Public and commercial application of NOAA developed products such as climate observations, weather products, and datasets are underutilized by public decision makers, infrastructure asset owners, or the public. Communities realize the risk posed by increases in storm intensity, flooding, and heat waves. However, communities lack understandable models targets to stakeholder questions that are affor ...

The use of unattended floats, platforms, and drones addresses the immense challenge of cost-effectively characterizing the chemistry of the oceans. The proposed program strengthens this capability by demonstrating the feasibility of Laser Fluorescence Enhanced Flame Spectrophotometry (LFEFS) for the simultaneous and high precision measurement of calcium and strontium. These are key elements of the ...

Recent theoretical studies of eddy flux correlation have suggested that the commonly used assumption of dry air having no net flux is erroneous and can lead to significant errors in reported observations. Presently, dry air density is calculated indirectly from measured temperature, pressure and relative humidity, all of which contribute to increased uncertainties in the result. If instead the den ...

Mesa Photonics has developed laser-based gas sensor technology compatible with UAV deployment. Our Airborne MUlti-Gas Sensor (AMUGS) technology is based upon two-tone frequency-modulated spectroscopy (TT-FMS). TT-FMS retains the advantages of near-infrared diode lasers while pushing detection sensitivity more than two orders of magnitude closer to the theoretical limit. Phase I results demonstrate ...

There has been a renewed push across NASA centers and programs to make Systems Engineering & Integration (SE&I) processes more efficient and results-oriented than the current cumbersome and expensive cross-checking processes using text documents, and transition to a repeatable and a cost-effective process of Model Based Systems Engineering (MBSE). In parallel, Systems Health management (SHM), with ...

In Phase II, the QSI-Vanderbilt team seeks to develop a system-level diagnostics and prognostic process that incorporates a "sense and respond capability," which first uses error codes and discrete sensor values to correctly diagnose the system health including degradations and failures of sensors and components, and then invokes appropriate prognostics routines for the assessment of RUL and perfo ...

Particle size distribution (PSD) is a fundamental environmental measurement, with diverse biogeochemical applications including carbon cycle science, ecosystem and fisheries modeling, and harmful algal bloom (HAB) detection/prediction. There is optimism that estimates of PSD will be available from ocean color measurements (such as NASA's upcoming PACE mission), and will be able to help constrain g ...

Environmental species measurement on airborne atmospheric research craft is a demanding application for optical sensing techniques. Yet optical techniques offer many advantages including high-precision, fast response, and high species selectivity. Balloonsonde, kite, unmanned aerial vehicle (UAV), or glider deployment demands that sensors meet stringent size, weight and power requirements. Few mea ...

A prototype high temperature, single optical fiber thermal imaging system will be developed, tested, and delivered to GRC. The components of the instrument will be specified in detail, designed, fabricated, and purchased where appropriate. The illumination and imaging system will be assembled and system tests will be performed. Given a set of calibration images produced by the diagnostic, the i ...

Noise measurement of aerospace vehicles is difficult and usually requires expensive, specialized facilities. With the proliferation of UAVs there is need for noise data, both for ISR and non-military vehicles. Wind tunnel testing is common and much less expensive. The innovation is a novel in-flow microphone array combined with the start of the art Functional Beamforming algorithm that makes it p ...
