Insurance and Reinsurance

View Products  View Storymaps View NOAA Resources

Leveraging the National Centers for Environmental Information’s (NCEI) environmental data improves risk modeling and analysis for the insurance sector, supporting faster recovery from extreme events and informing decision making surrounding insurance pricing and individual risk.

NOAA data validates property insurance claims across the country. Insurance and reinsurance companies need this data to be easily accessible and high-quality to protect the lives, livelihoods, and assets of millions of Americans. While insurance companies help protect individuals and businesses from loss, reinsurance companies help protect insurers from loss and ensure their financial solvency, so they can continue to offer coverage and pay out claims.

The insurance and reinsurance industry provides vital financial support for communities recovering from extreme weather events. These events have a significant economic impact: from 2017 to 2024, there were over $1 trillion in total direct losses from extreme weather and climate events in the United States. The industry is valued at billions of dollars each year, making it one of the largest industries in the U.S., significantly contributing to the nation's GDP. However, with the increase in extreme weather events, insurers are facing challenges at an unprecedented scale and require new and improved methods to identify and manage their climate risk.

Building on years of previous engagement, NOAA has partnered with the Reinsurance Association of America (RAA) to better understand the climate and weather information needs of the industry and help inform day-to-day decision making and operations, ensuring industry resiliency in the coming decades.

Our Goal

By providing access to the most accurate and up-to-date environmental information and tailored data and products, NCEI is supporting insurers’ efforts to improve their catastrophe modeling and analysis to inform pricing, evaluate claims, and support rapid recovery in communities after extreme weather events.


Data-Driven Impacts for Insurance and Reinsurance

Insurance and reinsurance companies need accessible, downscaled, and contextualized climate and weather information to better understand and mitigate risk and inform their catastrophe models.

Insurance companies price their premiums using computer models called catastrophe models–simulations that develop estimates based on the cost of potential disasters. As the number of extreme weather events increases year over year and the frequency of disasters totaling $1 billion or more has been rising, catastrophe models need to account for this change by incorporating the most accurate and up-to-date weather, climate, and population data.

Through regular working group meetings and other industry discussions, users have shared the following areas where they need additional data and products to understand how risk is evolving and support informed decision-making and operations:

A new Event Catalog with interactive spatial maps to define the physical impact areas of current and future evolving weather and climate hazards in the U.S. to better understand financial risk.

An updated Storm Events Database product with interactive maps, event-specific details, and automated reporting to aid in assessing risk to regions, evaluating trends over time, and expediting the validation of insurance claims.

Climatologies (climate studies that summarize long-term weather patterns, averages, and trends in a region) of hail and wind, including information on derechos and straight-line winds and their geographic footprint, to help process claims.

Through NOAA products and services, the insurance and reinsurance sector will be equipped with the data and tools needed to improve their catastrophe modeling and risk evaluation. A more accurate catastrophe model enables insurance companies to quickly assess and process damage claims following a disaster, supporting rapid recovery in communities. Better informed models also help understand future weather and climate risk, and ensure that individuals and businesses are properly protected before an event occurs.

ADT-HURSAT

ADT-HURSAT

Period of record: 1979 - 2024, static

This product applies the Automated Dvorak Technique (ADT) from the Cooperative Institute for Meteorological Satellite Studies (CIMSS) to the HURSAT dataset, producing a consistent record of storm intensity estimates. The interface will include the dataset and will have direct download functionality, Python notebooks to aid users in the data download process, and simple use case examples within the notebook for insurers to integrate into hurricane risk analysis and preparedness. This update is expected by winter 2025-26.

Billion Dollar Weather and Climate Disasters (BDD)

Billion Dollar Weather and Climate Disasters (BDD)

Period of record: 19802024

The BDD aids the insurance and reinsurance industry in risk mapping and is responsible for tracking 400 historical weather and climate events totalling $2.785 trillion in damages. By combining extreme weather and economic data, this product quantifies previous national disasters and provides risk metrics based on disaster exposure. The data covers hazards like droughts, floods, hurricanes, and wildfires.

Climate Atlas

Climate Atlas

Period of record: 1895 - Present

NCEI is updating U.S. Climate Atlas, where users will have access to a collection of interactive and customizable temperature and precipitation climatology maps. NCEI is adding threshold maps, such as the number of days in a year over/under a certain temperature, and maps on various events, such as the first frost date or the hottest day of the year. Included datasets will be updated on an ongoing monthly basis. Insurers and reinsurers can utilize this collection of temperature, precipitation, and degree-day maps to better understand long-term weather trends. This update is scheduled for the fall of 2026.

Event Footprint Catalog

Event Footprint Catalog

Period of record: 2010 - Present

This tool will map the geographic footprints of high-impact weather events. Featuring an interactive map, the catalog will include a searchable index of historical weather events such as severe convective storms, including tornadoes, hail, and severe wind events. Users will define the area of interest for mapped weather event impact footprints and will be able to download map layers with event details. This will help insurers assess risks, plan responses to upcoming weather events, and characterize past high-impact events. The first phase of the product will focus on severe convective hazards and is expected by late summer 2026.

International Best Track Archive for Climate Stewardship (IBTrACS)

International Best Track Archive for Climate Stewardship (IBTrACS)

Period of record: 1842 - Present

By combining recent and historical global tropical cyclone data, IBTrACS creates a comprehensive collection of tropical cyclone (hurricane) tracks, allowing insurers and reinsurers to inform their catastrophe models, visualize regional trends, and assess how risks are evolving over space and time. NCEI is revising the back-end code that manages this data to meet modern coding standards. This update is scheduled for release in the summer of 2026.

Storm Events Database (SED)

Storm Events Database (SED)

Period of record: 1950 - Present* 75 day delay

The SED offers access to National Weather Service Storm Data, which documents over 55 types of storm events and other significant weather phenomena. To support communities recovering from extreme weather events, SED helps insurers assess risk to regions, evaluate trends over time, and validate insurance claims more quickly. NCEI updated the SED in 2025 to include interactive maps, event-specific details and photos, and automated PDF generation. To better meet user needs, NCEI created a pathway to easily certify storm events on the custom PDFs. This update was released in the summer of 2025.
