Will be interesting to see what this looks like in the cooler seasons. Temuco and Santiago especially are in bowls, and with lots of diesel vehicles and woodburning stoves, these cities are very smoggy in the winter.
Cool! Is there historical data available? It'd be cool to have a slider to go back in time and maybe loop over the data over a specific range to show how it evolves.
Also, what bounds this to Chile? It seems that using location coordinates and standardising the fields on each sensor type may help unify data from any weather station.
Im not sure if the goverment organization has a historical database, because the api updates the sensors values with the last data available and the are no docs if i rebember correctly.
Regarding your second question, idk really, if there is public data from other countries it could be formatted to a common format for the app, it is a nice idea, ty.
maybe there is a time offset between the readings from the two sources. Other factor could be the quality of the sensor itself or how google manage to get that data.
