Aerosol Forecasting



Global forecasts of aerosols

MACC-II provides daily 5-day forecasts of global aerosol concentrations. Aerosol consists of small particles that are originate from deserts (red), sea salt (blue), wildfires and biomass burning (green), and anthropogenically emitted sulphates (white). Atmospheric transport carries them around the world, while at the same time gravity and rainfall slowly return the particles to the Earth surface.

Animation of desert dust episode over southern Europe

Europe, especially the southern part, is often affected by plumes of desert dust originating from the Sahara. MACC-II's daily forecasts capture these events and can provide some advance warning. This is important because dust can affect visibility and air quality. Dust also affects the generation of solar energy by diminishing the amount of direct solar radiation reaching the Earth's surface.

Air Pollution



Regional air quality forecasts

Daily 4-day forecasts are provided using 7 different air quality models. The forecast differences between the models are an indicator of the uncertainty. The example shows the forecast of nitrogen dioxide (NO2), which is an important indicator of poor air quality, from one of the models.

Climate Monitoring



Monitoring of methane fluxes

Atmospheric methane concentrations are monitored by MACC using its state-of-the-art atmospheric transport model together with observations from the European SCIAMACHY satellite instrument. These atmospheric analyses are then used in an inverse model to estimate the surface fluxes.

Carbon Dioxide


Carbon weather in September 2013

The distribution of CO2 in the atmopshere is not homogeneous but determined by fluxes at the surface in combination with the atmospheric transport. Photosynthesis, respiration, ocean exchange, biomass burning, and anthropogenic emissions all play a role. In combination with normal weather changes, such as cold and warm fronts, tropical cyclones, and trade winds, this results in beautiful dynamics, sometimes labeled 'carbon weather'.


Ozone Layer


2010 ozone hole

The destruction of ozone in the ozone layer over Antarctica this year is about 40 to 60% less compared to the previous five years, according to MACC analyses based on observations from the SCIAMACHY instrument on board of the European ENVISAT satellite. Less ozone destruction is consistent with the expectation that the ozone layer will recover during the coming decades due to reduction in the stratospheric amount of chlorine. However, such a large change cannot be attributed to the slow decrease of stratospheric chlorine of 0.5-1% per year. This year’s reduced ozone destruction turns out to be caused by unusual meteorological conditions. The MACC monitoring system enables the assessment of the interaction between meteorology and chemistry, allowing better interpretation of the changes in the ozone hole from year to year.
