Reviewer 1 Report
Dear Authors,
I have the following comments regarding your manuscript:
First of all, I would suggest changing the manuscript communication from the Article to the Review.
Page 3, line 102 " major ion, ..."
Instead, " major ion, ..." I would suggest "different chemical elements,
In the second chapter (Page 3,4,5), you can also include a Table for more detail preview.
Page 6, line 245 chapter 3. Results and discussion
because you present results which are NOT yours, here I would suggest to rename this chapter as: Overview of groups results and discussion
In your manuscript you discuss PM 2.5 micrometer particles. It should be mention that it is important to measure and monitor also bigger particles as PM 2.5. Because people usually breathe all scale of particles sizes; not only particulate matter with 2.5 micrometer size! Therefore is should be included into the models and into the measurement techniques.
In the text you often mention samples collected in Delhi
I would suggest better explain the conditions of samples, samples collection, location, type of samples from where, sample method preparation for measurement, sample volume, etc. You can also specify this and compare it in the table.
Page 19, line from 694, in the subchapter: 3.6. Potential health impact offline particulate matters using oxidative potential
In this subchapter, it is also important to mention the neurological and mental diseases due to the toxic vehicle emissions (gases as well as solid state form). As the small nanoparticles penetrate into the blood and toxic gases emissions are attached to the oxygen and inhaled.
Please include also some references.
At the end of the manuscript please include table of all abbreviations used in the text.

Reviewer 2 Report
Review of "Air pollution in New Delhi during late winter: An overview of a group of campaign studies focusing on composition and sources" by Talukdar et al., 2021.
I am overall fine with this overview over recent studies on composition and sources of pollution in New Dehli in late winter. Just a couple of suggestions:
1) It should be highlighted that recently PM2.5 might play a role in COVID-19 outbreak transmission as shown in some recent studies:

2) Try to highlight in the paper what can be defined local and transported pollution that usually are not catch by regional models.

3) English should be revised, as some sentences are not clear.
