🚀 The BASTA system from @actris.bsky.social CCRES is now installed to calibrate our NEBULA and NEPHELE radars.
A key step to sharpen our cloud observations and advance #AtmosphericScience! 🌩️🌤️

Atardecer fresco y rojizo (posiblemente por el humo de los incendios de Canadá) desde el cordón dunar de Cortadura, en #Cádiz.
Ya empiezan a florecer las azucenas de mar (Pancratium maritimum) en nuestras costas.

🚨🚨 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.

🌍 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.

🛰️ 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.

Record heat and dry conditions helped stoke several large blazes in Manitoba, Ontario, and Minnesota.

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.

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.

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.

🌨️Tarde de nieve en el entorno del observatorio del Mojón del Trigo (#SierraNevada, 2610 msnm). El termómetro de nuestra estación meteorológica marca -0,3 ºC a esta hora.
#SNS #AGORA
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 #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.

Great to have Diego Loyola, the Director of the Atmospheric Processors Department at @dlr-en.bsky.social visit to #GFAT. He delivered a talk on satellite sensors and exchange opportunities in the context of #IISTA Unidad de Excelencia #deepAtmo project. A fantastic collaboration opportunity!

🏔️ Si quieres evitar la exposición al polen, #SierraNevada no es el mejor destino❗

🫒 Grandes masas de polen de olivo se desplazan a Sierra Nevada según investigadores #UGR. La causa, las corrientes de aire 🌬️

El cielo de Bucarest nos regala estos fenómenos de #halo (halo de 22º, parhelios, arco tangente superior y arco circuncenital) sobre un fondo de Cirrostratus.
Estamos en el ACTRIS-CARS Training Workshop para trabajar en el mantenimiento de nuestro lídar.

Exciting times! Our colleague Matheus is on a research stay at the Institute of Geophysics and Meteorology #UniCologne, developing an algorithm to process cloud radar data ☁️
This work will help cloud radar users to interpret cloud dynamics—improving weather and climate studies!

One year ago our cloud radar NEBULA arrived at @iista.bsky.social and we inaugurated the measurements with a rare hailstorm at Granada! @gfat.bsky.social #cloudwatch4science
