The land and sea routes to 2030: a call for greater attention on all small islands in global environmental policy. npj biodivers 2, 18 (2023).

Abstract Islands have unique vulnerabilities to biodiversity loss and climate change. Current Nationally Determined Contributions under the Paris Agreement are insufficient to avoid the irreversible loss of critical island ecosystems. Existing research, policies, and finance also do not sufficiently address small islands’ social-environmental...

Total Organic Carbon and the Contribution from Speciated Organics in Cloud Water: Airborne Data Analysis from the CAMP2Ex Field Campaign. Atmospheric Chemistry and Physics, 21(18), 14109–14129.

Abstract This work focuses on total organic carbon (TOC) and contributing species in cloud water over Southeast Asia using a rare airborne dataset collected during NASA’s Cloud, Aerosol and Monsoon Processes Philippines Experiment (CAMP2Ex), in which a wide variety of maritime clouds were...

Measurement Report: Firework Impacts on Air Quality in Metro Manila, Philippines, During the 2019 New Year Revelry. Atmospheric Chemistry and Physics, 21(8), 6155–6173.

Abstract Fireworks degrade air quality, reduce visibility, alter atmospheric chemistry, and cause short-term adverse health effects. However, there have not been any comprehensive physicochemical and optical measurements of fireworks and their associated impacts in a Southeast Asia megacity, where fireworks are a regular...

Measurement Report: Long-Range Transport Patterns into the Tropical Northwest Pacific During the CAMP2Ex Aircraft Campaign: Chemical Composition, Size Distributions, and the Impact of Convection. Atmospheric Chemistry and Physics, 21(5), 3777–3802.

Abstract The tropical Northwest Pacific (TNWP) is a receptor for pollution sources throughout Asia and is highly susceptible to climate change, making it imperative to understand long-range transport in this complex aerosol-meteorological environment. Measurements from the NASA Cloud, Aerosol, and Monsoon Processes Philippines...

Particulate Oxalate-To-Sulfate Ratio as an Aqueous Processing Marker: Similarity Across Field Campaigns and Limitations. Geophysical Research Letters, 48(23), e2021GL096520.

Abstract Leveraging aerosol data from multiple airborne and surface-based field campaigns encompassing diverse environmental conditions, we calculate statistics of the oxalate-sulfate mass ratio (median: 0.0217; 95% confidence interval: 0.0154–0.0296; R = 0.76; N = 2,948). Ground-based measurements of the oxalate-sulfate ratio fall within...

Contrasting the Size-Resolved Nature of Particulate Arsenic, Cadmium, and Lead Among Diverse Regions. Atmospheric Pollution Research, 12(3), 352–361.

Abstract This study examines the mass size distributions and crustal enrichment factors (EFs) of arsenic (As), cadmium (Cd), and lead (Pb) for diverse regions: coastal marine (Marina, California), arid mining facility (Hayden, Arizona), arid urban (Tucson, Arizona), free troposphere (Mt. Lemmon, Arizona), and...

The Multihazard Risk Atlas of Maldives: Geography—Volume I, Climate and Geophysical Hazards—Volume II, Economy and Demographics—Volume III, Biodiversity—Volume IV, and Summary—Volume V.

This atlas provides spatial information about Maldives and thematic maps necessary for assessing future development investments in terms of climate risks and geophysical hazards. It is also intended to support the formulation of cobeneficial options for climate change adaptation and disaster risk reduction...

Projected Evolution of Drought Characteristics in Vietnam Based on CORDEX-SEA downscaled CMIP5 data. International Journal of Climatology.

Abstract In this study, the projected drought characteristics over Vietnam for the future periods of the middle (2046–2065) and end of the 21st century (2080–2099) were investigated under the Representative Concentration Pathway (RCP) scenarios RCP4.5 and RCP8.5. The drought characteristics (duration, severity, intensity,...

Potential Influence of Sea Surface Temperature Representation in Climate Model Simulations over CORDEX-SEA Domain. International Journal of Climatology.

Abstract Regional climate simulations from the Southeast Asia Regional Climate Downscaling/Coordinated Regional Climate Downscaling Experiment – Southeast Asia (SEA) indicated model biases in temperature and rainfall over SEA. Given the influence of sea surface temperature (SST) variability on SEA climate, this study examines...
