The data needs of UFORE depend to a certain extent upon the nature of the output desired -- i.e., what forest functions or values are to be quantified. See the Manual for details.

All Projects must contain field data inputs. In addition, if sampling conducted, the following variables are required:

  • Study area boundaries and size
  • Land use categories and sizes (required if study area is stratified)
  • Number of plots in each land use strata

With these data the modules describing forest structure and carbon sequestration will be able to function. For calculation of biogenic VOC emissions and pollution effects (not available in UFORE for Windows 1.0 but obtainable through the original SAS® program), the project must contain hourly weather and pollution concentration data. These data are available for the United States for the year 2000 at no cost from the USDA Forest Service office in Syracuse, NY ( support).

Weather data

Hourly weather data are necessary to analyze:

Boundary layer data

Twice daily sounding measurements are needed to calculate percent air quality improvement due to pollution removal. Available from the Forest Service office in Syracuse for some areas or from NOAA, see the Manual.

Air pollution data

Hourly pollution concentration data are required to analyze:

  • air pollution removal by the urban forest
  • relative ranking of species effects on air quality
