The Campaign
The Western Diversity Time Series (WDTS) is an ongoing NASA field campaign focused on monitoring California’s ecosystems and providing essential data on natural disasters through multispectral imagery. Since 2020, WDTS has conducted five deployments across Southern California during fall and spring. NASA’s ER-2 aircraft is equipped with remote sensors such as MODIS/ASTER Airborne Simulator (MASTER), Airborne Visible/Infrared Imaging Spectrometer (AVIRIS), Hyperspectral Thermal Emission Spectrometer (HyTES), and Pushbroom Imager for Cloud and Aerosol Research and Development (PICARD) to collect VIS-SWIR and TIR airborne images. WDTS continues the work from the HyspIRI Airborne campaign that took place from 2013 to 2018.
