Albedo, Land Cover, and Daytime Surface Temperature Variation Across an Urbanized Landscape

, 2017
Land surface albedo is a key parameter controlling the local energy budget, and altering the albedo of built surfaces has been proposed as a tool to mitigate high near‐surface temperatures in the urban heat island.

UCanWBGT: urban street canyon heat stress calculation for weather and climate models

Quarterly Journal of the Royal Meteorological Society, EarlyView.
This work introduces UCanWBGT, a new model to calculate wet‐bulb globe temperature in an urban environment, suitable for use with weather and climate model data. We present the model, then verify its performance against observations made in the streets of Paris during heatwave conditions.

A pilot variational coupled reanalysis based on the CESAM climate model

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Variational data assimilation of in‐situ and satellite ocean data and reanalysis atmospheric data into an intermediate complexity Earth system model is possible by adjusting the surface fluxes and internal model parameters. This pilot application requires nearly complete information on the atmospheric state for synchronization.

Evaluation of surface albedo products from ERA5, JRA-55, MERRA-2, and CERES-EBAF on the Tibetan Plateau: insights from in-situ observations and MODIS data

International Journal of Digital Earth
Land surface albedo is essential for comprehending energy budget and climate effects. However, significant discrepancies exist in various albedo datasets, primarily due to variations in the surface data and simulation models employed. This study assessed

Internal physiological drivers of leaf development in trees: Understanding the relationship between non‐structural carbohydrates and leaf phenology

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Plant phenology is crucial for understanding plant growth and climate feedback. It affects canopy structure, surface albedo, and carbon and water fluxes. While the influence of environmental factors on phenology is well‐documented, the role of plant intrinsic factors ...

Investigating the spread in surface albedo for snow‐covered forests in CMIP5 models

, 2015
This study investigates the role of leaf/plant area index (LAI/PAI) specification on the large spread of winter albedo simulated by climate models. To examine the sensitivity of winter albedo to LAI, we perform a sensitivity analysis using two methods ...

Climate Change, Air Quality, and Pollen Allergies—State of the Art and Recommendations for Research and Public Health

Allergy, EarlyView.
ABSTRACT Allergies are one of the major health challenges of our time, associated with a high individual burden of disease and high costs for the healthcare system. Given their prevalence, allergies are also highly relevant from a public health perspective. The development of allergic diseases is multifactorial. In addition to individual factors (e.g.,

Human-Induced Landcover Changes Drive a Diminution of Land Surface Albedo in the Loess Plateau (China)

Remote Sensing, 2015
A large decrease in the land surface albedo of the Loess Plateau was observed from 2000 to 2010, as measured using satellite imagery. In particular, ecological restoration program regions experienced a decrease in peak season land surface albedo ...
