Thank you for the comments and evaluation !

In the revised paper version, we shall explain the symmetric OOp application in more details and also reduce the pixel-size section to make it easier to read.

Dear Reviewer,

Thank you very much for the detailed comments! We shall respond to each of them in details while preparing the revised version of the paper. Short answers are provided below

- regarding the aerosol attenuation of the FRP signal, we shall extend the discussion; however, we would like to point out that the 4-um AOD is an adequate parameter for this correction because the MODIS Collection 6 and 6.1 algorithm, albeit using a range wavelengths for processing, exclusively relies on the 4-um channel to calculate the FRP absolute value (Giglio et al, 2016, Eq. 16). Other bands (same paper, Table 1) serve for non-fire rejections and active fire detection. As pointed out in the paper, AOD those wavelengths can have their impact only for acceptance-rejection of near-edge fire detection. The revised paper includes more detailed discussion of the subject.

- description of methodology will be expanded

- discussion on sensitivity of the omission error estimate to the procedure of its calculation will be turned from a qualitative text to a more quantitative presentation of the conducted sensitivity studies

- we shall also expand the comparison with SEVIRI and VIIRS and make it more quantitative. However, we would like to point out that explicit estimates of the FRP detection limit of these satellites are all but absent - this was the main motivation for developing our OOp and writing this paper.

- minor corrections will all be taken into account in the revised paper

Thank you for your comments!

With best wishes

Mikhail and Rostislav
