Effect of Atmospheric Dust on Ice Cloud Formation Confirmed
It is known that the proportion of ice-topped clouds depends on dust particles in the cloud that act as nuclei for ice crystal formation............

Enhancement of OVA-induced murine lung eosinophilia by co-exposure to contamination levels of #LPS in Asian sand #dust and heated dust
Yahao Ren, et al.
Published: 2014 Jun 9"A previous study has shown that the aggravation of Asian sand dust (ASD) on ovalbumin (OVA)-induced lung eosinphilia was more severe in lipopolysaccharide (LPS)-rich ASD than in SiO2-rich ASD. Therefore, the effects of different LPS contamination levels in ASD on the aggravation of OVA-induced lung eosinophilia were investigated in the present study.
Conclusions:
"This study demonstrates that LPS contamination in ASD aggravates allergic lung inflammation in the presence of OVA and H-ASD. The aggravation of the allergic lung inflammation by LPS may be caused through the TLR4-dependent signaling pathway. The results of the current study indicate that the exposure to ASD with LPS may be a significant risk factor for adult and child #asthma. The hazardous effects of #MineralDust and #biogenic agents on human respiratory disease are an increasing public concern. Atmospheric exposure to #bacteria, fungi and virus, and silica-carrying particulate matters may influence human respiratory health on a world-wide scale."

If you are interested in (passive) remote sensing of dust storms and attending #EGU24, you might be interested in my talk on Thursday at 17:50 (Room E2). If you are planning to attend another session, hit me up, and let's have a chat during the next few days.
We used an off-the-shelf machine-learning code and existing datasets for training to restore the spatial extent of dust plumes, which are hidden underneath clouds.

#Dust is a powerful force in the #CriticalZone. It moves chemicals, good and bad, over long distances. In this collection of #timelapse videos the power of the collective force of #MineralDust is clear.
