Abstract

S1. Errors in GEOS-5 meteorological parameters 1Errors in the GEOS-5 meteorology are quantified here using observational data from ISH and 2 ISCCP. Results are exploited in Sect. 4 to evaluate the sensitivity of NO 2 columns simulated 3 by GEOS-Chem to meteorological inputs. 4To better understand the reliability of the meteorological fields, the analysis is conducted for a 5 comprehensive set of parameters including air temperature, RH, tropospheric water vapor 6 path, surface air pressure, 10m wind speed, cloud fraction, COD, and precipitation. 7Measurements are taken from the ISH dataset for air temperature, RH, surface air pressure, 8 wind speed and precipitation, and are taken from ISCCP for tropospheric water vapor path, 9
