Meteorological data collected during the post‐9/11 flight grounding in the United States suggested that the removal of contrails increased diurnal temperature range (DTR), but subsequent research has contested this result.

Influence assessment of physical and geographical conditions for flat terrain on flight visibility [PDF]
Introduction. A flight visibility model is presented that takes into account the nature of the underlying surface, the height of the flat terrain, and the dynamics of the aircraft flight due to changes in altitude and ground speed during aerial work ...

Foehn warming distributions in nonlinear and linear flow regimes: a focus on the Antarctic Peninsula [PDF]
The structure of lee-side warming during foehn events is investigated as a function of cross-barrier flow regime linearity. Two contrasting cases of westerly flow over the Antarctic Peninsula (AP) are considered – one highly nonlinear, the other ...

OpenAP.top: Open Flight Trajectory Optimization for Air Transport and Sustainability Research
Trajectory optimization has been an active area of research for air transport studies for several decades. But almost all flight optimizers proposed in the literature remain close-sourced, which presents a major disadvantage for the advancement of ...

A new method to correct the electrochemical concentration cell (ECC) ozonesonde time response and its implications for “background current” and pump efficiency [PDF]
The electrochemical concentration cell (ECC) ozonesonde has been the main instrument for in situ profiling of ozone worldwide; yet, some details of its operation, which contribute to the ozone uncertainty budget, are not well understood.

A review and framework for the evaluation of pixel-level uncertainty estimates in satellite aerosol remote sensing [PDF]
Recent years have seen the increasing inclusion of per-retrieval prognostic (predictive) uncertainty estimates within satellite aerosol optical depth (AOD) data sets, providing users with quantitative tools to assist in the optimal use of these data ...

Chemical transport model ozone simulations for spring 2001 over the western Pacific:comparisons with TRACE-P lidar, ozonesondes, and Total Ozone Mapping Spectrometer columns [PDF]
Two closely related chemical transport models (CTMs) employing the same high-resolution meteorological data (similar to180 km x similar to180 km x similar to600 m) from the European Centre for Medium-Range Weather Forecasts are used to simulate the ozone

Warming summers limit reindeer grazing, weakening herbivory pressure in the mountain tundra
Climate change is predicted to alter species interactions by exposing ecosystems to increasingly frequent and intense warm spells. In the mountain tundra, grazing by large herbivores, particularly reindeer, can limit shrub expansion and preserve Arctic plant diversity.

Beyond birds: rethinking bird‐centered pathogen models in light of insect migration
Migration redistributes biomass, nutrients, and pathogens across ecosystems. For decades, migratory birds have been treated as the default long‐distance pathogen vectors, shaping both conceptual frameworks and empirical models of disease ecology.
