High-resolution thermal Earth Observation (EO) has been identified as a major observational gap in our rapidly warming climate. Land-surface temperature is a key variable needed for understanding and adapting to climate variability, managing water resources sustainably for agricultural production, mitigating health stress during heatwaves, predicting droughts, monitoring coastal and inland waters and addressing natural hazards such as fires and volcanoes.
For actionable information, Land Surface Temperature has to be measured with both high-resolution, to monitor management units such as single fields, and at sufficient temporal frequency. These requirements have been recognized by policy makers and international space agencies resulting in the preparation of a range of high-resolution thermal missions including TRISHNA (CNES/ISRO), SBG-Thermal (NASA/ASI) and LSTM (ESA/EC) to be launched in coming years. The ECOSTRESS mission (NASA) is providing excellent precursor data for these upcoming missions. Further there is an increasing interest of New Space initiatives preparing for smallsat missions and constellations for thermal observations with similar resolution.
Building on the ongoing cooperation between the space agencies, the main objective of this Workshop is to prepare for the availability of high-resolution thermal observations, strengthen synergies among the upcoming missions and to establish priority areas for future projects (e.g., the ESA Sentinel User Preparation initiative).
