Volcanic aerosols from the 1991 Mount Pinatubo eruption greatly increased diffuse radiation worldwide for the following 2 years. We estimated that this increase in diffuse radiation alone enhanced noontime photosynthesis of a deciduous forest by 23% in 1992 and 8% in 1993 under cloudless conditions. This finding indicates that the aerosol-induced increase in diffuse radiation by the volcano enhanced the terrestrial carbon sink and contributed to the temporary decline in the growth rate of… 

Pinatubo, Diffuse Light, and the Carbon Cycle

Similar to clouds, volcanic eruptions increase the proportion of diffuse light reaching Earth9s surface. As Farquhar and Roderick show in their Perspective, this change in the geometry (rather than

Climate and carbon cycle response to the 1815 Tambora volcanic eruption

The sulphur released by the 1815 Tambora volcanic eruption resulted in a net cooling after the eruption. The cold climate was responsible for crop failures, leading to serious famine and high food

CO2 seasonality indicates origins of post‐Pinatubo sink

An enhanced carbon sink of ∼2PgC/yr was observed following the Mount Pinatubo eruption. In this study we used a biogeochemical model (CASA) linked to an atmospheric tracer model (MATCH) with

Enhanced Photosynthesis and Transpiration in an Old Growth Forest Due To Wildfire Smoke

We document the response of a 2 day wildfire smoke event on a moist temperate coniferous old‐growth forest in the western U.S. Wildfire smoke increased air temperature and suppressed relative

Ecological impacts of degassing From Masaya Volcano, Nicaragua

Persistent degassing is an unusual type of volcanic activity with considerable environmental impacts, although its effects on downwind ecosystems are poorly researched. Up to 1000 tonnes of SO2 per

Fires increase Amazon forest productivity through increases in diffuse radiation

Atmospheric aerosol scatters solar radiation increasing the fraction of diffuse radiation and the efficiency of photosynthesis. We quantify the impacts of biomass burning aerosol (BBA) on diffuse


Understanding the processes that change the amount of carbon stored in the ocean and in the land biota, with their implications for future climate and ecology, is a fundamental goal of earth-system

Impacts of large-scale climatic disturbances on the terrestrial carbon cycle

It is concluded that during the last 25 years the two largest disturbances of the global carbon cycle were strongly controlled by soil processes rather then the response of vegetation to these large-scale climatic events.

Understanding Volcanoes May Be the Key to Controlling Global Warming

Volcanoes are the primary source of gases in the earth’s atmosphere and have been the primary cause of short-period climate change throughout geologic history. The large eruption of Pinatubo volcano



Climatic Control of the High-Latitude Vegetation Greening Trend and Pinatubo Effect

A biogeochemical model of vegetation using observed climate data predicts the high northern latitude greening trend over the past two decades observed by satellites and a marked setback in this trend

Atmospheric effects of the Mt Pinatubo eruption

The eruption of Mt Pinatubo in June 1991 caused the largest perturbation this century to the participate content of the stratosphere. The radiative influence of the injected particles put an end to

The Climatic Aftermath

The eruption of Mount Pinatubo on 15 June 1991 produced the largest stratospheric volcanic aerosol cloud of the 20th century. About 20 megatons of SO2 was injected into the stratosphere, affecting

Radiative Climate Forcing by the Mount Pinatubo Eruption

Radiative flux anomalies derived from the National Aeronautics and Space Administration (NASA) spaceborne Earth Radiation Budget Experiment were used to determine the volcanic radiative forcing that

The poleward dispersal of Mount Pinatubo volcanic aerosol

Using the SAGE II 1-μm stratospheric aerosol extinction ratio observations, the dispersal of Mount Pinatubo aerosol within two transport regimes during the first 10 months after the eruption is

Carbon dioxide exchange between an undisturbed old-growth temperate forest and the atmosphere

Ecosystem COZ uptake was enhanced by diffuse PPFD, a result of potentially global significance given recent increases in Northern Hemisphere haze, and a new result has implications for the development of models for diurnal ecosystem CO, exchange.

Net Exchange of CO2 in a Mid-Latitude Forest

The eddy correlation method was used to measure the net ecosystem exchange of carbon dioxide continuously from April 1990 to December 1991 in a deciduous forest in central Massachusetts, and carbon uptake rates were notably larger than those assumed for temperate forests in global carbon studies.

Global surface air temperature in 1995: Return to pre‐Pinatubo level

Global surface air temperature has increased about 0.5°C from the minimum of mid-1992, a year after the Mt. Pinatubo eruption. Both a land-based surface air temperature record and a land-marine

Radiative forcing from the 1991 Mount Pinatubo volcanic eruption

Volcanic sulfate aerosols in the stratosphere produce significant long-term solar and infrared radiative perturbations in the Earth's atmosphere and at the surface, which cause a response of the
