What is the impact of Light Absorbing Aerosol over
Greenland?

events of the Greenland Ice Sheet"

"Contribution of light-absorbing impurities in snow to Greenland’s
darkening since 2009"

Aerosols and the Cryosphere – Greenland Example.
What is the impact of Light Absorbing Aerosol over
Greenland?
"Large uncertainties and lack of knowledge of Light Absorbing
Impurities (LAI) effect on snow albedo and snow melt."

Modeling hydrologic response to aerosols.
Motivation
Catchment discharge can be used
as integrated observation when
simulating the effect of LAI on the
snow albedo and snow melt.

We use a model chain to simulate
the effect on albedo and snow melt:

Summary and Outlook
Results
We have developed a new model that incorporates aerosol deposition
into an online hydrologic model
... even with low BC deposition in Norway there is an effect ...
... robust evaluation against two transport models ...
... sensativity studies to model paramaters ...
We have conducted climate simulations and demonstrated large
potential BC forcings over HKKH region ... next steps are to couple
the hydrologic model to the climate model output ...

Summary and Outlook
Outlook
Significant potential for large impacts from BC deposition over
Himalaya.
... large increases in Top of Atmosphere (TOA) forcing ...
... positive feedback to enhanced melting ...
... shift in timing of runoff ...
... implications for water balance ...
