Welcome to CASS

Center for Autonomous Sensing and Sampling

What is CASS

The mission of the Center for Autonomous Sensing and Sampling is to explore, advance, and develop complete adaptive and autonomous sensing and sampling systems for use in the atmosphere, on the ground, and in the water and to help facilitate the integration of this technology across various disciplines and institutions. We achieve this by bringing together, faculty, staff, and students from a wide range of disciplines such as  electrical engineering, computer science, data science and analytics, chemistry, geography, civil engineering, aerospace and mechanical engineering, physics, and meteorology. Areas of research focus currently include atmospheric chemistry, boundary layer structure and dynamics, data processing and visualization, earth science, and solution-based engineering.

OU and OSU Take Off to Support Atmospheric Research

CopterSonde aricraft

During August 2020, teams from the University of Oklahoma's (OU) Center for Autonomous Sensing and Sampling (CASS) and the Oklahoma State University's (OSU) Unmanned Systems Research Institute (USRI) joined forces at OU’s Kessler Atmospheric and Ecological Field Station (KAEFS) to conduct innovative atmospheric research using unmanned aircraft systems (UAS) or drones, which could lead to improved weather forecasts. Both the OU and OSU teams are developing and testing state-of-the-art UAS, instrumented with meteorological sensors designed to collect precision atmospheric data in the Earth’s lower atmosphere, which can be ingested by weather forecast models. Despite the challenges of COVID-19, the scientists and engineers from CASS and USRI were able to maintain safe practices and socially distance as they worked to together to push the envelope of UAS atmospheric research.

As a part of a collaborative team of researchers, the Center for Autonomous Sensing and Sampling and the Center for Analysis and Prediction of Storms at the University of Oklahoma received a NASA grant to develop improvements for low-altitude weather forecasting. This team is one of five university teams from across the nation selected to examine a range of technical areas in support of NASA’s aeronautics research goals.

The lead for OU’s contribution to the collaborative grant is Phillip B. Chilson, director of the Center for Autonomous Sensing and Sampling, faculty member in Advanced Radar Research Center and professor in the School of Meteorology.

CASS Research Assistant Selected to Participate in Prestigious Summer School Program

Brian Greene

Brian Greene, a Ph.D. student in the School of Meteorology and a research assistant with CASS, was recently selected to participate in the “Field Experiment on Submesoscale Spatio-Temporal Variability in Lindenberg” (FESSTVaL) summer school program. Although postponed in response to the global COVID-19 pandemic, this program will ultimately take place for two weeks in Lindenberg, Germany (a short train ride outside of Berlin), and is led by a diverse panel of international experts on topics such as convective scale observations from different platforms and sub-mesoscale dynamics and modeling.
