A fuzzy logic technique for identifying nonprecipitating echoes in radar scans
(American Meteorological Society, 2006-09)
Article
Open AccessBecause echoes caused by nonmeteorological targets significantly affect radar scans, contaminated bins must be identified and eliminated before precipitation can be quantitatively estimated from radar measurements. Under ... -
A methodology for attenuation correction based on the minimization of a cost function
(American Meteorological Society, 2003)
Conference report
Open Access -
A quality control procedure for long-term series of daily precipitation data in a semiarid environment
(2022-05-25)
Article
Open AccessThe availability of quality precipitation records in the current climate situation is of great importance in the scientifctechnical feld but also for the public institutions that manage the meteorological networks. This ... -
A simple scaling analysis of rainfall in Andalusia (Spain) under different precipitation regimes
(2022-04-16)
Article
Open AccessA simple scaling analysis was performed in Andalusia (Spain) using daily records from 377 selected stations covering the temporal period between 1870 and 2018. Since Andalusia is a region of considerable climatic variety, ... -
A study of the error covariance matrix of radar rainfall estimates in stratiform rain
(2008-12)
Article
Open AccessThe contribution of various physical sources of uncertainty affecting radar rainfall estimates at the ground is quantified toward deriving and understanding the error covariance matrix of these estimates. The focus here ... -

Análisis espectral del contenido de agua en suelos no saturados
(Universitat Politècnica de Catalunya, 2023-07-20)
Master thesis
Open AccessLa cantidad de agua presente en los suelos no saturados experimenta variaciones significativas a lo largo del tiempo debido. Esta variación obedece a los flujos entrantes y salientes, ya sea por escorrentía, lluvias o ... -
Blending of radar and gauge rainfall measurements: a preliminary analysis of the impact of radar errors
(International Association of Hydrological Sciences (IAHS), 2011)
Conference report
Restricted access - publisher's policySeveral methodologies have been proposed to combine radar and raingauge measurements with the aim of generating improved quantitative precipitation estimates (QPEs). These methods are based on interpolating point raingauge ... -

Comparing precision lysimeter rainfall measurements against rain gauges in a coastal dune belt, Spain
(Elsevier, 2020-12)
Article
Open AccessPrecipitation measurements are performed mostly by simple automatic rain gauges installed at a certain level above the ground surface, but these methods are often affected by significant measurement errors due to the ... -
EUREC4A's Maria S. Merian ship-based cloud and micro rain radar observations of clouds and precipitation
(2022-01-10)
Article
Open AccessAs part of the EUREC4A field campaign, the research vessel Maria S. Merian probed an oceanic region between 6° N and 13.8° N and 51° W to 60° W for approximately 32 days. Trade wind cumulus clouds were sampled in the ... -
Experimental campaign for the characterization of precipitation in a complex terrain site using high resolution observations
(Institute of Physics (IOP), 2024-06-01)
Article
Open AccessPrecipitation has an effect on wind power at several levels. It affects the wind current, blade status, wake development and power production. Power production is affected by the harmful effect of precipitation on the ... -
Fire monitoring with satellite and UAV imagery
(Universitat Politècnica de Catalunya, 2016)
Master thesis (pre-Bologna period)
Open AccessWildfires are of major concern now days because, even though they have also a natural role, they have negative impacts in environmental, economic and social terms. The main purposes of this project are the study, combination, ... -
Hydrological application of radar rainfall nowcasting in the Netherlands
(Elsevier, 2020-03)
Article
Open AccessAccurate and robust short-term rainfall forecasts (nowcasts) are useful in operational flood forecasting. However, the high temporal and spatial variability of rainfall fields make rainfall nowcasting a challenging endeavour. ... -
Hydrological evaluation of a nowcasting technique applied to flood forecasting
(American Meteorological Society, 2003)
Conference report
Open Access -
Hydrological validation of a radar-based nowcasting technique
(2005-08)
Article
Open AccessNowcasting precipitation is a key element in the anticipation of floods in warning systems. In this framework, weather radars are very useful because of the high resolution of their measurements both in time and space. ... -
