Four Years of Atmospheric Boundary Layer Height Retrievals Using COSMIC-2 Satel...
Garnés-Morales, Ginés; Costa, Maria João; Bravo-Aranda, Juan Antonio; Granados-Muñoz, Maria José; Salgueiro, Vanda; Abril-Gago, JesusThis work aimed to study the atmospheric boundary layer height (ABLH) from COSMIC-2 refractivity data, endeavoring to refine existing ABLH detection algorithms and scrutinize the resulting spatial and seasonal distributions. Through validation analyses involving different ground-based methodologies (involving data from lidar, ceilometer, microwave radiometers, and radiosondes), the optimal ABLH determination re...
Fine and coarse dust radiative impact during an intense Saharan dust outbreak o...
López-Cayuela, M.A.; Córdoba-Jabonero, C.; Sicard, M.; Abril-Gago, J.; Salgueiro, Vanda; Comerón, A.; Granados-Muñoz, M.J.; Costa, Maria JoãoMineral dust has a key role in the Earth’s radiative balance, and it has become significant over the Iberian Peninsula (IP), where Saharan dust outbreaks have seemed to increase in frequency and intensity. This study quantifies the dust direct radiative effect (DRE) in the short-wave range (SW) during an intense persistent springtime dust episode over the IP. In particular, the vertical distribution of dust opt...

Atmospheric boundary layer height from ground-based remote sensing: a review of...
Kotthaus, Simone; Bravo-Aranda, Juan Antonio; Collaud Coen, Martine; Guerrero-Rascado, Juan Luis; Costa, Maria João; Cimini, Domenico; O'Connor, EwanThe atmospheric boundary layer (ABL) defines the volume of air adjacent to the Earth's surface for the dilution of heat, moisture, and trace substances. Quantitative knowledge on the temporal and spatial variations in the heights of the ABL and its sub-layers is still scarce, despite their importance for a series of applications (including, for example, air quality, numerical weather prediction, greenhouse gas ...
Microwave radiometer, sun-photometer and GNSS multi-comparison of integrated wa...
Vaquero-Martínez, Javier; Antón, Manuel; Costa, Maria João; Bortoli, Daniele; Navas-Guzmán, Francisco; Alados-Arboledas, LucasThis work presents a comparison of integrated water vapor (IWV) data recorded from microwave radiometer (MWR) and sun-photometer (SP) using global navigation satellite system (GNSS) IWV as reference in five mid-latitude sites of Portugal and Spain (2003–2021). A very high correlation is obtained for both instruments (R2 between 0.94 and 0.98), although, while MWR shows a wet bias, SP exhibits a dry one. In addi...
Characterization of Tajogaite volcanic plumes detected over the Iberian Peninsu...
Salgueiro, Vanda; Guerrero-Rascado, Juan Luis; Costa, Maria João; Román, Roberto; Cazorla, Alberto; Serrano, Antonio; Molero, Francisco; Sicard, MichaelThree volcanic plumes were detected during the Tajogaite volcano eruptive activity (Canary Islands, Spain, September–December 2021) over the Iberian Peninsula. The spatiotemporal evolution of these events is characterised by combining passive satellite remote sensing and ground-based lidar and sun-photometer systems. The inversion algorithm GRASP is used with a suite of ground-based remote sensing instruments s...
Vertical characterization of fine and coarse dust particles during an intense S...
López-Cayuela, Maria Ángeles; Córdoba-Jabonero, Carmen; Bermejo-Pantaleón, D.; Sicard, Michael; Salgueiro, Vanda; Molero, FranciscoAn intense and long-lasting Saharan dust outbreak crossed the Iberian Peninsula (IP) from the southwest (SW) to the northeast (NE) from 25 March until 7 April 2021. This work aims to assess the optical and mass contribution of both fine and coarse dust particles along their transport. Five Iberian lidar stations were monitoring the transport and evolution of the Saharan dust particles, i.e. El Arenosillo/Huelva...
Validation of the TROPOMI/S5P aerosol layer height using EARLINET lidars
Michailidis, Konstantinos; Koukouli, Maria-Elissavet; Balis, Dimitris; Veefkind, J. Pepijn; de Graaf, Martin; Mona, Lucia; Papagianopoulos, NikolaosThe purpose of this study is to investigate the ability of the Sentinel-5P TROPOspheric Monitoring Instrument (TROPOMI) to derive accurate geometrical features of lofted aerosol layers, selecting the Mediterranean Basin as the study area. Comparisons with ground-based correlative measurements constitute a key component in the validation of passive and active satellite aerosol products. For this purpose, we use ...
