Updated land use/land cover data -- Its effects on estimates of biogenic emissions in the North Carolina urban airshed modeling effort
In North Carolina, emissions from vegetation comprise the bulk of the volatile organic compound (VOC) inventory. Estimation of these emissions will thus play a substantial role in the regulatory strategy suggested by modeling. The Urban Airshed Model (UAM), as available from the EPA, presently estimates biogenic emissions from land use/land cover data more than 20 years old. Recent data obtained from the US Forest Service`s periodic Forest Inventory and Assessment surveys have been gridded to the modeling domain. Emission estimates based upon these data will be compared with those from the older land use/land cover data set.
