| Abstract | Sepulveda et al. describe the retrieval of tropospheric CH4 in the mid-IR region using the PROFFIT algorithm. Two approaches are evaluated for removing the effects of stratospheric variability: (i) profile retrieval which uses the shape of the CH4 lines to infer the vertical distribution, (ii) use the column HF to estimate the stratospheric CH4 column which, together with the retrieved total CH4 column, is used to infer tropospheric CH4. The results are compared with in situ measurements of tropospheric CH4. The profile retrieval technique (i) appears to give better results. For the remainder of this review, I will refer to method (ii) as the "HF procedure". |
