Roadmap on the use of ARISE data for weather and climate in Europe

PSM Smets, LG Evers, AJ Charlton-Perez, CF Lee, G Harrison

This report summarizes the current abilities of the ARISE network, focussing on the use of ARISE data for weather and climate monitoring in Europe, now, and within the next 10 to 20 years. Based on this outcome, and future needs, a roadmap is proposed to enlighten the ARISE impact and implementation for weather and climate monitoring including potential areas of work.

ARISE has clearly demonstrated that it has the potential to fill important gaps for numerical weather prediction to improve modelling of weather and climate. Potential is shown that ARISE techniques can provide accurate measurements where GCMs do not typically assimilate data. High-­‐quality unbiased observations are of great importance. Idealized experiments have indicated that global coverage of stratospheric observations results in a larger forecast skill improvement compared to regional nudging.

Key actions are proposed towards the implementation of ARISE for weather and climate monitoring in the next 10 to 20 years. Assimilation of new observations requires a long pathway. Therefore, different steps are listed that lead to both short-­‐ and long-­‐term impacts.
