From May 5 to 7, the 2026–2030 Landsat Science Team met for their first in-person meeting at the Earth Resources Observation and Science (EROS) Center in Sioux Falls, SD. The three-day event, co-moderated by Landsat 8, 9, and 10 Project Scientist Chris Neigh, allowed leaders from USGS and NASA to begin work on a vision for the upcoming five-year period.
Attendees shared their current work and a vision for the future of the Landsat program. Participants received comprehensive status updates on the upcoming Landsat 10 project, the ongoing interagency and international collaboration on the Harmonized Landsat and Sentinel-2 (HLS) data products, and detailed plans for Collection 3 (C3).
Throughout the event, team members representing funded, international, and federal programs showcased the far-reaching impact of Landsat data across various Earth science disciplines, spanning snow cover mapping, atmospheric correction, water quality monitoring, evapotranspiration, agricultural applications, volcanic monitoring, and more.
The meeting culminated in focused breakout sessions, where experts drafted vital recommendations across four key technical areas to guide future mission data processing:
Surface Reflectance
The surface reflectance working group identified several priorities, including topography and adjacency corrections, Bidirectional Reflectance Distribution Function (BRDF) correction, and enhanced cloud masking with consistent approaches for HLS data products. Key recommendations included incorporating CMIX2 cloud masking results into future collections and mapping out C3 toolkit dependencies for user-applied corrections.
