Abstract

Key Points:  The HRRR model surface thermodynamic biases are seasonally dependent, presenting a systematic warm and dry bias during the warm season.  The primary locations of the summer warm and dry biases are over farmland, on days with optically thick clouds.  A hydrological bias underestimating of spring snow melt is consistent with subsequent summer warm and dry biases over farmland.
