Introduction:

The Local Analysis and Prediction Branch performs high resolution analyses and forecasts of the weather using both locally and centrally available meteorological observations. The LAPB Branch is a component of NOAA's Forecast Systems Laboratory.

The Local Analysis and Prediction System (LAPS) integrates data from virtually every meteorological observation system into a very high-resolution gridded framework centered on a forecast office's domain of responsibility. Thus, the data from local mesonetworks of surface observing systems, Doppler radars, satellites, wind and temperature (RASS) profilers (404 and boundary-layer 915 MHz), radiometric profilers, as well as aircraft are incorporated every hour into a three-dimensional grid covering a 1040km by 1240km area. LAPS has analysis and prediction components. The prediction component is being configured using the RAMS, MM5, WRF, and ETA models. Any or all of these models, usually being initialized with LAPS analyses, are 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 is run in real-time at FSL for a domain centered on the Denver, CO Weather Forecast Office. Local implementations include our branch machine (toro) and the AWIPS/ WFO-Advanced workstation. Analysis and forecast output is often shown at the daily weather briefings. LAPS is an integral part of the Water In All Phases (WIAP) project and is being used in support of the recent IHOP experiment.

LAPS has been ported to many locations, including universities such as Univ. of Oklahoma ("OLAPS"), and Univ. of North Dakota. LAPS is running on-site at each National Weather Service Forecast Office (WFO) as an integral part of AWIPS. We are also running the system externally to AWIPS at WFOs in Seattle, Atlanta (Olympics), Lubbock, Fairbanks, Sterling, Monterey, Reno, and Davenport. Our software is also being implemented at various U.S. government agencies such as Federal Highways Administration (MDSS), Range Standardization and Automation (RSA) at the U.S. Space Centers, National Ocean Service, U.S Forest Service, and for international government weather bureaus such as China, Italy, Taiwan, Thailand, and Korea.

LAPS Software:

LAPS Analysis software may be downloaded in the form of a "gzipped" tar file, available to our list of users. Users may also obtain a Colorado test data case to check how well your implementation of the code is running. We have posted our most recent LAPS release from 8/23/2004. Hints on how to install and run LAPS Analysis software are contained in the README file.
