— A study of the melting cycle of snow was carried out by combining microwave active and passive measurements with meteorological data and snow modelling. The experiment took place in the eastern Italian Alps from mid February to late May 2003. Brightness temperature at C-, Ku-and Ka-bands (vertical and horizontal polarizations) and backscattering(More)
—A study of the melting cycle of snow was carried out by using ground-based microwave radiometers, which operated continuously 24 h/day from late March to mid-May in 2002 and from mid-February to early May in 2003. The experiment took place on the eastern Italian Alps and included micrometeorological and conventional snow measurements as well. The(More)
This introductory paper presents and summarises recent research on meteorological and hydrological aspects of floods in the Alps. The research activities were part of the international research project RAPHAEL (Runoff and Atmospheric Processes for flood HAzard forEcasting and controL) together with experiments within the Special Observing Period-SOP(More)
Results of the Mesoscale Alpine Programme provide some answers to basic scientific questions of hydrological relevance posed in its scientific plan i.e: 1. verify the forecasting capabilities of a hydrological flood model, forced by the special measurements or coupled with advanced mesoscale atmospheric prediction models; 2. assess the role of the water(More)
River floods are influenced by factors such as the duration, intensity and spacial distribution of precipitation and the land-use as well as the morphological characteristics of the river basin. While the characteristics of the precipitation are tied to the climatology of the region and can change only over the long term, anthropogenic land use changes(More)
Based on a high-quality dataset of 713 daily precipitation series, changes in daily precipitation events during 1960–2013 were observed in China's ten largest river basins. Specifically, the amount of precipitation in four categories defined by fixed thresholds and their proportion on total precipitation were analyzed on annual and seasonal time scales.(More)
The space time image velocimetry (STIV) technique is presented and shown to be a useful tool for extracting river flow information non-intrusively simply by taking surface video images. This technique is applied to measure surface velocity distributions on the Uono River on Honshu Island, Japan. At the site, various measurement methods such as a radio-wave(More)
Pan measurement is a reliable and efficient method for indicating the evaporative demand of the atmosphere. There are several types of pan evaporimeters worldwide, and the estimation of the conversion coefficients (K p) between them is necessary in hydrologic research. In China, E601B pans were installed at all meteorological stations beginning in 1998.(More)
One of the most ambitious ongoing research project in glacier monitoring is the GLIMS (Global Land Ice Monitoring from Space) Project, coordinated by the USGS. The main objective of this international project is to establish a new global inventory of land ice based on remote sensing data (mainly on ASTER images). The research team of the Department of Civil(More)
