The MISR Research Product Algorithm – producing global, self-consistent, pixel-level aerosol retrievals for the Multi-angle Imaging SpectroRadiometer

Abstract. The MISR Research Aerosol retrieval algorithm (RA) was developed in parallel with the MISR standard operational algorithm (SA), to explore innovative retrieval ideas for possible implementation in the SA, and to provide higher-spatial-resolution results with enhanced se...

TPHH: a long-term (1901–2023) high-resolution (1∕30°) near-surface humidity dataset for the Tibetan Plateau generated via spatial downscaling based on hybrid-structure deep learning

The Tibetan Plateau acts as the “Asian Water Tower” and faces regional amplified warming compared to the global climate change baseline. Given the Tibetan Plateau's pronounced alpine terrain, i.e., significant elevation gradients within short horizontal distances, studies on clim...

Significant Reduction in Ethane Emissions in the Denver‐Julesburg Basin From 2015 to 2021 From Oil and Natural Gas Operations

Abstract Top‐down studies of methane (CH 4 ) emissions often use the average ethane‐to‐methane (C 2 /C 1 ) ratio of wellhead gas in a basin to attribute emissions to thermogenic or biogenic sources. Biogenic CH 4 sources (ruminants, wetlands, landfills, and other methanogenic sou...

Projected burden of humid-heat on paediatric asthma in Shanghai under climate change scenarios: A time-series study

Climate change is intensifying the frequency and severity of extreme heat events. While the impact of temperature on respiratory health is well-documented, the synergistic effects of combined heat and humidity are less clear, especially for children, a population with heightened...

Characterization of the ecological impacts of prescribed fire in South America: a review

Prescribed fire has been shown to offer substantial benefits to both human populations and ecosystems, but it can also cause environmental harm, such as reduced air quality and negative impacts on sensitive species. To support the appropriate use of prescribed fire, stakeholders...

Exploring the hydrogen abstraction pathway in HOM formation from α -pinene photooxidation systems under varying NO conditions

Abstract. Highly oxygenated organic molecules (HOM) are formed via autoxidation during ⚫OH-initiated oxidation of α-pinene. We investigated the relative contributions of OH-addition and hydrogen (H)-abstraction to HOM formation from α-pinene photooxidation under varying nitrogen...

Method for Calculating a Generic Oil

Accidental oil spills are an all-too-common occurrence. In order to properly plan for and respond to oil spills, responders and planners need to understand how the oil will behave in the environment: how it will weather and how it will affect ecosystems and biota. To address this...

Layer‐Dependent Diurnal Moist Static Energy Biases in the Unified Forecast System During the MJO Preconditioning Stage: A DYNAMO Case Study

Abstract Accurate simulation of the Madden‐Julian Oscillation (MJO) requires realistic diurnal evolution and vertical distribution of moist static energy (MSE). While prior studies documented MSE bias in simulations, vertically dependent physical processes responsible for these b...

The recent enhancement of the surface melt over the Antarctic Peninsula dictated by thermodynamics

Intense surface melt and subsequent meltwater ponding are the key triggers for the disintegration of ice shelves in the Antarctic Peninsula (AP). Although a long-term decline in AP surface melt has been evident since the early 1990s, episodes of intense surface melt events have f...
