Pre-EUCREX Intercomparison of Airborne Humidity Measuring Instruments

Intercomparison of remote sounding instruments

[1] When intercomparing measurements made by remote sounders, it is necessary to make due allowance for the differing characteristics of the observing systems, particularly their averaging kernels and error covariances. We develop the methods required to do this, applicable to any kind of retrieval method, not only to optimal estimators. We show how profiles and derived quantities such as the t...

Intercomparison of the Sensitivity and Accuracy of Radon Measuring Instruments and Methods

Radon testing in the US has reached a plateau with about two dozen different types of instruments and methods being used to make about one million measurements per year. Knowledge of the sensitivity and accuracy of radon testing instruments can make it easier for testing firms and home inspectors to select the most appropriate device for their radon testing program. This paper compares the sens...

Use of direct-reading instruments for measuring airborne nanoparticles in the workplace

This work strived to increase knowledge of assessing airborne nanoparticles in the workplace by characterizing nanoparticle concentrations in a workplace using directreading instruments, evaluating a DC2000CE diffusion charger, and the creation of a personal diffusion battery (pDB). Direct-reading instruments were used with aerosol mapping and task monitoring to evaluate airborne nanoparticle c...

Intercomparison and evaluation of four semi-continuous PM2.5 sulfate instruments

The development and evaluation of time-resolved (minutes) measurement technologies to characterize the physical and chemical make up of ambient aerosols/particulate matter in the atmosphere are essential to our improved understanding of aerosol process science, source attribution, and population exposure. During the PMTACS-NY summer 2001 campaign in Queens/New York, a wide variety of on-line ae...
