Table 2. The table shows which type of data would be available during the different phases of
a volcano reactivation timeline. Which type of products would be produced according to the
data and the usage of these products is also reported as function of time.
In this representation a long-term hazard assessment evolves into a short-term hazard assess-
ment and possibly even further

are presented in Table 5. A number of observations stand out:
1. In total 15 robust elements were identied. This was more than expected beforehand, given the many factors (elements,
connections, trajectories) distinguishing different exploratory scenarios.
2. The overall list covers a variety of sectors, actors, and factors. The overall list shows a broad set of highly integrated factors, actors

In Chapter 3 we focus on the following monthly averages: Near-surface 2 meter temperature
(TAS), total precipitation (TP), and sea ice cover (SI). In Chapter 4 we add surface air
pressure (PSL) and snow cover thickness (SNCT). The following daily fields will be studied
as well: Near-surface wind speeds, (U and V sfcWind), maximum near-surface 2 meter
temperature (TASMAX), minimum mean-surface 2 meter
