Backtest

This endpoint provides a backtested energy production anomaly forecast (i.e., what our forecast would have been if queried on a specific day) for a particular latitude/longitude pair or a global forecast. Backtested forecasts are available from 2000 to 2024 on the 1st and 15th day of each month. The anomalies are based on the 1980-2010 baseline, with solar and wind power expressed as fractional units. Degree Days are output in HDDs/CDDs per day. Note that this endpoint does not include observed values.
