### cloud:

Aerosol
* Most aerosols are generated by sources
  - water sources
  - used by nations
* Most aerosols come from natural sources
* Most aerosols contain a low percentage of active ingredient
  - liquid gases
* Most aerosols enter atmospheres
  - lower atmospheres
* Some aerosols are generated by economic growth
* Some aerosols are generated by rapid economic growth
  - contain toxic materials, others contain corrosive chemicals
  - follow eruptions
* Some aerosols have cool effects
  - increase heat
  - make the atmosphere warmer because they absorb energy
  - promote chemical reaction
* Some aerosols promote complex chemical reaction
* Use up or give to someone who can use it up if safe to do so.
* absorb and reflect light, producing the haze in cities
* actually help improve the accuracy of the velocity measurements.
* affect electro-optical propagation and the transfer of radiant energy in the atmosphere
  - our environment at the local, regional, and global levels
* also affect biogeochemical cycles and human health.
* also affect the Earth's radiation balance through their effects on clouds
  - atmosphere in different ways
  - properties of clouds, with a cooling effect, but a large uncertainty
  - can form under the conditions of fire or uncontrolled polymerization
  - form when gases are converted to fine particles in the troposphere
* also have an important effect on global climate
  - relationship to ozone
  - lead to cloud burning in the subtropical area
  - play an important role in the global atmosphere
  - use environmentally damaging propellants
* appear in the stratosphere and troposphere as well.
* are Ammonia ice, water ice, ammonia hydrosulfide
  - a viable method for controlling resistive behavior
  - also the nuclei around which clouds droplets form - no aerosols, no clouds
* are collections of particles suspended in gas
  - particles, suspended in air
  - colloids
  - dispensers
  - dust, water vapor, pollution, clouds, etc
  - effective only if sprayed directly onto the bee
  - excellent at increasing the reflectivity, or albedo, of the earth s atmosphere
  - far from being fully understood
  - important because they provide a location for water to condense and form clouds
  - insoluble particles suspended in a gas
  - liquid medications that are suspended in a gas that forms a mist
  - minute particles suspended in the atmosphere
  - of great interest in numerous science and engineering applications
  - part of every day experience - for example cigarette smoke, or atmospheric haze
  - particles dispersed in gas
* are particles suspended in a gas, such as air, and are often associated with haze
  - small particles or droplets in the atmosphere, with sizes on the order of a micrometre
  - small-suspended particles that scatter and absorb solar radiation
* are sprays that contain intoxicating propellants
  - propellants and solvents
  - suspensions of propellants and active ingredients such as paint or pesticides
* are the main cause of micro-centrifuge contamination
  - major uncertainty associated with global climate models
  - tiny and microscopic particles of dust, smoke and ash
* are tiny particles in the air, which can be inhaled
  - present in the atmosphere
  - such as dust and soot
* are tiny particles suspended in the air
  - solid or liquid droplets in the air
  - ubiquitous in the troposphere and stratosphere
  - under pressure
  - usually in a pressurized container
  - very fine particles of liquid or solid substances suspended in air
  - visible as haze when present in large quantities
* behave a lot like chemical vapors.
* can affect climate in many ways
  - energy inputs to the Earth, since they can block solar radiation
  - also provide sites for heterogeneous chemical reactions in the atmosphere
* can be natural, such as fog, or manufactured, such as smoke
  - projectiles when bursting
  - wet or dry liquid or solid
  - escape from the centrifuge unit and become dispersed in the air
  - have important consequences for continental-scale patterns of climate change
  - heat as well as cool
  - reflect sunlight, much like clouds
* cans Acids and drain cleaners.
* collection of particulates.
* contain gases
  - toxins
* containing pyrethrin, rotenone and pyrenone are available
  - synergized pyrethrins, resmethrin, permethrin or propoxur also are available
* cool the climate locally by scattering sunlight back into space
  - parts of planet by reflecting sunlight
* directly scatter and absorb radiation.
* disperse the substance in tiny droplets that can be inhaled or absorbed through the skin.
* essentially decrease conductivity by vastly increasing the mass of the charge carriers.
* have a cooling effect due to their ability to reflect incoming sunlight
  - effect, which offsets, in part, the warming effect of greenhouse gases
  - direct effect on the atmosphere's radiation budget
  - two-fold cooling effect on climate
  - other impacts
  - significant effects on air pollution, climate, visibility and human health
  - toxic propellants which can explode
* impact the performance of infrared, visual, and laser systems.
* interact both directly and indirectly with the Earth's radiation budget and climate.
* is collected on quartz fiber tape
  - powered by compressed air
  - self-generated upon activation of the system
  - the scientific term used to describe particles suspended in a fluid, such as air
* major means of transmission.
* oven cleaners are among the worst contributors to indoor air pollution.
* play a negligible role.
* pose a different, but equally-lethal danger
  - similar risk
* reflect solar radiation back to space, and, in so doing, cool the Earth
  - sunlight, making the surface cooler
* released by human activities are also capable of influencing climate.
* require propellants, valves, etc., as well as containers.
* resulting from human activities include sulfate aerosols and soot from fossil fuel burning.
* scatter back to space and absorb solar radiation
  - proportional solar energy to frequency
* usually contain pyrethrins.
* vary considerably by region.
* works better on greasy stains.
