Research

The University of Colorado, Boulder created the Grand Challenge to cultivate partnerships with government and industry to pursue solutions for pressing challenges facing our world today. The Integrated Remote and In Situ Sensing (IRISS) initiative is a pillar of the ºÚÁÏÉçÇøÍø Grand Challenge and provides 4D measurement capabilities to study phenomena at a distance and from within. IRISS gathers data from the natural world using ground sensors, unmanned aircraft, spacecraft, and other sensor systems. This information can be used to reveal valuable insight about myriad events like climate fluctuations, drought conditions, and forest dieback.

Recent Projects

For six weeks during the summer of 2025, IRISS collaborated with more than a dozen other institutions to study the patterns and effects of hail in the midwest.

IRISS has been deploying robotic aircraft around coastal cities to collect information on temperature, winds, humidity, and atmospheric particulate matter.

Project Targeted Observations by Radars and UAS of Supercells (TORUS) aimed to improve the conceptual model of supercells. Over the course of two spring seasons (2019 + 2021) and with 42 scheduled days of coordinated deployments, the TORUS team covered about ~1,300,000 km in pursuit of storm research.Ìý

Project Hypersonic FLight in the Turbulent Stratosphere is composed of a multidisciplinary team of experts in the fields of in-situ atmospheric measurements and analysis, atmospheric modeling and forecasting, and aerothermodynamics and aero-optical modeling. Our goal is to ask and resolve questions related to how future hypersonic vehicle designs can account for the effects of ambient atmospheric turbulence and particles in the middle stratosphere.

Project Multidisciplinary-drifting Observatory for the Study of Arctic Climate (MOSAiC) is a collaborative effort with CIRES, NOAA, and CU-Boulder’s Atmospheric and Oceanic Sciences and Aerospace departments. This project will develop and deploy unmanned aircraft to operate at the farthest northern reaches of the planet to make critically needed measurements on the Arctic atmosphere and sea ice.
