Interactive comment on “Rugged optical mirrors

I think this work is very important for the future operations of TCCON and NDACC stations in remote and harsh environments. This paper has the potential to be referenced numerous times by both TCCON and NDACC networks. However, as reviewer #1 already stated, the authors need to deepen the paper a bit more, specifically on the characterization of the results using the new mirrors. I recommend th...

Side-by-side intercomparisons of ground-based remote sounding instruments are of very high interest within the NDACC (Network for the Detection of Atmospheric Composition Change) community. There have been earlier studies (e.g., Murphy et al., 2001; Wunch et al., 2007) and there are planned future intercomparisons (e.g., Sung et al., to be submitted to ACP, 2008). It would be desirable to make ...

A somewhat weak point of the paper is that a clearly defined focus is not apparent: In the introduction it is said "..., it is nessessary to understand the difference between ground-based instruments that are used in satellite validation studies and this is the focus of this paper." According to the title, the validation of the ACE-FTS seems to be of equal importance. Judging from the length of...
