TRACER Cell Tracking Data Shed Light on Convective Evolution
One challenge in analyzing convective cell properties is trying to observe the quick evolution of individual convective cells, which might not be captured by conventional radar volume scans that take about 5 to 7 minutes. Aiming to enhance understanding of the links between convective cloud kinematic and microphysical processes as well as cloud life cycles,…

BAMS Features ARM Mountain Hydrology Campaign
New paper highlights initial results from 21-month SAIL study in Colorado watershed Mountainous watersheds provide most of the world’s freshwater, but they are complex, under-measured systems that have proven difficult to understand and model. New approaches to data collection and scientific research in high-altitude complex terrain are needed to better understand and predict how the…

Evaluate Aerosol Optical Depth Best Estimate Data Product
New data are available from the Aerosol Optical Depth Best Estimate value-added product (AODBE VAP), previously known as Quality Control Aerosol Optical Depth (QCAOD). The VAP was renamed to better describe the data product. AODBE combines individual AODs measured by four co-located instruments: two multifilter rotating shadowband radiometers, one normal incidence multifilter radiometer, and one…
