Look at all the Aerosols Pushed into the Atmosphere, from Fires, Volcanoes and Pollution. Even Sea Salt Thrown into the Air from Hurricanes

Stand outside and take deep breath. Do you know what you’re breathing? For most people, the answer is simple – air. And air, which is essential to life as we know it, is composed of roughly twenty-percent oxygen gas (O²) and seventy-eight percent nitrogen gas (N²). However, within the remaining one-percent and change are several other trace gases, as well as few other ingredients that are not always healthy.

Interesting. The red is Black Carbon.

In Oz there is a hotspot in NT and a small one in north coast NSW.

Tennant creek?

Fascinating. I used to study the sea salt pushed into the air by strong winds, the roaring forties, furious fifties, as well as hurricanes. I would have killed for data this good back then.

not Tennant Creek, more like around Katherine.

Black carbon is that soot from fires. So bushfires in oz, volcanic in the Indonesian area and cooking fires in South Africa?

you’re way off with tennant creek.. more like Timber Creek

TC is a bit further south.

as you were :)

OK, bushfire then. I couldn’t imagine that there was any industry in or around Katherine that was generating that much soot.

be dry season bushfire i would imagine. Top End is full of them at that time.

The Modern-Era Retrospective analysis for Research and Applications, Version 2 (MERRA-2) provides data beginning in 1980. It was introduced to replace the original MERRA dataset because of the advances made in the assimilation system that enable assimilation of modern hyperspectral radiance and microwave observations, along with GPS-Radio Occultation datasets. It also uses NASA’s ozone profile observations that began in late 2004. Additional advances in both the GEOS model and the GSI assimilation system are included in MERRA-2. Spatial resolution is about 50 km in the latitudinal direction.

Along with the enhancements in the meteorological assimilation, MERRA-2 takes some significant steps towards GMAO’s target of an Earth System reanalysis. MERRA-2 is the first long-term global reanalysis to assimilate space-based observations of aerosols and represent their interactions with other physical processes in the climate system. MERRA-2 includes a representation of ice sheets over Greenland and Antarctica.

I don’t know how to interpret the following graph. Why are some altitudes cooling while other altitudes are warming?

Aerosol concentrations.

mollwollfumble said:

Aerosol concentrations.

The increase in carbonaceous aerosols with time is worrying, particularly that in Asia. But what’s the main cause?

It could be

• Bushfires.
• Agricultural burn-off.
• Increasing industry with inadequate pollution controls.
• Increasing motor vehicles with inadequate pollution controls.

The largest aerosols would be dust followed by sea salt. Sea salt is big at high latitudes where the mean wind speed is strongest.

A must read for anyone with an interest in world climate and climate change.

Lots of movies of many climatic parameters month by month movies and look at any month.

Look at the one for sea surface temperature to see El Nino in action. And if you want you can do a frame by frame comparison of El Nino and rainfall in Australia.

The most startling and strongest trend that I can see is visible in Russia in the map of Net Primary Productivity. Take a look.

Co2 is a fertiliser for plants, but they still need water to use it and the climate needs to be within a compatible temperature range. We are currently at the beginning of major climate change, but things will change further with weather extremes. Research has shown faster plant growth due to co2 simulation causes disruption to forest ecosystems by encouraging rapid growth species, at the expense of naturally slower growing ones. This will lead to lack of diversity – not good!
