New Precipitation Value-Added Product Released for Laser Disdrometers
A new precipitation value-added product (VAP) for the Atmospheric Radiation Measurement (ARM) user facility provides quality-controlled disdrometer measurements of drop size distributions (DSDs), rain rates, and polarimetric radar-equivalent quantities. The Laser Disdrometer VAP for Quality-Controlled Measurements, using PyDSD (LDQUANTS) capitalizes on laser disdrometer measurements from ARM fixed observatories and mobile facility deployments. DSD measurements from…

SHEBA: Still Serving Science
An arctic field campaign in the late 1990s set the stage for present-day research investigating shrinking ice cover, warming temperatures, and other changes In May 1998, Bonnie Light, then a graduate student in atmospheric science at the University of Washington, climbed into a Twin Otter aircraft at an airfield in northern Alaska. It was the…
