Hurricane Hunter Integration Begins!

July 14th, 2014 by Luke Ziemba

Welcome to the LARGE (Langley Aerosol Research Group Experiment) blog.  We are a group of scientists at NASA Langley Research Center in Hampton, VA who study the chemical, optical, and microphysical properties of atmospheric aerosols and their effects on climate and air quality.  We are involved in many exciting experiments with vastly different objectives and applications, but this blog will begin by focusing on a project this summer/fall to assess the distribution and impacts of aerosols on hurricanes.


This project is just starting but the hurricane season is already underway with the passage of Hurricane Arthur, which made landfall on the Outer Banks of North Carolina on July 4, 2014.  Our work began the following week with installation of our instrumentation aboard the NOAA WP-3D aircraft known as “Kermit” (the other operational WP-3D aircraft is called “Miss Piggy”).  Operating scientific instrumentation aboard airplanes requires a lot of planning and adherence to strict guidelines to ensure flight safety and collection of high-quality data.  Since we make measurements in-situ (by bringing ambient air inside the aircraft cabin), our goal is to design a system that routes aerosols into the cabin and to our instruments without losing particles along the way.  This involves a complex web of tubing, fittings, and cabling shown below.

We still have work to do to complete our instrument integration, especially to install an aerosol inlet on the aircraft.  This will be completed soon and we will be poised to participate in the next hurricane flights!  Check back later for more details about our instrumentation, science objectives, and pictures from inside the next Atlantic hurricane…
