Impact of extreme rainstorm on the spatial distribution of population exposure in Haihe River basin in ChinaNARA Subscribed
Based on daily rainfall data from 252 national meteorological stations in the Haihe River Basin of China during 1961–2023, rainstorm events were divided, and four characteristic variables representing the hazard index of rainstorms were statistically analyzed, including total number of rainstorm days ( I day ), cumulative rainfall ( I pre ), average daily rainfall ( I 24pre ), and maximum duration days ( I dur ). Combined with...
Closing Knowledge Gaps on Global Budget of Nitrogen Oxides ( NO x ) by Quantifying Indirect Emissions From Anthropogenic NitrogenNARA Subscribed
Human activities emit nitrogen oxides (NO x ≡ NO + NO 2 ; with source emissions approximated as nitric oxide (NO)), potent air pollutants and short‐lived climate forcers, through direct and indirect pathways. Unlike direct releases, however, indirect NO x emissions remain poorly understood and inadequately quantified. Here, by synthesizing available observations across global terrestrial ecosystems, we show that soil moisture...

Metabarcoding Chironomid Pupal Exuviae Enables Scalable Biomonitoring With High Comparability to MorphotaxonomyNARA Subscribed
Conventional morphotaxonomy‐based biomonitoring requires modernization to enable timely assessments in the face of an accelerating freshwater biodiversity crisis. The Chironomid Pupal Exuviae Technique (CPET) is an established biomonitoring approach with considerable potential for integration with molecular methods, as the shed pupal skins of emerging adults provide a source of DNA. We tested the performance of DNA metabarcodi...
The Fukushima Daiichi Nuclear Power Plant accident released radionuclides directly into the ocean as a result of the Great East Japan Earthquake on March 11, 2011. This material has been transported across the Pacific Ocean and detected in the northeastern Pacific. We began a surface ocean 129 I monitoring program a few months after this disaster in June 2011, with samples from Scripps Pier, La Jolla, California, USA, with the...
