Overview of the (A)ATSR Archive at the NERC Earth Observation Data Centre

The (A)ATSR Archive is a dedicated facility within the NERC Earth Observation Data Centre, supporting the UK Earth Observation community. It hosts extensive datasets including ATSR-1 and ATSR-2 products, commercial satellite imagery, and data from various airborne sensors like LiDAR and CASI. The archive facilitates access to vital climate change research inputs, offers self-service options via FTP and HTTP, and maintains an 80 Terabyte structure with searchable metadata and preview images. For further assistance, contact NEODC or ESA support.
