Abstract: Laboratory experiments were conducted to improve the operation and calibration procedures for the ambient ROx radical detectors (ROx = HO2 + RO2 + OH + RO) based on chemical amplification. A new method for the experimental ...

Abstract: A new lightweight NO2 instrument that can be flown from a tethered balloon to give vertical NO2 profiles is described. The detection principle is the chemiluminescent reaction between NO2 and a solution of luminol. The ...
