Zusammenfassung |
The important role played by ground-based microwave weather radars for the
monitoring of volcanic ash clouds has been recently demonstrated. The
potential of microwaves from satellite passive and ground-based active
sensors to estimate near-source volcanic ash cloud parameters has been also
proposed, though with little investigation of their synergy and the role of
the radar polarimetry. The goal of this work is to show the potentiality and
drawbacks of the X-band dual polarization (DPX) radar measurements through
the data acquired during the latest Grímsvötn volcanic eruptions
that took place in May 2011 in Iceland. The analysis is enriched by the
comparison between DPX data and the observations from the satellite Special
Sensor Microwave Imager/Sounder (SSMIS) and a C-band single polarization
(SPC) radar. SPC, DPX, and SSMIS instruments cover a large range of the
microwave spectrum, operating respectively at 5.4, 3.2, and 0.16–1.6 cm
wavelengths. |
