New papers in Aerosol and Air Quality Research special issue

Validation of the ASHE algorithm, from Lee et al (2016)

This figure from Lee et al. (2016) shows (top) time series of ASHE and MPLNET aerosol top height (ATH), (middle) VIIRS and AERONET AOD, and (bottom) ASHE and AERONET SSA from the complete algorithm (left) and simplified algorithm (right). Only best QA data are shown. The MPLNET and AERONET data are presented only if there are ASHE retrieved ATH data, while the gray dots represent the full MPLNET/AERONET data records. The black vertical line separates 2013 and 2014.


A special issue of the journal Aerosol and Air Quality Research (AAQR) focusing on recent field deployments as part of the 7 South-East Asian Studies (7-SEAS) campaign has just been published. This field campaign was conceived to improve our understanding of the coupled aerosol-cloud-precipitation system in this region, with a particular emphasis on biomass burning (smoke) aerosols and related trace gases from the springtime burning season.


The issue contains two papers concerning the Deep Blue aerosol project. Lee et al. (2016) provided further case studies and evaluation of the Aerosol Single-scattering albedo and Height (ASHE) estimation algorithm. The study evaluates the height of smoke aerosols retrieved from a combined use of Visible Infrared Imaging Radiometer Suite (VIIRS), Ozone Mapping and Profiler Suite (OMPS), and Cloud-Aerosol Lidar with Orthogonal Polarization (CALIOP) observations. The retrieved heights are compared against spaceborne and ground-based lidar measurements, and a quality assurance (QA) procedure is developed for the data set.


Sayer et al. (2016) made use of the spring 2015 deployment of a suite of instrumentation at Doi Ang Khang in northwestern Thailand for the characterization of air masses containing smoke aerosols from burning predominantly in Myanmar. MODIS Collection 6 Deep Blue aerosol optical depth data were validated at this location. Deep Blue data were also used in combination with other remote sensing and in situ data for analysis of mass, chemical, and optical properties related to biomass burning emissions.
