Measles is spread through respiration (contact with fluids from an infected person's nose and mouth, either directly or through
aerosol transmission), and is highly contagious - 90 % of people without immunity sharing a house with an infected person will catch it.
In the latest issue of the American Journal of Respiratory Disease, Philip Thompson and colleagues note that seals «by their nature bark and cough considerably, giving rise to obvious opportunity for
aerosol transmission».
* For more information on the aerosolized transmission of Dog Flu, see Review of
Aerosol Transmission of Influenza A Virus on the CDC website.
In general, the risk of
aerosol transmission increases with proximity and duration of exposure to the source; however, once aerosolized, certain pathogens may remain infective over long distances, depending on particle size, the nature of the pathogen, and such environmental factors as temperature and humidity.3

See notes on
aerosol transmission at the end of this document for further information.
The isolation room should also have independent, adequate ventilation to decrease the risk of
aerosol transmission.
Less common routes of exposure include contamination of mucous membranes (i.e., eyes, nose, mouth) and
aerosol transmission.
Not exact matches
Evidence suggests that Ebola virus is most often transmitted by direct contact, but there is concern that
transmission could occur through inhaled
aerosol particles — which may be generated by many different medical procedures.
Highly pathogenic avian influenza A / H5N1 virus can cause morbidity and mortality in humans but thus far has not acquired the ability to be transmitted by
aerosol or respiratory droplet («airborne
transmission») between humans.
The particle soot absorption photometer collects
aerosol particles on a substrate and measures the change in light
transmission relative to a reference filter.
Transmission is
aerosol and ingestion, but healthy appearing puppies is a major source.
The three main routes of pathogen
transmission are contact,
aerosol, and vector - borne
transmission.3 BOX 1 outlines some of the more common zoonotic pathogens encountered in veterinary practice and their routes of
transmission.
The most common means of
transmission is through
aerosols generated by horses with cough; therefore, infection can spread many feet, particularly in closed airspaces.
The virus is shed primarily in respiratory discharge and
transmission can be via direct contact, fomites (contaminated objects such as hands, surfaces, clothing, etc.), droplets, and
aerosol spread.
Transmission occurs via an
aerosol - droplet route, direct contact, or possibly by contact with contaminated objects.
For example, they predicted the expansion of the Hadley cells, the poleward movement of storm tracks, the rising of the tropopause, the rising of the effective radiating altitude, the circulation of
aerosols in the atmosphere, the modelling of the
transmission of radiation through the atmosphere, the clear sky super greenhouse effect that results from increased water vapor in the tropics, the near constancy of relative humidity, and polar amplification, the cooling of the stratosphere while the troposphere warmed.
There were lots of studies of atmospheric
transmission (and hence
aerosol optical depth) starting with the work of Marvin and later Hand of the National Weather Service.
Building this chart helped me to learn about volcanoes, their release of
aerosols to the stratosphere with resulting reduction of sunlight
transmission through the atmosphere.
The repercussions of the ongoing atmospheric
aerosol spraying assault (combined with the constant bombardment of radio frequency
transmissions), has now pushed our planet well past the breaking point.
Or does it show the signature pattern of powerful radio frequency / microwave
transmissions interacting with aircraft - dispersed atmospheric
aerosols?
The annual average is about 0.25 of the peak — but you expect as well that the reflected SW would not vary as much as you suggest albedo of oceans being influenced by «solar zenith angle, wind speed,
transmission by atmospheric cloud /
aerosol, and ocean chlorophyll concentration.»
«Measurements at a sea platform show that the ocean surface albedo is highly variable and is sensitive to four physical parameters: solar zenith angle, wind speed,
transmission by atmospheric cloud /
aerosol, and ocean chlorophyll concentration.»
The satellite photos already shown in this post unarguably reveal heavy atmospheric manipulation from extremely powerful radio frequency / microwave
transmissions and atmospheric
aerosols.
Like sound waves, microwave
transmissions ripple through the atmosphere, leaving their telltale signature on the geoengineering
aerosol laced cloud cover.
