different dust values

Weather

Dear all, I have checked dust in the air, but I get two different values ​​when I zoom in or out. Same time, same place, of course.. Do you have an idea? Thank you.

We checked this and it is in the source data as well. The difference is that at lower zoom it shows the SILAM model. At higher zoom it is the SILAM EU model. Both obviously work differently with dust concentrations from fires in Canada: https://x.com/Ventuskycom/status/19323379267272581...

SILAM EU would be more correct - the smoke remains rather high and at 10 meters the concentrations are not that high.

thank you, at what height does the SILAM model measure and where the SILAM EU model? At what height is the maximum dust concentration usually?

Both are at 10 meters. It's just that one model thinks it will reach this layer, and the other thinks it will stay around for example 1000 meters. It’s very difficult to determine how much of that dust will actually fall to the ground.
