title: High-Resolution Vegetation Traits and Fluxes during NASA's SHIFT campaign, for Dangermond Preserve, California, 2022

description: Overview
This dataset provides high-resolution (30 m) remote sensing and modeling data collected as part of the SHIFT (Surface Biology and Geology High-Frequency Time Series) campaign conducted in 2022 at the Dangermond Preserve, California. The data, sourced from AVIRIS-NG (Airborne Visible/Infrared Imaging Spectrometer-Next Generation), TROPOMI (TROPOspheric Monitoring Instrument) SIF, and outputs from the Climate Modeling Alliance (CliMA) Land model, offers valuable insights into vegetation traits, plant functional types, ecosystem dynamics, and biogeochemical cycling.
