Dispersion models typically consist of 3 modules:
Transport module, immission module, impact module
Meteorology Module, Chemistry Module, Deposition module
Emission module, Transmission module, Immission module
Meteorology Module, Chemistry Module, and Transport Module
Meteorology Module, Transport Module and Deposition Module
Trajectories are an important part of which kind of dispersion models?
Gaussian models
Diffusion models
Langrangian models
Richardson models
Eulerian models
Near the earths surface, temperature increases with height
When wind speed increases with height
When wind speed is low and the radiation balance at the surface is negative
Because the distance from sun decreases
When atmospheric radiation exceeds terrestrial radiation
When warm air rises from heated surfaces
When an inversion breaks up
Chronic damage caused by air pollution can be prevented
Standards expressed in high percentiles
Limiting maximum concentration
Short term standards, e.g. Hourly means
Long term standards, e.g. Yearly means

Only valley wind
Valley- and down slope wind
Valley and up slope wind
Only down slope wind
Mountain and down slope wind
In order for a cloud to rain, cloud droplets must grow
Through coagulation and coalescence with other droplets
Through freezing and melting
And reach a size 100 times that a small cloud droplet
Through transpiration and evaporation
Through compression and density increase
Through condensation and diffusion
Which of the following radiative processes leads to energy conversion?
Reflexion
Absorption
Refraction
Diffusion
Concentrations caused at a specific point by a continuous point source vary strongly
In inversions

In neutral layers
In stable layers under strong wind conditions
In isothermal layers near the ground
The troposphere
Is the bottom layer of the atmosphere in which temperature decreases with height
Is the lower part of the planetary boundary layer
Is the lower part of the stratosphere and characterized by temperature increase with height
Consists of the planetary boundary layer and the turbulent surface layer

Averaged over the whole globe, albedo is about 5 %
Albedo is higher for snow than for bitumen
Albedo is reflectivity averaged over all wavelengths
Albedo is the ration of reflected to incoming radiation
Albedo increases with the temperature of the reflecting body
The atmosphere is characterised by
About 80% nitrogen, 20% oxygen and 1% argon content
About 0,03 CO2 and 0,05 water vapour content
About 80% oxygen and 20% hydrogen content near the surface
Rapid increase of CO2 and decrease of oxygen concentrations

Continents
Arctic
Alpine region
Oceans
