A new physically based parameterisation of black carbon (BC) in snow wasdeveloped and implemented in the Canadian Atmospheric Global Climate Model(CanAM4.2). Simulated BC snow mixing ratios and BC snow radiative forcingsare in good agreement with measurements and results from other models.Simulations with the improved model yield considerable trends in regional BCconcentrations in snow and BC snow radiative forcings during the time periodfrom 1950–1959 to 2000–2009. Increases in radiative forcings for Asiaand decreases for Europe and North America are found to be associated withchanges in BC emissions. Additional sensitivity simulations were performed inorder to study the impact of BC emission changes between 1950–1959 and2000–2009 on surface albedo, snow cover fraction, and surface airtemperature. Results from these simulations indicate that impacts of BCemission changes on snow albedos between these 2 decades are small and notsignificant. Overall, changes in BC concentrations in snow have much smallerimpacts on the cryosphere than the net warming surface air temperaturesduring the second half of the 20th century
