Please join us for a seminar given by our four SUPER interns as they present the projects they have been working on this summer.

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. As response time increases, there is a reduction in the probe's true sample volume for 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 volume were modeled.

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 requires 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, which is 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.

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 as well as provide the intern with valuable experience.

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 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.

This presentation will cover the automation of the series of high power amplifier tests. 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.
