPS-II transition. Include more data sources and improve spatial / temporal resolution.
STMAS: Additional resource needed for transition, more computation, temporal consistency data source and calibration of the variational analysis for nowcasting and forecasts.
