Quantifying uncertainty in Daymet

Daymet cross-validation tile-wide summary statistics for maximum temperature in 1980; "daymae" = mean absolute error for single day predictions.

Daymet: Annual 2-degree Tile Summary Cross-Validation Statistics for North America

This data set provides annual summary cross-validation statistics for minimum temperature (tmin), maximum temperature (tmax), and daily total precipitation (prcp) of "Daymet: Daily Surface Weather Data on a 1-km Grid for North America, Version 2" (Thornton et al., 2014). These statistics represent the uncertainty in the Daymet temperature and precipitation estimates. Cross-validation statistics were generated by the Daymet model algorithm from the station-based daily observations and predictions and are summarized for each of the 2-degree by 2-degree tiles for which Daymet is derived. Data are available for the time period 1980 through 2014, the most recently processed calendar year of Daymet Version 2.
