Background
 

Aerosol measurement observations from ground-based sun photometers and sun/sky radiometers have played a critical role in developing, reformulating and validating satellite algorithms to characterize aerosol optical depth, modal aerosol retrievals and single scattering albedo among other parameters.   New and improved algorithms are being developed for current and future satellite missions that will place a greater demand on the accuracy and fidelity of the ground-based measurements for validation, multi data set synergism and long-term climate research.  Heretofore satellite validation studies using sun and sky scanning spectral radiometer measurements such as AERONET have relied on point observations extrapolated to a two dimensional domain to compare to the satellite retrieval.  Additionally few of the ground-based remote sensing measurements have had a rigorous comparison or validation against other ground-based measurements particularly in situ observations of aerosol size and absorption.  DRAGON-SE Asia in combination with Seven SouthEast Asian Studies (7-SEAS) mission will provide a data set to address satellite validation and in situ comparisons.

 
Experimental Objectives (Top)
 
  • Characterize the temporal and spatial context of the local and regional SE Asian aerosol particles and optically-thin cloud regimes.
  • Investigate the three-dimensional urban aerosol plume structure and document variability relative to that observed in biomass source regions.
  • Provide state-of-the-art ground truth for aircraft and satellite remote sensing platforms.
 
Measurement Plan (Top)
 

The 7-SEAS mission deployments (Figure 1) of sun/sky radiometers will occur in Bangladesh, Indonesia, Malaysia, and Philippines from June 15 to at least October 1, 2012. These sites will augment those already deployed in the region in the countries of Indonesia, Laos, Malaysia, Nepal, Taiwan, Thailand, Philippines, and Vietnam.

DRAGON-Southeast Asia instrument deployments will occur in and around the island of Penang, Malaysia (Figure 2) and within Singapore (Figure 3) with approximately five regionally distributed instruments in each location.
