Publikováno v: Atmospheric Research. 183:151-165

Cirrus (Ci) cloud properties can change significantly from place to place over the globe as a result of weather processes, reflecting their likely different radiative and climate implications. In this work Cirrus clouds (Ci) features observed in late

Impact evaluation of potential volcanic plumes over Spain

Autor: M.D. Valentí – Pía, José Antonio Adame, Manuel Gil-Ojeda

Publikováno v: Atmospheric Research. 160:39-49

The volcanic ash transport to Spain has been investigated as a part of a broader scale forecast system. Based on a double criterion, distance and eruptive history, four volcanic areas potentially affecting Spain have been investigated: Azores Islands

Publikováno v: Quarterly Journal of the Royal Meteorological Society. 141:2700-2707

A study has been carried out to assess the discrepancies between computed and observed aerosol scattering and backscattering properties in the atmosphere. The goals were: (i) to analyse the uncertainty associated with computed optical properties when

Long-path averaged mixing ratios of O3 and NO2 in the free troposphere from mountain MAX-DOAS

Autor: Manuel Gil-Ojeda, Y. González, Olga Puentedura, Emilio Cuevas, Laura Gómez, Mónica Navarro-Comas

Publikováno v: Atmospheric Measurement Techniques. 7:3373-3386

A new approximation is proposed to estimate O3 and NO2 mixing ratios in the northern subtropical free troposphere (FT). The proposed method uses O4 slant column densities (SCDs) at horizontal and near-zenith geometries to estimate a station-level dif
