ESRL Global Systems Division


The Local Analysis and Prediction System (LAPS) has been developed by FAB for the purpose of data assimilation, nowcasting, and model initialization. It has a wide variety of (~150) group and individual users. This includes federal and state agencies (e.g. NWS, USAF), private sector, academia (e.g. Univ of HI), and international (e.g. Taiwan CWB). LAPS blends a wide variety of global, national, and local datasets (e.g. METARs and mesonets) into analyzed grids. LAPS analyses are used to initialize mesoscale forecast models (e.g. WRF, MM5, RAMS). It utilizes large-scale numerical weather prediction models as backgrounds for both analyses and prediction, and has adjustable horizontal, vertical, and temporal resolution. LAPS is highly portable and runs on inexpensive hardware - desktop to laptop.

The Forecast Applications Branch at NOAA's Earth System Research Laboratory is pleased to announce the first (inaugural) LAPS Users Workshop to be held at ESRL in Boulder, Colorado from October 25-27th, 2010, starting at 1 p.m. Monday through 5 p.m. Wednesday. Informal follow on discussions and training (optional) took place Thursday & Friday October 28-29.

Objective of Workshop:

The purpose of the workshop is to engage the user community in current and future development of LAPS. In particular, the workshop will review recent upgrades and future plans regarding LAPS data assimilation, nowcasting and short term forecasting, information technology, and user applications / products. Presentations by users will be featured. In addition the workshop will offer LAPS training opportunities.
