Short Name:


The GRIP Langley Aerosol Research Group Experiment (LARGE) dataset was collected by the Langley Aerosol Research Group Experiment (LARGE), which measures ultrafine aerosol number density, total and non-volatile aerosol number density, dry aerosol size distribution, total and submicron aerosol absorption coefficients, total and submicron aerosol scattering coefficients, and total scattering and hemispheric backscattering coefficients. Instruments used during LARGE derived aerosol size statistics (mode, number and mass mean diameters, etc.), aerosol surface area and mass loading, aerosol extinction, single scattering albedo, and angstrom coefficients. This dataset was collected during the Genesis and Rapid Intensification Processes (GRIP) experiment, which a NASA Earth science field experiment. The major goal was to better understand how tropical storms form and develop into major hurricanes. NASA used the DC-8 aircraft, the WB-57 aircraft and the Global Hawk Unmanned Airborne System (UAS), configured with a suite of in situ and remote sensing instruments that were used to observe and characterize the lifecycle of hurricanes. The GRIP LARGE dataset collected data over the Gulf of Mexico from August 6, 2010 to September 22, 2010.
