CW100: Hyperlocal forecasting at up to 100 meter resolution
CW100 is a proven weather forecasting model capable of predicting actionable, near-surface winds and temperatures with unprecedented 100 meter resolution and accuracy. CW100 captures the microphysics on a fine scale near the surface, accounting for microclimates, topography and even vegetation.
More intelligent than pure AI: a completely dynamic system that incorporates AI input and exceeds typical AI capabilities by identifying AI model biases and incorporating human reasoning.
“Model of Models” Numerous exisiting models are incorporated into a “Master” model. This allows changes to occur on a micro-scale.
Human Meterologist Reasoning: Meteorologists can quickly add additional logic based on local expertise that cannot be replicated by AI forecasts.
Supports ALL sensor data: LiDAR, UAV weather reports, soundings, aircraft weather reports, RADAR, wind profilers, etc.
Overcomes AI limitations in near-surface microscale forecasting: AI microscale forecasting is weak due to lack of historical data. CW100 excels in this area.
The CustomWeather CW100 Model is based on physics, not statistics or airport observations. As a result, it can achieve significantly better accuracy than statistical models, especially for non-airport locations. The CW100 Model is able to resolve additional physical processes near the ground that are not resolved by other models and is able to operate at a much higher resolution, typically 100x finer than standard models and other gridded forecasts.
- Excellent performance for both daytime and nighttime forecasting.
- Lightweight: high speed, low cost — can easily be run on a single computer
- High resolution: 100 meters or less
- Accurate land surface properties
- Realistic near-surface physics
- Works everywhere, not limited to observation sites
- Very accurate near the ground – consistently beats NWP, NWS MOS, and most human forecasters
- CW100 is not limited to observation sites (airports) or population centers because it relies on gridded data sets that are primarily satellite-derived.
Update Frequency:
CW100 data is typically produced in 1-hour increments although 15-minute increments are also possible.
CW100 Model outputs include:
- air temperature (dry bulb)
- minimum air temperature (dry bulb)
- maximum air temperature (dry bulb)
- dewpoint temperature (wet bulb)
- wind speed
- wind gust speed
- wind direction
- soil temperature
- net radiation
- precipitation rate
- cloud area fraction
