Re: Sepcificity of Formulas

although there are 7000 or so individual tree and shrub species available in the i-Tree list, there are only a small amount of species specific growth equations available. Probably less than 200 although new ones are being integrated in the model. If no equation could be found for an individual spec...

Can I add pollution datasets for different locations with a new international city?

Only one set of pollution data for a given year can be integrated for a new international city location at this time. We understand that many cities have multiple pollution monitor locations to account for variation of pollution in a city, and it would improve modeling capabilities if data from mult...

Why do Design species change for some nearby locations?

i-Tree Design uses the address entered to generate a generic regional list of species. The species list available is based off regional i-Tree Streets climate zones https://www.itreetools.org/streets/images/climate_zones.jpg.

Re: VOC emissions

No. the VOC outputs are not considered in net carbon sequestration estimates. The Eco model VOC estimates are determined in a separate modeling module.

Why are Eco & Streets estimates different for the same trees

Eco and Streets have completely different underlying methodologies which accounts for much of the differences in the model estimates. This is explained in the documentation that describes the underlying functions, assumptions and limitations of these models in the archives section of the website. ht...
