VolMIP contributes to CMIP6 as endorsed MIP (World Climate Research Program, WCRP).
Eleven climate modeling groups have committed to perform all our core (Tier 1) experiments.
VolMIP is central to the three broad CMIP questions:
. How does the Earth system respond to external forcing?
. What are the origins and consequences of systematic model biases?
. How can we assess future climate changes given climate variability, predictability and uncertainties in scenarios?
VolMIP is closely linked to the WCRP Grand Challenge on:
. "Clouds, circulation and climate sensitivity", in particular through improved characterization of volcanic forcing and
improved understanding of how the hydrological cycle and the large-scale circulation respond to volcanic forcing. VolMIP
further contributes to the initiative on leveraging the past record through planned experiments describing the climate
response to historical eruptions that are not (or not sufficiently) covered by CMIP6-DECK, -historical or other MIPs. VolMIP
will contribute towards more reliable models through improved understanding of how model biases affect the response to a
well-defined volcanic forcing.
. "Climate extremes" and "Regional climate information", in particular through a more systematical assessment of regional
climate variability - and associated predictability and prediction - during periods of strong volcanic forcing at both
intraseasonal-to-seasonal (e.g., post-eruption Northern Hemisphere's winter warming) and interannual-to-decadal (e.g.,
post-eruption delayed winter warming) time scales.
. "Water Availability", in particular through the assessment of how strong volcanic eruptions affect the monsoon systems
and the occurrence of extensive and prolonged droughts.
. "CLIC and Cryosphere", in particular concerning the onset of volcanically forced long-term feedbacks involving the
cryosphere which is suggested by recent studies (e.g., Miller et al., 2014, Berdahl and Robock, 2013; Zanchettin et al.,
2014). VolMIP encourages the interested modeling community to discuss sensitivity experiments focused on the climatic
effects of aspects related to tephra deposition.
