Sensitivity Analysis of 1,3-Butadiene Monitoring Based on Space-Based Detection in the Infrared Band

Round 1

Reviewer 1 Report

The monitoring of the 1,3-butadiene in the atmosphere has great significance. The manuscript provides a method for the space-based infrared detection of 1,3- butadiene and also provides a reference for selecting the appropriate band for the detector.

In my opinion, it is a valuable work and is also in line with the scope of the journal. Based upon this, I consider the work to be suitable for publications after revision.

Following are my comments:

1. The introduction about the space-based 1,3-butadiene detection needs to be more detailed. The research status, the novelty and advantages of the proposed method should be more clarify.

2. Line 170: Figure 2 might be Figure 3.

3. It is necessary to discuss the interference of major gases exist in the atmosphere (O2, CO2…) when select appropriate band for the 1,3-butadiene detection.

4. Have field tests been conducted?

Reviewer 2 Report

Sensitivity analysis of 1, 3-butadiene monitoring based on 2 space-based detection in infrared band

A very well written work with very useful data and information, the article is acceptable for publication after minor revisions

·         Please use new references.

·         Keep the same style of the references see the model of the journal.

·         Why the choice of the concentration range of 1,3-butadiene  is between 0 and 10 ppm why not more?

·         Page 7 line 192 : the authors said that the absorption of atmospheric background radiance by 1,3-butadiene is greater than other bands, is there an explanation for this.

·         Page 8: the formula (13) should be moved to the section Data and Methods.

·         Was it not possible to make comparisons with other studies to find out the effectiveness of this method for modeling the atmospheric background radiance?

Reviewer 3 Report

The work presented in this article is well grounded in theory. It mitigates problems with other methodologies for the measurement of 1.3 butadiene in the atmosphere. It is therefore an important advance in the area of atmospheric chemistry and pollution. In my opinion it is well proposed and developed.
