South Florida's Cloud-Aerosol-Rain Observatory: CAROb

Saharan dust transport across the Atlantic basin to the western hemisphere has intrigued researchers for decades. Its large-scale coverage implies far-flung radiative impacts while dust deposition can influence the biogeochemistry of both ocean and land. Dust is often present over the entire southeastern United States during the summer. Miami has a long history of dust research begun under Dr. Joseph Prospero, including dust filter sampling (see 10.1175/BAMS-D-18-0083.1 for a recent update), micropulse lidar measurements that include polarization, the sun photometers that are part of the Aerosol Robotic Network (Key Biscayne1, Key Biscayne2), and more detailed characterization of aerosol composition by Dr. Cassandra Gaston. A complete library of daily lidar imagery is available (please let me know if you make extensive use of these). See below for today’s GEOS-5 dust forecast and lidar imagery, with cloud condensation nuclei concentration information temporarily unavailable. These complement today's clouds and precipitation.
