The Role of Awakening Cortisol and Psychological Distress in Diurnal Variations in Affect: A Day Reconstruction Study [PDF]

open access: yes
People often feel unhappy in the morning but better later in the day, and this pattern may be amplified in the distressed. Past work suggests that one function of cortisol is to energize people in the mornings. In a study of 174 students we tested to see

The impact of the diurnal cycle on the propagation of Madden‐Julian Oscillation convection across the Maritime Continent

open access: yesJournal of Advances in Modeling Earth Systems, 2016
Influences of the diurnal cycle on the propagation of the Madden‐Julian Oscillation (MJO) convection across the Maritime Continent (MC) are examined using cloud‐permitting regional model simulations and observations.

A mosaic of microclimates: biodiversity outcomes and wildlife habitat potential in large‐scale solar facilities

open access: yesBiological Reviews, EarlyView.
ABSTRACT The rapid global expansion of photovoltaic (PV) solar facilities, now comprising nearly 80% of the recent and projected growth of renewable electricity, represents one of the most significant land‐use changes of the 21st century. While PV facilities are critical for decarbonising energy systems, their large spatial footprint and infrastructure

Orchard netting impacts on biodiversity leading to cascading effects at the ecosystem level

open access: yesBiological Reviews, EarlyView.
ABSTRACT Agriculture must ensure food production without further compromising the ecosystem functions upon which it depends. Agricultural practices should therefore avoid harming farmland biodiversity, especially of taxa that supply the key ecosystem services (e.g.

Dust Emissions on Mars From Phoenix Lidar Measurements in Relation to Local Meteorological Conditions

open access: yesGeophysical Research Letters
The diurnal cycle of dust aerosols on Mars is studied by analyzing lidar observations at the Phoenix landing site under cloud‐ and fog‐free conditions and in the absence of elevated, long‐range transported dust layers. There is a pronounced diurnal cycle

Diurnal cloud cycle biases in climate models

open access: yesNature Communications, 2017
The timing of clouds is critical to the Earth’s energy balance. Here the authors show that in current climate models, clouds over the land tend to peak too early in the morning, reflecting less solar radiation than observed.

Key Challenges for Commercializing Perovskite–Silicon Tandem Solar Cells

open access: yesCarbon Energy, EarlyView.
This review discusses the scientific and technological challenges in advancing perovskite–silicon tandem solar cells (PSTSCs) from lab‐scale to commercial viability, focusing on long‐term stability, scalability, and economic feasibility. Key issues include intrinsic and extrinsic degradation factors, installation conditions, environmental impacts, and ...

Radiation and the Diurnal Cycle [PDF]

open access: yes, 1996
This undergraduate meteorology tutorial is the first in a series explaining how and why the temperature rises and falls at the surface of the Earth. Various hypotheses for the diurnal cycle are explored.
