High-flying instrument helps scientists evaluate aircraft impacts

Article Abstract:

A new mass spectrometer has been developed by scientists at the Air Force Research Laboratory in Hanscom, MA. It is capable of measuring emissiosns at the part-per trillion level and is able to sample every hundreth of a second. John Ballenthin, the atmospheric physicist who spent five years as part of the team developing the new mass spectrometer, said that it is unique in its combination of ruggedness, portability, time responsiveness, and sensitivity. The instrument is approximately one-half to one-third the size of an ordinary mass spectrometer, and is positioned inside a chase plane which follows behind a jet, airplane or rocket to analyse its emissions.

Application of elastic lidar to PM10 emissions from agricultural nonpoint sources

Article Abstract:

There is a need to quantify PM10 emissions from nonpoint sources in order to conform to air quality standards effectively. A potentially efficient tool in measuring PM10 emissions from agricultural nonpoint sources is the light detection and ranging or lidar. It enables the description and modelling of plume dynamics, measurement of average wind speed and direction, quantitative sampling of dust missed by point sampling arrays and the generation of temporal and spatial information on nonpoint source emission variability.

Comment:

Lidar is used to quantify PM10 emissions from nonpoint sources in order to conform to air quality standards effectively
