A high-resolution soot particle aerosol mass spectrometer (SP-AMS) was used to selectively measure refractory black carbon (rBC) and its associated coating material using both the ensemble size-resolved mass spectral mode and the event trigger single

The impacts of soot particles on climate and human health depend on the concentration of black carbon (BC) as well as the thickness and composition of the coating material, i.e., organic and inorganic compounds internally mixed with BC. In this study

Transport and scavenging of chemical constituents in deep convection is important to understanding the composition of the troposphere and therefore chemistry-climate and air quality issues. High resolution cloud chemistry models have been shown to re

The pointing and stability requirements for the Gravity Probe B (GP-B) Relativity Mission pose a number of challenges for the star-tracking electronics. Because the telescope-gyroscope assembly operates at 2.8 K, the detector circuit's Si JFETs at th

Infrared mosaic focal plane arrays (MFPA) are complex integrated microelectronic devices whose operation is based on a large number of voltages in which the performance is very sensitive to voltage variations. Due to chip-to-chip variations, a comput
