A database of modeled gridded dry deposition velocities for 45 gaseous species and three particle size ranges across North America

This is a database of modeled two-year (2016-2017) average dry deposition velocities (Vd) for 45 gaseous species and three particle size ranges at a 15 km by 15 km horizontal resolution across North America. The dry deposition schemes of Zhang et al. (2003) and Wu et al. (2021) were used for gaseous species while the scheme of Zhang and He (2014) was used for the three particle size-ranges to calculate hourly Vd, which were then aggregated into annual average Vd.
