Can I add more recent pollution & precipitation data?

No. Unfortunately, the i-Tree Database system is limited to accepting precipitation and pollution data from the years listed in the drop down menus. User submitted pollution and precipitation data has to be integrated with larger global preprocessed weather data in the underlying i-Tree processing s...

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...

The species list available is based off regional i-Tree Streets climate zones https://www.itreetools.org/streets/images/climate_zones.jpg.
