Ozone is arguably the most important trace gas in the atmosphere, and improved monitoring of ozone throughout the atmosphere is essential. This Phase 2 project continues the development of a complete, automated system for measuring ozone from on board commercial aircraft. There is already one program within NOAA, CAAMP (Commercial Aircraft Atmospheric Measurement Program), for measuring a variety ...

In our Phase 1 work we were able to replicate and build on recent results at NIST with superconducting transition (SCT) thermometers, which suggested that dramatic improvements may be achieved in detectivity and range of application, of cryogenic electrical substitution radiometers. Cryo-ESR's are widely used as the most accurate absolute standards of radiative flux and irradiance. In Phase 2, we ...

Lidar systems offer considerable promise for the acquisition of a variety of atmospheric variables with very high spatial and temporal resolution from airborne platforms. Ground-based lidar systems have been demonstrated that measure aerosols, water vapor, and ozone, and airborne windsensing lidar have been flown on several military aircraft. The growing number of commercial airliners, however, of ...

The objective of this research project is the development of an Autonomous Microbial Sampler (AMS) that will obtain uncontaminated and exogenous DNA-free microbial samples from deep-sea hydrothermal vents and other aquatic ecosystems. Sampling with the AMS may be conducted using manned submersibles, Remotely Operated Vehicles (ROV), Autonomous Underwater Vehicles (AUV) or during hydrocast operatio ...

Balloon-borne radiosondes are used extensively to collect meteorological data in atmospheric research programs funded by NOAA, WMO, DOD, DOE and others. The launch of radiosondes requires skilled personnel at each launch site to perform tasks such as balloon filling, sonde pre-conditioning and attachment, and physical release of the equipment. At present no low-cost, simple, lightweight, and rob ...

This project will design and deliver a high accuracy monitor for the photo-chemically coupled pollutants nitric oxide, nitrogen dioxide and ozone using infrared absorption spectroscopy with quantum cascade (QC) lasers. The target molecules are monitored at air quality stations worldwide using instruments which require frequent calibration and are subject to significant chemical interferences (in t ...
