چکیده

Response: Qi et al. (2017a) has been revised to Qi et al. (2017b). We extended the time period from one month (April) in Qi et al. (2017b) to four months (each representing one season) and extended from the surface BC in Qi et al. (2017b) to the column BC that has implications for radiative forcing. We have highlighted these differences in the sentence as “We extend the application of this method to investigate the seasonal and annual responses of Arctic column BC to changes in regional emissions.”. Kopacz et al. (2011) has been removed because this is a relatively old study and it not directly relevant to this study.

Interactive comment on “Tagged tracer simulations of black carbon in the Arctic: Transport, source contributions, and budget” by

This is an interesting study investigating the source Black Carbon (BC) to the Arctic using GEOS-CHEM, a global chemical transport model (CTM). Ikeda et al. used a tagged tracer method to quantify the contributions of emission source the Arctic BC. The authors also discussed the seasonality of transport pathways of BC to the Arctic. In general, the paper is well-written and easy to follow, and ...

Source attribution and interannual variability of Arctic pollution in spring constrained by aircraft (ARCTAS, ARCPAC) and satellite (AIRS) observations of carbon monoxide

We use aircraft observations of carbon monoxide (CO) from the NASA ARCTAS and NOAA ARCPAC campaigns in April 2008 together with multiyear (2003– 2008) CO satellite data from the AIRS instrument and a global chemical transport model (GEOS-Chem) to better understand the sources, transport, and interannual variability of pollution in the Arctic in spring. Model simulation of the aircraft data give...

Sources of carbonaceous aerosols and deposited black carbon in the Arctic in winter-spring: implications for radiative forcing

We use a global chemical transport model (GEOSChem CTM) to interpret observations of black carbon (BC) and organic aerosol (OA) from the NASA ARCTAS aircraft campaign over the North American Arctic in April 2008, as well as longer-term records in surface air and in snow (2007– 2009). BC emission inventories for North America, Europe, and Asia in the model are tested by comparison with surface a...

Interactive comment on “Constraints on aerosol processes in climate models from vertically-resolved aircraft observations of black carbon” by Z. Kipling et al

This manuscript compares vertical profiles of black carbon (BC) mixing ratios from two global models (HadGEM3-UKCA and ECHAM5-HAM2) with aircraft observations. The models are found to over-estimate black carbon mixing ratios, particularly in the upper troposphere and tropics. Results of two additional sensitivity tests related to biomass burning emissions and convective wet scavenging are prese...

Siberian Arctic black carbon sources constrained by model and observation.

Black carbon (BC) in haze and deposited on snow and ice can have strong effects on the radiative balance of the Arctic. There is a geographic bias in Arctic BC studies toward the Atlantic sector, with lack of observational constraints for the extensive Russian Siberian Arctic, spanning nearly half of the circum-Arctic. Here, 2 y of observations at Tiksi (East Siberian Arctic) establish a strong...
