SHIFT

The Surface Biology and Geology (SBG) High Frequency Time Series (SHIFT) was an airborne and field campaign that occurred over several weeks in 2022 in support of NASA's SBG mission. The study area included a 640-square-mile (1,660-square-kilometer) region in California's Santa Barbara County and coastal Pacific waters. 

The primary goal of the SHIFT campaign was to collect a repeated, dense time series of visible to shortwave infrared (VSWIR) airborne imaging spectroscopy data. Those airborne observations were gathered in coordination with field measurements taken in both inland terrestrial and coastal aquatic areas by a team of research collaborators from academic institutions. 

The SHIFT campaign leveraged NASA's Airborne Visible-Infrared Imaging Spectrometer-Next Generation (AVIRIS-NG) facility instrument to collect weekly VSWIR imagery across the study area.

The SHIFT campaign: 

• enabled the NASA SBG team to conduct traceability analyses related to the science value of VSWIR revisits without relying on multispectral proxies; 
• enabled the testing of algorithms for consistent performance over seasonal time scales and end-to-end workflows including community distribution;  
• provided early adoption test cases to SHIFT application users; 
• cultivated relationships with basic and applied science partners at the University of California Santa Barbara Sedgwick Reserve and The Nature Conservancy’s Jack and Laura Dangermond Preserve.
