The overarching motivation for this session is the need for better understanding of in-situ measurements and satellite observations to quantify surface temperature (ST). The term "surface temperature" encompasses several distinct temperatures that differently characterize even a single place and time on Earth’s surface, as well as encompassing different domains of Earth’s surface (surface air, sea, land, lakes and ice). Different surface temperatures play inter-connected yet distinct roles in the Earth’s surface system, and are observed with different complementary techniques.

There is a clear need and appetite to improve the interaction of scientists across the in-situ/satellite 'divide' and across all domains of Earth's surface. This will accelerate progress in improving the quality of individual observations and the mutual exploitation of different observing systems over a range of applications.

This session invites contributions that emphasize sharing knowledge and make connections across different domains and sub-disciplines. They can include, but are not limited to, topics like:

* How to improve remote sensing of ST in different environments
* Challenges from changes of in-situ observing networks over time
* Current understanding of how different types of ST inter-­relate
* Nature of errors and uncertainties in ST observations
* Mutual/integrated quality control between satellite and in-situ observing systems.
* What do users of surface temperature data require in practical applications (like environmental or health sciences)?

Note that our session will be one of the innovative PICO sessions and there will not be the traditional split between oral presentations and poster session. For more details on the format, please see the EGU website; the convener is also happy to answer questions and support presenters.
