In spring 2022, researchers with NASA's Surface Biology and Geology (SBG) mission conducted a field campaign called SHIFT (SBG High Frequency Time series), part of the SBG AVIRIS-NG 2022 Dense Time Series Campaign. (Read more about the AVIRIS-NG sensor here.) SHIFT is collecting airborne visible-to-shortwave infrared (VSWIR) spectral imagery to describe the phenological changes at approximately weekly cadence for sites across the Dangermond Preserve and the Sedgewick Reserve, both located in Santa Barbara County, California.
During UMBC's spring break (03/20/22-03/26/22), Petya Campbell and Fred Huemmrich (both 618/UMBC) participated in the campaign. Dr. Campbell joined the field team in California to collect representative vegetation samples and supporting measurements of canopy composition, stand parameters, and photosynthetic pigments. She sent leaf samples overnight to NASA GSFC, where Dr. Huemmrich measured leaf biophysical parameters and optical properties.
In summer 2022, Drs. Campbell and Huemmrich along with a SBG student intern will combine the AVIRIS imagery and the field data in a biophysical model to assess the dynamics in vegetation photosynthetic pigments and gross primary productivity.
