chemical data simulated over the Arctic using CMAQ model

Hourly chemical data are obtained from CMAQ v5.1 model simulations during the 4 months from May to Aug. 2008. MACCity, MEGAN-MACC, and GFED3 emission inventories are applied to the simulation for anthropogenic, biogenic, and biomass burning sources, respectively. The CMAQ domain covers the areas of the Arctic (D1 domain) and Svalbard (D2 domain) with 18km x 18km and 6km x 6km horizontal resolutions, respectively. To investigate spatial and temporal patterns of particulate matters (PM10) and photochemical species (O3, NOx, and PAN).
