The following maps show the frequency
of occurrence of ISSRs on two pressure levels, 147 hPa, and 215 hPa, projected
onto world maps. The humidity data to obtain these figures stem from the
Microwave Limb Sounder (MLS). The
evaluation procedure and more details can be found in Spichtinger et al.
(2003, QJ paper).
Figure 1: Frequency of occurrence of icesupersaturated regions on the 147 hPa level.
Figure 2: Seasonal frequencies of
occurrence of ice supersaturated regions on the 147 hPa level.
Figure 3: Frequency of occurrence
of icesupersaturated regions on the 215 hPa level.
Figure 4: Seasonal frequencies of occurrence of ice supersaturated regions on the 215 hPa level.
