Third Joint GSICS/IVOS Lunar Calibration Workshop - Darmstadt, Germany - 16-19 November 2020

In order to promote further communication and collaboration on lunar calibration, the Third Joint GSICS/CEOS-IVOS Lunar Calibration Workshop was foreseen to be hosted by EUMETSAT in Darmstadt, Germany. Due to the situation with Covid-19, virtual sessions were oganised between the 16th and the 19th of November 2020.

The main objectives of the Third Lunar Calibration Workshop were to share knowledge and expertise on:

• The latest dedicated space-based, ground-based and airborne lunar observation campaigns, that can help refine the current lunar calibration reference.
• The preparation of lunar irradiance measurements from observations by the instruments to be monitored.
• New developments of lunar irradiance models, and to define a framework for inter-comparing the performances of those models over a common set of geometrical and observation conditions.
• Alternative applications of lunar observations for calibration purposes, for instance in the microwave domain, or post-launch assessments, such as geometric and MTF characterization.

The web meetings addressed the following topics:

• Measurements and Moon observations: towards SI traceability
• Lunar calibration and model development
• Instrument monitoring using lunar calibration
• Thermal Infrared and microwave remote sensing and lunar observation
• Alternative applications of lunar observation, including geometric and MTF post-launch characterisation

Two complementary activities were also planned:

• Lunar irradiance model inter-comparison (coordinated by S. Wagner – EUMETSAT and T. Stone - USGS);
• Towards a GSICS recommended approach for MTF post-launch characterisation using lunar imagery (coordinated by X. Wu - NOAA).

However, those two specific activities were not discussed in depth during the four-day event due to the limited time of the virtual sessions. Follow-on meetings are foreseen for 2021.
