Ambient air pumped for an hour into a ~10 litre aluminium container, thereby collecting a compressed sample of great volume, done weekly or semi-monthly depending on season. Various components are analysed, investigating the stability of atmospheric composition.

consciously intended to reduce the risk of glossing over
potential key variables, especially since the empirical base
for AIWM is yet rather weak, and we cannot a priori justify
which variables should be in or out.
A framework for assessing responsiveness
to floods and droughts
A second analytical framework, independent from the first
one, has been developed for assessing

At 13:00 today, 26 February, the discharge of Hvítá at Fremstaver, in the northern part of the catchment, was 520 cubic metres per second. It will take floodwater in this region several hours to drain south, so maximum discharge will not be reached

where concerns over data quality are greater. Multi-decadal vari-
ability and the quality of the tropical cyclone records prior to routine
satellite observations in about 1970 complicate the detection of long-
term trends in tropical cyclone activity. {WGI 3.8, SPM}

Current velocity: The RSAM velocity of the most recent minute must exceed a
specified, configurable threshold amplitude in micrometers per second (m/s). If the
most recent RSAM value exceeds the amplitude threshold, the average velocity of
ground movement is great enough to warrant eruptive volcanic activity.

widespread adoption of participatory modelling by resource managers in the water sector,
concluding that this potential is low. It proposes recommendations as to how the potential
