Results:
Moderate downhill negative linear correlation between albedo and temperature in the core of icefield “R2=-0.57”, (where correlation should have strong relationship and the slope of linear regression for albedo and temperature in the core of icefield) represents that albedo reduction correlated with another parameter. Figures 9 shows demonstrate reduction and increment of albedo after wildfires that soot and smokes come to study area on 2016 that had the highest albedo anomaly in time series. After wildfires that located at the distance of 300 kilometers from study area also wildfire area was higher than 100 hectares, snow albedo reduction occurred.

Conclusions:
The research question for the project is: which one (land surface temperature or wildfire soot) plays a significant role in albedo change in time series on Columbia icefield? Although, in this research, surface albedo and surface temperature have negative correlation but wildfire soot`s has significant role in in albedo reduction. ( Figure 11 ). External entities effect on ice/snow energy balance are not considered. The results of this project will be used in the integrated modelling for ice/snow energy and mass balance.
We have investigate the effect of wildfire soot, which is correlated with the snow albedo reduction over the Columbia icefield in summertime (Jun,July and August) from 2000 to 2016. Remote sensing data used in the study, which is included land surface albedo and land surface temperature, were obtained from the MODIS, Terra satellite. We have used hysplit back trajectory analyses for 2000-2016 (Monthly) to investigate the airflow that comes to Columbia.
