The Trusted Weather Intelligence Behind Industry Leaders
Why Choose US1k?
The model redefines short-term weather forecasting for the contiguous U.S. and Gulf of Mexico with a horizontal grid resolution of 1 kilometer (~0.62 miles). This granular detail enables the detection of even the most localized atmospheric phenomena, such as isolated thunderstorms, sea breezes, and urban heat islands.
Unlike traditional models, US1k updates hourly using advanced data assimilation techniques, including radar and satellite data, to provide insights with 15-minute time resolution and a forecast range of up to 48 hours.
US1k is designed to augment models like HRRR by offering more comprehensive coverage, better lead times, and higher resolution forecasts.
It combines the best of ECMWF’s global capabilities with robust U.S.-based observational data, creating the most reliable, high-resolution weather model tailored to American industries.
Whether in agriculture, energy, transportation, or emergency management, US1k delivers the actionable insights you need to stay ahead.
Key Features of US1k
- Unmatched Resolution: With a 1-kilometer (~0.62-mile) grid, US1k delivers detailed, localized forecasts, capturing small-scale weather events like heavy downpours, localized flooding, and even potential tornado formation.
- Enhanced Coverage: Covering the entire contiguous U.S. (CONUS) and the Gulf of Mexico, US1k has extended coverage further south than the HRRR model – igniting more value for industries like energy and shipping, along with unprecedented high-resolution hurricane tracking capabilities.
- Frequent Updates: US1k updates hourly, powered by the latest U.S.-based observed data, radar inputs, and satellite imagery. This ensures you’re always working with the most up-to-date insights.
- High-Resolution Downscaling: The US1k utilizes our exclusive data post-processing methods, down to 90 meters (98.4 yards), to provide unparalleled precision for every industry. This technique helps make weather data more detailed and specific. With high-resolution datasets, you get more localized, accurate, and reliable weather information tailored to your needs.
- Comprehensive Parameter Suite: The US1k provides access to over 1,800 weather parameters, encompassing standard metrics like temperature, precipitation, and wind speed, as well as advanced data such as soil conditions, solar power output, wind speed at hub height for wind turbines, cloud properties, and countless more.

A Breakthrough in Weather Forecasting Precision
US1k redefines precision and timeliness in weather forecasting, offering a transformative leap for the contiguous U.S. and Gulf of Mexico.
US1k vs. Traditional Weather Models
Higher Resolution
By enhancing HRRR’s 3-kilometer, ECMWF's 9-kilometer and GFS's 28-kilometer data resolutions to a precise 1-kilometer grid, we deliver highly detailed local weather forecasts, offering critical insights for informed decision-making.
More Extensive Geographical Coverage
Unlike HRRR, US1k extends coverage further south and offers more accurate insights for Gulf regions with its robust 48-hour forecast range, introducing unprecedented high resolution hurricane tracking possibilities.
More Frequent Data Assimilation
While ECMWF processes updates four times daily, US1k integrates hourly radar, weather station data, satellite observations, and aircraft data, ensuring data accuracy in rapidly changing weather conditions.
Graphical Comparison of Weather Models
Below, we compare the spatial resolution of US1k with HRRR, GFS, and ECMWF-IFS. The comparison reveals the superior resolution of US1k, showcasing the finest and most granular weather details across all parameters. It’s like zooming in with a high-powered microscope.
Available Weather Data in the American Weather Model US1k
US1k combines data from diverse sources, including aircraft, ground stations, drones, radars, and satellites, to ensure comprehensive weather coverage.
A streamlined interface delivers access to over 1,800 parameters, spanning general and industry-specific weather variables.
How Does US1k Work?
Boundary Conditions
The accuracy of a weather model depends heavily on its initial conditions, making high-quality input data essential for precise calculations.
Since US1k relies on data from beyond the United States for its boundary conditions, we use the ECMWF-IFS global model, renowned for its exceptional forecast quality. This model's native resolution typically ranges from 9 to 18 kilometers.
Key specifications of ECMWF-IFS:
- Spatial resolution: 0.1° (approximately 9 km)
- Temporal resolution: up to 1 hour
- Forecast lead time: 15 days (with detailed forecasts up to 90 hours at 6 and 18 UTC)
- Frequency of updates: 4 times per day
Downscaling and Calibration
Our model outputs are post-processed through downscaling, refining the 1 km resolution to 90 m by integrating the NASA terrain model into the calculations. This integration provides detailed data on elevation, land cover, and terrain features globally, enabling the model's algorithms to deliver even more accurate forecasts, particularly for mountainous regions and coastlines.
In the final step, we calibrate the model’s data with the most recent observational data, allowing for more frequent adjustments and providing even more refined and up-to-date forecasts.
Rapid Refreshes – Be Ahead of the Market
For energy traders, the next 24 to 48 hours are critical, making detailed weather data indispensable for intraday and day-ahead energy trading. US1k’s rapid refresh cycles and 48-hour lead time provide highly precise short-term forecasts, ensuring traders stay informed with the latest weather insights. As bidding depends on accurate projections of energy production and demand, reliable weather forecasts are key to their decision-making.
Technical Specifications
- Computing Effort: Approximately 40,000 CPUs are needed, across 300 HPC compute nodes.
