On March 16, 2023 the Intergovernmental and Multistakeholder Advisory Group and Multidisciplinary Expert Scientific Advisory Group met to consider the following agenda items: • Roundtable introductions • Discussion on how the IMAG and MESAG can work together. On these agenda items, the meeting decided to ensure synergy and avoid conflicting guidance to the authors / co-chairs from the GEO-7 advisory bodies. To that effect the IMAG and MESAG agreed to: • To share information on the meeting schedules and workplans for IMAG and MESAG to plan for any matters that require policy and scientific guidance. • To hold calls between the IMAG and MESAG Bureaus as needed at semi- regular intervals to discuss key issues and any potential overlapping scientific and policy guidance and if deemed necessary by the respective Bureaus, exchange any draft guidance before it is issued. • To hold full IMAG and MESAG calls if deemed necessary by the respective Bureaus on matters where scientific and policy guidance are required from both GEO-7 advisory bodies.
