Aerosol type classification with machine learning techniques applied to multiwavelength lidar data from EARLINET Abstract. Aerosol typing is essential for understanding atmospheric composition and its impact on the climate. Lidar-based aerosol typing has been often addressed with manual classification using opti...

🚀 New paper out in Atmospheric Chemistry and Physics!

We present a machine learning approach for aerosol type classification using multiwavelength lidar data from the EARLINET network.

🚨🚨 A similar event is currently being observed over Granada! The image reveals an intense dust layer within the boundary layer, accompanied by a more widespread but less intense smoke presence extending throughout the entire atmospheric column.

Canada’s wildfire season begins Wildfire season has arrived in full force in Canada, prompting evacuation orders and alerts in several towns in British Columbia and Alberta due to the danger of uncontrolled blazes.Hazardous smoke fr...

🌍 The plume didn’t stop there and continued across the North Mediterranean, reaching Italy, the Balkans, Greece, and Turkey. This image by Copernicus Sentinel-3 corresponds to May 18, and a clear plume can be observed covering the whole Island of Sicily.

Fires Erupt in North American Forests Record heat and dry conditions helped stoke several large blazes in Manitoba, Ontario, and Minnesota.

🛰️ Satellite imagery tracks the aerosol plume back to central Canada (Manitoba) on May 13, coinciding with an intensification of wildfires in the area (earthobservatory.nasa.gov/images/15429...). The plume then crossed the Atlantic, reached the Canary Islands, and arrived over Europe by May 17.

Aerosol Optical Depth and Ångström Exponent measured by the Sun-photometer over Granada show a sharp increase in both aerosol load and AE values on May 17. This indicates a dominance of fine particles, likely from biomass burning given their abundance.

🚨 An unusually intense aerosol signal was detected over Granada by our ceilometer, peaking around 9 km above the city! Such strong signals are rare at this altitude and indicate the presence of an elevated aerosol layer.

With the combination of #GRASS and #GRAINS (GRAnada Ice Nuclearing particle Spectrometer) we can study the INPs concentration in the #atmosphere.
Stay tuned for results!

For the first time at #SNS station, we are sampling ice nucleating particles (INPs) with the use of #GRASS (GRAnada Samplying System).
INPs trigger the formation of ice crystals in #clouds.

SNS station (Mojón del Trigo Observatory, Sierra Nevada, 2610 m.a.s.l.) This station is one of the main facilities of the Andalusian Global ObseRvatory of the Atmosphere observational (AGORA) platform and provides information on aerosol, gases and clouds with in-situ instrumentation.

All set for the summer campaign at #SNS station (Mojón del Trigo Observatory, 2610 m a.s.l.) from #AGORA. This campaign is framed in the #NUCLEUS project, which aims to study the role of #aerosol particles in #cloud formation.

El observatorio del Mojón del Trigo, en Sierra Nevada, es la estación de alta montaña (SNS) que forma parte del Observatorio Global de la Atmósfera de Andalucía (AGORA). El Grupo de Física de la Atmósfera de la Universidad de Granada estudia las propiedades ópticas del aerosol atmosférico, las nubes y las precipitaciones con la variada instrumentación que opera en este edificio histórico.

The kick-off meeting of the #DeepAtmo (Deep Learning for Atmospheric Components Classification and Aerosol Typing using Remote Sensing Measurements) project took place this morning at @iista.bsky.social 📡👩‍🔬

Our colleagues Daniel Pérez Ramírez, Víctor Manuel Naval Hernández and Arlett Díaz Zurita.

The #GFAT was well represented at #EGU25, recently held in Vienna. Our colleagues Arlett Díaz, Víctor Naval and Daniel Pérez presented their work related to the characterization of the atmospheric #watervapor over Granada.
