How a mesoscale cyclonic vortex over Sahara leads to a dust outbreak in South-western Iberia

Couto FT, Cardoso EHC, Costa MJ, Salgado R, Guerrero-Rascado JL, Salgueiro V (2021) The study focused on an exceptional desert dust outbreak episode, in particular on the role of atmospheric circulation transporting high amounts of dust toward Portugal in February 2017. In order to assess the atmospheric conditions behind the mineral dust layer observed in […]

Guidance for the Integrated Use of Hydrological, Geochemical, and Isotopic Tools in Mining Operations

Wolkersdorfer, C., Nordstrom, D.K., Beckie, R.D. et al.  This paper summarizes international state-of-the-art applications and opportunities for employing and deploying hydrological, geochemical, and isotopic tools in an integrated manner for investigations of mining operations. It is intended to aid formulation of more integrated approaches for evaluating the overall sustainability of mining projects. The focus is particularly […]

A Discussion on the Quantification and Classification of Geodiversity Indices Based on GIS Methodological Tests

Gonçalves, J., Mansur, K., Santos, D. et al.  Quantitative assessment methods are attaining special attention in geodiversity research. Procedures to map geodiversity indices have been proposed by several authors though there is no consensus on how to best apply and replicate them in diverse areas. A contribution to the quantitative mapping of geodiversity using GIS tools […]

Improved ECMWF forecasts of direct normal irradiance: A tool for better operational strategies in concentrating solar power plants

Francisco M. Lopes, Ricardo Conceição, Hugo G. Silva, Rui Salgado, Manuel Collares-Pereira To contribute for improved operational strategies of concentrating solar power plants with accurate forecasts of direct normal irradiance, this work describes the use of several post-processing methods on numerical weather prediction. Focus is given to a multivariate regression model that uses measured irradiance […]
