Assessment of snowfall accumulation underestimation by tipping bucket gauges in the Spanish operational network

Description: Within the framework of the World Meteorological Organization Solid Precipitation Intercomparison Experiment (WMO-SPICE), the Thies tipping bucket precipitation gauge was assessed against the SPICE reference configuration at the Formigal–Sarrios test site located in the Pyrenees mountain range of Sp...

Observations and WRF simulations of fog events at the Spanish Northern Plateau

Description: The prediction of fogs is one of the processes not well reproduced by the Numerical Weather Prediction (NWP) models. In particular, the role of turbulence in the formation or dissipation of fogs is one of the physical processed not well understood, and therefore, not well parameterized by the NWP mo...

Speciation of organic aerosols in the Saharan Air Layer and in the free troposphere westerlies

Description: Speciation of organic aerosol was performed in the westerlies and in the Saharan Air Layer, where biogenic secondary organic aerosol (oxidation of isoprene and alpha-pinene) and primary combustion compounds (hopanes and PAHs) were observed. In the Saharan Air Layer, species (saccharides) linked to s...

Analysis of single-Alter-shielded and unshielded measurements of mixed and solid precipitation from WMO-SPICE

Description: Precipitation measurements were combined from eight separate precipitation testbeds to create multi-site transfer functions for the correction of unshielded and single-Alter-shielded precipitation gauge measurements. Site-specific errors and more universally applicable corrections were created from ...

Saharan and arabian dust aerosols: a comparative case study of lidar ratio

Description: El volumen 119 de 2016 de la revista EPJ Web of Conferences recoge las ponencias del 27th International Laser Radar Conference (ILRC 27) , This work presents a first comparative study of the Lidar Ratio (LR) values obtained for dust particles in two singular dust-influenced regions: the Canary Island...

Two simulated annealing optimization schemas for rational bézier curve fitting in the presence of noise

Description: Fitting curves to noisy data points is a difficult problem arising in many scientific and industrial domains. Although polynomial functions are usually applied to this task, there are many shapes that cannot be properly fitted by using this approach. In this paper, we tackle this issue by using rati...

MEDEX: a general overview

Description: The general objective of the international MEDiterranean EXperiment (MEDEX) was the better understanding and forecasting of cyclones that produce high impact weather in the Mediterranean. This paper reviews the motivation and foundation of MEDEX, the gestation, history and organisation of the projec...

Operational considerations to improve total ozone measurements with a Microtops II ozone monitor

Description: A Microtops II "ozone monitor" with UV channels centered at 305.5, 312.5, and 320 nm has been used routinely in six experimental campaigns carried out in several geographic locations and seasons, covering latitudes from 35 to 68° N during the last ten years (2001–2011). The total ozone content is re...

Preliminary results of the Social Impact Research Group of MEDEX: the request database (2000–2002) of two Meteorological Services

Description: One of the aims of the MEDEX project is to improve the knowledge of high-impact weather events in the Mediterranean. According to the guidelines of this project, a pilot study was carried out in two regions of Spain (the Balearic Islands and Catalonia) by the Social Impact Research group of MEDEX. T...

Lidar ratio derived for pure dust aerosols: multi-year micro pulse lidar observations in a Saharan dust-influenced region

Description: El volumen 119 de 2016 de la revista EPJ Web of Conferences recoge las ponencias del 27th International Laser Radar Conference (ILRC 27) , A seasonal distribution of the Lidar Ratio (LR, extinction-to-backscattering coefficient ratio) for pure Saharan dust particles has been achieved. Simultaneous MP...
