<abstract>
<p>In this study, we focus on the latest NASA GISS composition-climate
  model to evaluate its performance in simulating the spatial
  distribution of snow BC (sBC) in the Arctic relative to present
  observations. The radiative forcing due to BC deposition to the
  Arctic snow and sea ice is also estimated. Two sets of model
  simulations have been done in the analysis, where meteorology is
  linearly relaxed towards National Centers for Environmental
  Prediction (NCEP) and towards NASA Modern Era Reanalysis for
  Research and Applications (MERRA) reanalyses. Results indicate that
  both of the modeled sBC are in good agreement with present-day
  observations in and around the Arctic Ocean, except for
  underestimation at a few sites in the Russian Arctic.
 The overall ratio of observed to modeled sBC is 1.1.
  The
  result from the NCEP run is slightly better than that from
  the MERRA run.  This suggests that the latest GISS-E2-PUCCINI model does not
  have significant biases in its simulated spatial distribution of BC
  deposition to the Arctic, and underestimation of biomass burning
  emissions in Northern Eurasia is preliminarily considered to be the
  main cause of the simulation biases in the Russian Arctic. The
  combination of observations and modeling provides a comprehensive
  distribution of sBC over the Arctic. On the basis of this distribution,
  we estimate the decrease in snow and sea ice albedo and the resulting
  radiative forcing. It is concluded that the averaged decrease in
  snow and sea ice albedo in and around the Arctic Ocean
  (66–90&amp;deg; N) due to BC deposition is
  0.4–0.6% from spring 2007–2009, leading to regional
  surface radiative forcings of 0.7 W m&lt;sup&gt;&amp;minus;2&lt;/sup&gt;,
  1.1 W m&lt;sup&gt;&amp;minus;2&lt;/sup&gt; and 1.0 W m&lt;sup&gt;&amp;minus;2&lt;/sup&gt;, respectively in
  spring 2007, 2008 and 2009.</p>
