Results on verification and validation of OOV-TET1 multi-spectral camera observations within the FireBIRD project

Abstract

Since November 2014, the OOV-TET1 Satellite is operated by DLR as part of the FireBIRD mission. Within the project the multispectral camera payload (MSC) became the mainly operated experiment. Its spectral and geometrical characteristics are designed to detect and observe high temperature events, especially wildfires, active volcanoes, which require a large temporal and radiometrical dynamic range and good spatial resolution. In order to detect, to discriminate and to characterize occurrences of sides with temperatures around 1000 K, but limited spatial extend, the camera system is equipped with spectral bands in near, mid, and thermal infrared as well as in visible range, having a ground resolution of 160m. This makes the instruments sensitive for remote sensing of events with thermal features in normal temperature range. Such topics are underground coal fires, thermal anomalies, observation of sea surface temperatures etc.
