Sentences with phrase «aerosol types which»

In this case the computed forcings incorporate the effects of other aerosol types which have a similar spatial distribution to sulphate aerosols, such as nitrate aerosols or carbonaceous aerosols from fossil fuel combustion.

Not exact matches

The latter type of sensors, Robock notes, could directly measure the size distribution of aerosols, which could help researchers better model their effects on climate.

The PNNL team is currently applying the approach, which grew out of the Aerosol Climate Initiative, to other types of simulations, so that future high - resolution climate models will solve the mystery surrounding aerosol - cloud interaAerosol Climate Initiative, to other types of simulations, so that future high - resolution climate models will solve the mystery surrounding aerosol - cloud interaaerosol - cloud interactions.

Two other types were isolated from two animals which had received a low dose stationary phase aerosol infection.

Methods: In this new approach, the team began with an atmospheric aerosol sample that contains thousands of molecules formed in the reactions of ozone, a common atmospheric oxidant, with limonene, a molecule emitted by various types of trees, which is responsible for the citrus scent found walking among the orange trees.

In addition, model intercomparison studies do not quantify the range of uncertainty associated with a specific aerosol process, nor does this type of uncertainty analysis provide much information on which aerosol process needs improving the most.

Second, the upsurge in Graffiti art (Street or Aerosol Art), which blossomed especially in America - Philadelphia, then New York - where it morphed into a major type of urban contemporary art.

These uncertainties are reflected in the model simulations of aerosol concentrations which all show similar total amounts, but have very different partitions among the different types.

Volcanic events and some types of human - made pollution, both of which inject sunlight - reflecting aerosols (i.e., tiny particles) into the atmosphere, lower temperature and are examples of forcings that drive decreases in temperature.

The study focuses on one proposed type of SRM, known as a «stratospheric aerosol injection», which involves sending up substances to the stratosphere that are known to have a cooling effect on the climate.

You discuss what you call «aerosols», by which I think you mean various types of cloud nuclei.

The two main types, she says, are solar radiation management, which mostly refers to injecting sulfur aerosols into the stratosphere to reflect sunlight and, hence cool the Earth; and carbon dioxide removal, which is best illustrated by direct air capture — machines that take carbon dioxide out of the air and store it underground.

And a new NASA climate satellite called Glory, which will launch late in 2010, will carry a new type of aerosol sensor that should be able to distinguish between aerosol types more accurately than previous instruments.

Anthropogenic emissions include many types of GHG's as well as particulates such as black carbon and sulfate aerosols, each of which has a different effect on the atmosphere, and a different atmospheric lifetime.

In addition to the data from the radiometers, the Berkeley Lab scientists will get supplemental data by taking advantage of a separate, in - depth DOE climate study at the same location, which is using additional instruments and a balloon - borne sounding system to get information on temperature, cloud cover, the density and types of aerosols or pollution particles, heat fluxes and other climate variables like precipitation.
