Building Predictive Models? Check out these apples!
The ongoing forecast files are built on the same downscaling technology used for generating the historical data – your predictive models are comparing apples to apples! You can even set up notifications for important weather model upgrades or changes!
We know and understand that changes in weather models can affect your results. We have your back and will provide you with notification of changes!

Point
Observations
Point data can be from observation stations or derived reanalysis values for customer defined points. Data can be combined within a region for single point values such as: zip or postal code level.

High Resolution Gridded Output
Grids can include standard model grids or custom grids based on the customer requirement. Grids are currently available down to 1km resolution.
​

Ongoing Tuned Forecasts in Consistent Formats
Ongoing forecasts will be available for the same points/grids using the same downscaling technology. We can integrate customer observations for additional tuning and MOS bias correction.
