Local Climate Analysis Tool (LCAT)

Created: 7/31/2017 - Updated: 2/27/2020


The Local Climate Analysis Tool (LCAT) allows users to explore local climate variability in relation to global climate trends and to investigate the linkages between local climate, weather, and water events. Intended to enhance local climate expertise of National Weather Service (NWS) staff, LCAT analyzes available climate data sets (provided and recommended by NOAA) via the NWS Virtual Lab platform, helping users conduct local climate or correlation studies through a scientifically credible process. LCAT also provides avenues for scientific discussion and idea exchange; it allows users to query available studies, interact with other users, and upload study results for review and publication purposes. LCAT facilitates decision support in the realm of climate questions, and can be used as guidance in generating local climate studies and/or products. As an internal NOAA tool, LCAT is currently available for all NOAA users; non-NOAA users may use LCAT, but must have a NOAA-sponsored partner apply on their behalf to gain access to this tool.

NOAA is an agency that enriches life through science. Our reach goes from the surface of the sun to the depths of the ocean floor as we work to keep citizens informed of the changing environment around them. From daily weather forecasts, severe storm warnings and climate monitoring to fisheries management, coastal restoration and supporting marine commerce, NOAA’s products and services support economic vitality and affect more than one-third of America’s gross domestic product.

The National Weather Service is a component of the National Oceanic and Atmospheric Administration (NOAA). NOAA is an Operating Unit of the U.S. Department of Commerce.

Our Mission Provide weather, water, and climate data, forecasts and warnings for the protection of life and property and enhancement of the national economy.
