Load Is Emitted Against Settled
The claim
Atmospheric dust load is set by the ratio of emission to deposition rate, so a long-lived plume requires weak deposition as much as strong emission.
01Mechanism
Concentration is a balance between sources and sinks; deposition depends on particle size and precipitation, which vary independently of emission.
02Prediction
Load should track the ratio across regions.
03Refutation
Load tracking emission would remove deposition.
