The 2017 Decadal Survey identified Earth's Planetary Boundary Layer (PBL) as an Incubation-Targeted Observable, acknowledging limitations in current observation capabilities. To address these challenges, the 2024 Westcoast & Heartland Hyperspectral Microwave Sensor Intensive Experiment (WH²yMSIE) was deployed combining multiple observational platforms—space, airborne, and ground-based—utilizing passive and active sensors with participation from over twenty institutions across government agencies, academia, and industry. WH²yMSIE captured diverse PBL regimes, with particular focus on demonstrating the CoSMIR-H instrument for potential space deployment of hyperspectral microwave technology. The complementary APEX experiment provided validation through active sensors plus dropsonde measurements from the under-flying G-III aircraft. Together, these campaigns generated unprecedented datasets enabling advanced multi-sensor approaches to PBL sounding. This session welcomes presentations on improved PBL retrievals utilizing WH²yMSIE and APEX datasets, with a focus on synergistic multi-sensor approaches informing PBL mission architecture decisions and advancing remote sensing technology transition to operational satellite missions.
