The DESIS Level 2A collection contains standardized (CEOS Analysis Ready Data) and systematically processed bottom of atmosphere reflectance data generated using an algorithm for the atmospheric correction of DESIS data over land surfaces using the PACO code (de los Reyes et al., 2020). The DESIS data provides reflectance values between 400nm and 1000nm with a spatial resolution of about 30 m and spectral resolution of 10.2 nm (factor 4 spectrally binned with respect to default DESIS data). The dataset is provided in cloud-optimized GeoTIFF format for direct access and download. Since 2018, the DLR Earth Sensing Imaging Spectrometer (DESIS) operates onboard the International Space Station (ISS). DESIS has acquired data worldwide for both scientific and commercial users. The continuously growing data archive supports methodical and application developments for the monitoring of the Earth’s surface. Additionally, the DESIS data archive serves as a database for recent and upcoming hyperspectral Earth-observing missions such as ESA’s CHIME. It enables long-term analysis of physical phenomena and land use changes by providing high-resolution data spanning an extended temporal range for the monitoring of a site of interest.
