Short summary
 This study demonstrates that snow cover generally suppresses crop growth (GPP) in Northeast China's croplands through thermal effects.  Snow cover generally exerts a negative effect on GPP through the thermal influence. Regionally, snow indirectly inhibits GPP via water-mediated effects in the Liaohe and Songnen Plains, but promotes it in the Sanjiang Plain, Xing'an and Changbai Mountains, and Western Sandy Area.
