Hello! Please take a look on http://www.osm.org/node/10948894571, http://www.osm.org/node/10948894570. what is the difference between reduce_air_pollution_pa:kgs and reduce_air_pollution_pa_kgs?

Please don‘t mark unknown values as dot.

Are you sure, that the unknown tags (I assume tree property regarding air purification) are visible on the tree (on ground verification)? If this are extern calculation values (based on size, genus, ..) : please don‘t store the values to OSM (only the necessary based parameters)
