Land Degradation &Development, EarlyView.ABSTRACT Soil erosion remains a major global concern affecting agricultural productivity and land sustainability. This study investigates the magnitude and variability of soil erosion in a long‐term experiment (LTE) established in 1963 in Colonia, Uruguay, aiming to compare the performance of the 137Cs tracer technique and the RUSLE model across ...

Rainfall, runoff and temperature fluctuations in the Amazon basin and oscillation of global climate over the last century [PDF]
, 1994 Over the past century, the world's climate has been changing. The rainfall over the continents, the global stream water discharge, the global air temperature and the CO2 content in the atmosphere have together been increasing.

People and Nature, EarlyView.Abstract Afromontane ecosystems, characterised by mosaics of fire‐adapted grassy ecosystems and fire‐sensitive forests, are biodiversity hotspots facing escalating pressures from non‐native species, climate and land‐use change. Madagascar's Central Highlands is one such hotspot, hosting woodlands dominated by endemic Uapaca bojeri (tapia) which are ...

On the impact of transport model errors for the estimation of CO2 surface fluxes from GOSAT observations [PDF]
, 2010 A series of observing system simulation experiments is presented in which column averaged dry air mole fractions of CO2 (XCO2) from the Greenhouse gases Observing SATellite (GOSAT) are made consistent or not with the transport model embedded in a flux ...

Permafrost and Periglacial Processes, EarlyView.ABSTRACT Under continued climate warming, understanding present‐day permafrost distribution and the controls on ground thaw are critical for predicting permafrost thaw trajectories and associated implications. This study presents a high‐resolution investigation of permafrost extent and active layer thickness (ALT) across a coniferous forested hillslope

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.
