A new study, published in the EGU’s open access journal Earth System Dynamics, reports on concentratio ...[Read More]

Imaggeo on Mondays: Aerosols over Hurricane Irene

The red-yellow areas in the image represent regions with high aerosol concentration that have been swept upwards in convective clouds and the blue areas are clean regions. The aerosols enter Irene along rain bands, before being wrapped into the centre ...[Read More]
