Progress on CASEarth Satellite Development

CASEarth satellite is the first space Earth science satellite produced by the Chinese Academy of Sciences. The satellite has three payloads:high-definition Thermal Infrared Spectrometer (TIS), high-definition Glimmer Imager for Urbanization (GIU), and high-definition Multispectral Imager for Inshore (MII). These payloads are used to explore the urbanization level and residential layout, the coastal ecosystem, and new methods and approaches of environmental detection during night-time and even under conditions of polar aurora and provide scientific evidence for the refined depiction of human traces. The CASEarth satellite can provide space observation data for A Project on Big Earth Data Science Engineering as well as scientific and application studies inside and outside China.
