'Comment on egusphere-2023-1431', Anonymous Referee #1, 01 Sep 2023

It is a very interesting article and an alert for future impacts from global warming that will certainly contribute to HCHO emissions.
However I am not familiar with the methodology used to acquire data.
Abstract must contain quantitative results.
Lines 30-32 could use traditional references for HCHO formation, as those from Atkinson, Seinfeld, Pitts and Carter.
I t is not possible to use other molecules as wildfires tracers as carbon monoxide, and other type of molecules to help to understand the results as COS?
The results can be extrapolated to South Pole ?

Short summary

HCHO variability is a key tracer in understanding VOC emissions in response to climate change. We investigate the role of methane oxidation and biogenic and wildfire emissions in HCHO interannual variability over northern high latitudes in summer, emphasizing wildfires as a key driver of HCHO interannual variability in Alaska, Siberia and northern Canada using satellite HCHO and SIF retrievals and then GEOS-Chem model. We show SIF is a tool to understand biogenic HCHO variability in this region.
