In this study an algal bloom event in fall 2013 in the Strait of Hormuz was thoroughly investigated using satellite remote sensing and hydrodynamic modeling. The motivation of this study is to deduce ambient conditions prior to and during the bloom outbreak and understand its trigger. Bloom tracking was achieved by sequential MODIS imagery and numerical simulations. Satellite observations showed that the bloom was initiated in late October 2013 and dissipated in early June 2014. Trajectories of bloom patches were simulated using a Lagrangian transport model. Model-based predictions of bloom patches' trajectories were in good agreement with satellite observations with a probability of detection (POD) reaching 0.85. Analysis of ancillary data, including sea surface temperature, ocean circulation, and wind, indicated that the bloom was likely caused by upwelling conditions in the Strait of Hormuz. Combined with numerical models, satellite observations provide an essential tool for investigating bloom conditions.

Treatment of seeds with cold atmospheric pressure plasma (CAPP) is in its proof-of-concept phase with regard to its effect on germination and plant growth. To increase the germination of hardseeded red clover (Trifolium pratense L.), seeds are usually scarified, which is time-consuming and labour-intensive.

Vegetation phenology, i.e., seasonal biological events such as leaf-out and leaf-fall, regulates local climate through biophysical processes like evapotranspiration (ET) and albedo.

Absorption spectra of neopentyl alcohol and pinacolyl alcohol are recorded in the gas phase at room temperature and equilibrium conditions. A combination of conventional Fourier transform spectroscopy and cavity ringdown spectroscopy is used to cover the spectral OH-stretching regions, Δv=1-5. The conformer distributions of the alcohols are determined from the recorded spectra combined with transition intensities calculated with a reduced dimensional local mode model.

Drought stress has profound impacts on ecosystems and societies, particularly in the context of climate change. Traditional drought indicators, which often rely on integrated water budget anomalies at various time scales, provide valuable insights but often fail to deliver clear, real-time assessments of vegetation stress. This study introduces the Cooling Efficiency Factor Index (CEFI), a novel metric purely derived from geostationary satellite observations, to detect vegetation drought stress by analyzing daytime surface warming anomalies.

Background: Residential greenness is an important environmental factor potentially influencing the development of allergic diseases in adolescents; however, its impact remains understudied in South Korea. This study aimed to examine the association between residential greenness and allergic disease prevalence using nationally representative data.
Method: We analyzed data from 1,130,598 adolescents (7-12th grade) participating in the Korean Youth Risk Behavior Web-based Survey (2007-2024).
