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 ...

The proposed effort is to build a high resolution, high speed spatial light modulator (SLM) to be used in infrared (IR) spectral projectors. An IR spectral projector produces programmable spectra by dispersing light onto a programmable array, currently digital micromirror devices (DMDs), which either transmit or block selected components of the light. the light is then recombined to form complex s ...

Two, complementary techniques are proposed that are deployable on dropsondes or mobile measurement platforms and measure the scattering coefficient of atmosphere aerosols. The Phase I activity will be a proof of concept study that evaluates the relative strengths and weaknesses of the two measurement systems and combines a detailed analysis of the optical and electronic systems with a laboratory ...
