Julian Claudio :: University of Colorado Boulder

Topic of EOL Internship: NCAR Balloon Borne Replicator

Abstract: The NCAR balloon borne replicator is an instrument used by MMM to replicate ice crystals in upper atmospheric clouds.  A team of German scientists working with Carl Schmitt bought two of the instruments.  However, there were no existing 3D models or engineering drawings of the instrument.  My job was to document, redesign, and create engineering drawings of the replicator so that it could be manufactured for the team of scientists who purchased the instruments.  The replicators were successfully manufactured, assembled and sent to Germany in late July.

Nicholas DeCicco :: Rowan University 

Topic of EOL Internship: Convert Legacy GENPRO-I data to the modern NetCDF format

Abstract: Changing computer architectures and language specifications, and the reduced availability (or complete unavailability) of legacy computer hardware, software compilers and storage media can make preserving access to legacy data difficult if not impossible.  GENPRO-I was a data acquisition system including a file format of the same name used by NCAR EOL to store observational weather data from the mid - 1970's to the mid - 1980's.  No remaining usable software existed to read this format. NetCDF is a modern format which may be adapted to store any type of data, and has established itself as the de facto standard for portable data storage in the atmospheric sciences.  With this project, a set of software programs were developed to convert legacy GENPRO-I data to the modern NetCDF format to make this data available once more to researchers for analysis.

Katie McMenamin :: Swarthmore College

Topic of EOL Internship: Optical Array Probe

Abstract: An Optical Array Probe detects cloud particles and measures their shapes and sizes as they pass through a laser beam and cast a shadow onto a receiving diode array.  These measurements are used to estimate the physical characteristics of cloud drops and ice crystals and to generate particle size distributions.  At high airspeeds particles move faster through the probe and the duration of their shadow decreases.  The quick response time of the diode array is critical to the recognition of small particles, which must be compensated for to avoid low skewed concentration estimates.  The time response was measured and characterized for each diode and the effects of these results on sample volumes were modeled. 

Hien Nguyen :: Union College

Topic of EOL Internship: Design and Development of NCharts for Data Processing

Abstract: EOL field projects generate a large amount of raw data everyday that needs to be processed into graphical visualization for analysis.  This process is inconvenient because it required a significant amount of time for a detailed graph to be constructed.  It is desired to have a quick and simple look at the data after it is collected.  My project at EOL during the summer is to design and develop NCharts, whic a python django server based website that can plot the raw data into interactive graphs and update them in real time basis.   All current EOL projects can be accessed on NCharts and the software provides different graphical interfaces for different types of data.  This project will reduce the amount of time needed to process the results and view them in a simple manner.

Lucas Reed :: University of Colorado Boulder

Topic of EOL Internship: Powering Remote Field Sensors

Abstract: EOL ISF has a variety of low power field sensors that require a reliable power source.  Often in remote areas, these sensors don't have access to a power outlet or other preexisting infrastructure.  The remote sensors being targeted with this project are often in the open and can utilize solar power.  To effectively power remote field sensors and to improve on the current power system, a PCB is being designed, built, tested, and implemented.  It is being designed to accept and maximize solar power, handle energy storage, and output a steady 12V low power signal for the sensor.  It is intended to fit in a small and light package that will be easy to deploy in the field.  The final product will effectively and efficiently power a variety of EOL ISF's remote field sensors.

Scott Hally :: University of Pittsburgh

Topic of EOL Internship: High Power Amplifier for the 449 MHz Modular Wind Profiler

Abstract: EOL ISS utilizes a 449 MHz modular wind profiler, a scalable radar system that profiles the wind and structure of the atmospheric boundary layer and the troposphere.  One of the important building blocks of this radar system is a high power amplifier that receives a pulsed radio frequency signal and increases its power before being emitted by the system.  In the design process of the amplifier, a series of nine tests must be run on the amplifier to characterize its performance before being implemented in the radar system.  These tests simulate possible real - life scenarios to determine how the amplifier will perform in different situations.  When these tests are conducted manually, it takes approximately two weeks to complete.  LabVIEW software was designed in order to automate each of the nine tests, which decreases the amount of time needed to test, eliminates the need for a person to test the amplifiers, and increases quality and repeatability of test results.

