| Zusammenfassung |
| During the airborne research mission ASTAR 2004 (Arctic Study of
Tropospheric Aerosols, Clouds and Radiation) performed over the island of
Svalbard in the Arctic a constant-temperature hot-wire Nevzorov Probe
designed for aircraft measurements, has been used onboard the aircraft POLAR
2. The Nevzorov probe measured liquid water (LWC) and total condensed water
content (TWC) in supercooled liquid and partly mixed phase clouds,
respectively. As for other hotwire probes the calculation of LWC and/or TWC
(and thus the ice water content IWC) has to take into account the collection
efficiencies of the two separate sensors for LWC and TWC which both react
differently with respect to cloud phase and what is even more difficult to
quantify with respect to the size of ice and liquid cloud particles. The
study demonstrates that during pure liquid cloud sequences the ASTAR data
set of the Nevzorov probe allowed to improve the quantification of the
collection efficiency, particularly of the LWC probe part with respect to
water. The improved quantification of liquid water content should lead to
improved retrievals of IWC content. Simultaneous retrievals of LWC and IWC
are correlated with the asymmetry factor derived from the Polar Nephelometer
instrument. |
