2010 LAPS Workshop - View Presentations
The data from local meso-networks of surface observing systems, Doppler radars, satellites (radiance and high-resolution imager), wind and temperature (RASS) profilers, radiometric profilers, as well as aircraft are typically incorporated every hour into a three-dimensional grid covering a 1040km by 1240km area. LAPS has analysis and prediction components. The analysis component has two options, "traditional" and variational. A numerical forecast model initialized with LAPS analyses is run to provide short-term forecasts. We produce ensemble forecasts using multiple models and initialization methods, with verification. We have several online LAPS presentations.

LAPS has been ported to many locations, including academic institutions such as Univ. of Oklahoma ("OLAPS"), Univ. of North Dakota, and Univ. of Hawaii's Mauna Kea Weather Center. LAPS is running on-site at each National Weather Service Forecast Office (WFO) as an integral part of AWIPS (the main computer system that weather forecasters use). We are also running the system externally to AWIPS at WFOs in Miami, Lubbock, Fairbanks, Sterling, Monterey, Reno, and Davenport. Our software is being ported and/or being run at ESRL to support various US government agencies such as Atlantic Oceanographic and Meterological Laboratory, Range Standardization and Automation (RSA) at the U.S. Space Centers, National Ocean Service, U.S. Forest Service, as well as state and local government agencies like the California Dept. of Water Resources. We are working in support of renewable energy in the areas of wind and solar power.
We also work with international government weather agencies in countries such as China, where the Institute of Heavy Rain has installed LAPS in fourteen Chinese meteorological centers. Other agencies using LAPS are located in Italy (CNR-ISAC), Taiwan, Korea, Spain (METEOCAT), Finland (FMI), and Serbia.
