Altitude and Geographic Sensitivity Characteristics of the AIRS Satellite Spectrometer and Drift Correction Using Methane (CH4) Data
We analyzed AIRS CH4 volume mixing ratio (VMR) Standard L3 v6/v7 IR-Only Daily products and ground-based measurements from 16 stations of the Network for the Detection of Atmospheric Composition Change (NDACC) at 24 pressure levels from 1000 to 1 mbar. We assessed the dependence of maximum AIRS sensitivity on latitude....
