# Statistics

### Wind Resource Grid

The Wind Resource Grid (WRG) is a spatial, statistical representation of the wind resource in a specified area, including Weibull and Wind Rose parameters. We provide WRG for interoperability of our results and their format with existing software solutions like WindPro, OpenWind and WindFarm.

The WRGs provided with Whiffle Wind Statistics are created from a 180-day LES simulation, following Whiffle's [long-term-representative day selection method](../advanced-topics/long-term-representativeness) in pre-processing. This means they are long-term representative but not bias-corrected w.r.t. to measurements.&#x20;

After the simulation has completed a zip with the WRGs can be downloaded from the application.

### Long-term-corrected results

In case you added one or more Turbines to your simulation, the turbine-level Energy Production will be calculated in the LES and [long-term corrected](../advanced-topics/long-term-representativeness) in post-processing.&#x20;

After the simulation has completed the long-term-corrected Annual Energy Production can be viewed in the Performance Table in the application, or downloaded as CSV.