Julian Quick :: Humboldt State University

           Topic of EOL Internship: Live Data Monitoring Via Quality Control Metadata

            Abstract: Development of a real - time data monitoring system for aircraft instrumentation using quality control metadata.  Live data is compared to metadata, and the             results are piped to the Nagios system core as passive checks.  These results are displayed for aircraft technicians, reporting instrument failures.  Quality control                       metadata was restructured from binary to XML in an effort to simplify RAF's processing system.  A graphic user interface was developed to edit the XML metadata, and             an API was created to integrate the new metadata format into RAF's existing infrastructure. 

Brandon Butterfield :: Arizona State University

Topic of EOL Internship: Redesign of Automated Giant Nuclei Impactor

 Abstract: Size distributions of giant aerosol particles (dry radius larger than 0.5 μm) are not well characterized in the atmosphere.  Measurement is problematic for  these particles that occur in low concentrations.  The Giant Nuclei Impactor 9GNI) is a high - volume impaction system based on free - stream exposure of polycarbonate slides from the aircraft.  It operates as an automated multi axis of motion robot utilizing stepper motors for the positioning of each axis of motion.  This system reduces the number of times that the slides need to be handled.  A multi axis robot system can face several difficulties relating to the environment the instrument is exposed to during flight.  Several modifications have been made to the original design in addition to testing in stimulated environments.  The expected outcome of this project is a fully operational system that will operate on both the NCAR/NSF C-130 and GV aircraft. 

Jose Diaz :: University of Puerto Rico

Topic of EOL Internship: Multi Layer Radome Design and Experimental Characterization of Scattering and Propagation Properties for Atmospheric Radar Applications

Abstract: Water accumulated on the radome surface can significantly affect the radar signal.  Depending on the frequency of operation, rain and wind conditions, shape and material, a radome can significantly attenuate, reflect, and depolarize the radar or communication signals.  A new experimental approach to accurately characterize the scattering and propagation properties of multi layer radome under artificial rain conditions was developed over the summer.  The main goals were: 1) Present the development of a unique and automated radome station test. 2) Characterize the effective dielectric constant, tangent loss, attenuation, reflections, and induced cross - polarization for a multi layer sandwich radome for X-band under the influence of controlled artificial rain, and 3) Use the measured results to validate the analytical model proposed for estimating the drop distribution on a radome surface based on skin surface material, and area inclination.

Abstract: The first deployment of the Driftsonde at AMMA in 2006 was a huge success, but did reveal problems due to environmental conditions at 65,000 ft. As with other space and near space instrumentation, there is no second chance once a subsystem has failed. Tim will present the redesign and structural testing of the new Driftsonde gondola which is expected to improve the reliability of the system.

Jacqueline Hibbard :: University of Michigan, Aerospace and Aeronautics Engineering

Topic of EOL Internship: Cloud Radar/Lidar: C-130 Installation Design and Stress Analysis

Abstract: The Wyoming Cloud Radar (WCR) and Cloud Lidar (WCL) will be installed on the C-130 for use in the ICE-L field campaign which starts in September 2007. A new antenna was added to the WCR, but due to the configuration of the aircraft, the antenna is located approximately 13 ft from the transmitter. Jackie will present the design for a mounting structure for the waveguide that will connect the transmitter to the antenna, and can withstand the appropriate loading conditions. She will also present the design for the radar and lidar window mounting components and the analysis of these components under conditions of gust loading, emergency landing, and pressurization.

Oluleye Olorode :: Benedict College, Electrical Engineering

Topic of EOL Internship: Tracking and Positioning of a Laser Beam

Abstract: Automatic correction for drift in lidar transmitter pointing angle to maintain strict alignment of the received beam with the receiver, is critical for optimal lidar operation, especially when the lidar is operating unattended. Monitoring hardware must be capable of tracking the position of received light from a lidar system in which the signal levels are in the micro- to nanowatts region, and the backscattered light duration is in the tens of microseconds. 'Leye will present the design and implementation of the electronics and LabView code for an novel beam centering unit for the Raman-shifted Eye-safe Aerosol Lidar (REAL) which will allow the transmitted beam to be deterministically positioned to center the received beam.
