Accessing Airborne and Field Campaign Data with the Sub-Orbital Order Tool

Suborbital campaigns serve as a key component of the integrated observing system of the atmosphere by linking satellite observations and surface measurements, as well as probing atmospheric phenomena critical to climate change and air quality issues. These suborbital campaigns often deploy many instruments on different platforms, including aircraft, ships, sondes, …

Characterization of Particle Size Distribution Uncertainties using SAGE II and SAGE III/ISS Extinction Spectra

A new algorithm was developed to infer particle size distribution parameters from the Stratospheric Aerosol and Gas Experiment II (SAGE II) and SAGE III on the International Space Station (SAGE III/ISS) extinction spectra using a lookup table (LUT) approach. Here, the SAGE-based extinction ratios were matched to LUT values and, …

Exploring the Impact of the 2020 West Coast Wildfires

On September 9, 2020, the fire known as 'The August Complex' became the largest wildfire in California’s history. The fire started as a series of separate fires ignited by lightning strikes. Fueled by periods of drought, record-breaking high temperatures, and drier-than-usual air, the individual fires combined into a single blaze …

Understanding the North American Monsoon Anticyclone with DCOTSS

Each summer, the North American Monsoon Anticyclone (NAMA) dominates the circulation of the North-Western Hemisphere and acts to partially confine and isolate air from the surrounding atmosphere. Because of NAMA, strong convective storms develop over North America and overshoot the tropopause into the lower stratosphere. These storms carry water and …
