Can I add more recent pollution & precipitation data?

[azelaya]

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 servers. Therefore, the year currently accepted by i-Tree Database may typically be a couple years behind the current year. The database system is periodically updated with more current global weather, and users can check back to submit more current individual pollution and precipitation years datasets for model integration.
