The coordinated multi-sensor, multi-platform ARCTAS fire plume study on June 30, 2008
Abstract
The scientific goals of the 2008 Arctic Research of the Composition of the Troposphere from Aircraft and Satellites (ARCTAS) field campaign included the study of biomass burning emissions through the synergistic use of observations using a wide variety of experimental techniques (e.g., in situ, radiometric, active remote sensing) from multiple platforms (ground, airborne, satellite). The utility of this approach lies in the careful coordination of all platforms to allow meaningful comparison and useful combination of the data from all instruments. In this paper we report on the multi-platform fire plume study on June 30, 2008. A portion of the flight track of the NASA P-3 aircraft carrying a suite of in situ aerosol and radiometric instruments was coordinated to coincide in space and time with the flight track of the B-200 aircraft carrying a high spectral resolution lidar (HSRL) and the GISS Research Scanning Polarimeter (RSP). We will use the P-3 radiometric instrumentation and apply different techniques to derive aerosol radiative forcing efficiency, absorption aerosol optical depth (AAOD) and single scattering albedo, and compare them to the P-3 in situ observations. We will then compare the P-3 estimates of spectral aerosol extinction, aerosol optical depth, and aerosol absorption, to those retrieved from the HSRL and RSP remote sensing suite on the B-200. In the next step of our analysis we will compare the suborbital observations of aerosol radiative properties to estimates from coincident MODIS, CALIPSO and OMI measurements and show how these satellites provide different estimates for some quantities based on sensor spatial resolution and scene heterogeneity alone. Finally, we will use all measurements to derive a set of aerosol radiative properties sufficient for aerosol direct radiative effect calculations and compare these calculations to CERES flux measurements.
