WDTS
The Western Diversity Time Series (WDTS) field investigation was focused on observing California's ecosystems and providing critical information on natural disasters such as volcanoes, wildfires, and drought through multispectral imagery.
WDTS collected seasonal visible to shortwave infrared (VSWIR) and thermal infrared (TIR) airborne imagery using instruments including the Airborne Visible/Infrared Imaging Spectrometer (AVIRIS-C), MODIS/ASTER Airborne Simulator (MASTER), Hyperspectral Thermal Emission Spectrometer (HyTES), and Pushbroom Imager for Cloud and Aerosol Research and Development (PICARD) on a NASA ER-2 high-altitude platform.
WDTS aims to provide a benchmark on the state of ecosystems against which future changes can be assessed. WDTS started in 2020 and is a continuation of the HyspIRI Airborne campaign which took place from 2013-2018.
