Welcome

Welcome to our website for ATTO, the Amazon Tall Tower Observatory – an Amazon research project.

This research site is located in the middle of the Amazon rainforest in northern Brazil, about 150 km north of Manaus. It is run together by scientists from Germany and Brazil. Its aim is to continuously record meteorological, chemical and biological data, such as the concentration of greenhouses gases. With the help of these data, we hope to gain insights into how the Amazon interacts with the overlying atmosphere and the soil below. Because this region is of such importance to the global climate, it is vital to get a better understanding of these complex processes. Only then will we be able to make more accurate climate predictions.

Have a look around on our website to learn more about the research performed at ATTO and in labs and offices around the world. Please note that the website is still under constructions and more content will be added. So be sure to check back soon! You can also follow us on Social Media to get an insight into the daily lives of the ATTO scientists and stay up-to-date on all the latest news and events!

New Publication: Comparing air pollution in Manaus and at ATTO by identifying aerosols

You have probably heard a lot about air pollution recently, comparing air pollution in Manaus and in the Amazon rainforest by analyzing what aerosols are present. Edited after Wu et al. (2018)be it because of the massive wildfires in California, smog in India or the diesel emission scandal in Germany. So let’s look into air pollution in the Amazon. Most air pollutants are actually aerosols. Identifying these aerosols and their chemical composition can help us understand where they come from and to what extent certain regions are affected by air pollutions. That is exactly what Li Wu and co-authors did in their new study in the Amazon rainforest.

They collected and analyzed aerosols in two locations: the city of Manaus, a large urban area in Brazil, and the ATTO site in the heart of the forest. The samples were collected during the wet season when ATTO is mainly influenced by air masses from the Atlantic and is located upwind from Manaus. And indeed they found that at ATTO the aerosols are mostly of organic origin, emitted by the forest itself. Additionally, they could identify mineral dust and sea-salt particles. In contrast, they frequently found soot, fly ash and particles containing heavy metals in the samples in Manaus. These are most likely produced by human activities. The good news is that such anthropogenic particles are still largely absent from the atmosphere over the rainforest, showing us that pristine wilderness regions do still exist. That is, at least during the wet season when the winds blow in the “right” direction.

The scientists published the study in Atmospheric Chemistry and Physics (ACP) and is available Open Access here.

AGU Fall Meeting 2018

The AGU Fall Meeting 2018 is approaching fast. Before you all finish up your schedules, we want to draw your attention to the presentations from our ATTO team!

Tuesday, 11 December

Wednesday, 12 December

Friday, 14 December

This year’s AGU Fall Meeting takes place from December 10 – 14 at the Convention Center in Washington D.C. Hope to see you all there! If you can’t make it to AGU, be sure to follow us on Social Media to get a glimpse into the conference and ATTO’s presence there.

 

EGU 2019

Are you heading to the EGU 2019? If the answer is ‘yes’ we might have just the right session for you!

Next year, some members of the ATTO team are convening a session at next years EGU titled “Intact Amazon forest – a natural laboratory of global significance” (BG2.4/AS3.35/HS11.64/SSS10.12). This session aims at bringing together scientists who investigate the functioning of the Amazon and comparable intact forest landscapes across spatial and temporal scales by means of observational, modeling, and theoretical studies. Particularly welcome are also presentations of new, interdisciplinary approaches and techniques. We specifically invite contributions from a great variety of projects investigating the Amazon and its significance for the Earth System and hope many of you will submit abstracts to the session!

EGU 2019 is taking place from  April 7 to 12 in Vienna, Austria, as usual. Travel Grants are offered, for example for Early Career Scientists.

Hope to see you there to gain new insights, inspire new approaches and collaborations and share our passion for performing research in this unique ecosystem with global importance.

 

ATTO Newsletter #1

The first edition of our new ATTO Newsletter was just released.

Four times a year, the newsletter will keep you up-to-date on everything that happened in the past several months, such as new scientific articles that have been published, infrastructural updates and meeting that happened. In addition, we provide info on upcoming conferences with abstract submission deadlines or an overview of presentations of ATTO data. And it is also a platform to share some of the stunning photos from the Amazon around the ATTO site, especially to those who don’t follow our Instagram.

To receive the newsletter, please subscribe to our mailing list, subscribe to the RSS feed or follow us on social media. All newsletters will be archived here on the website as well.

New Publication: Air turbulence characteristics in and above the Amazon rainforest canopy

One of our major goals at ATTO is understanding how the Amazon rainforest interacts with the atmosphere above. This includes studying how the characteristics of the air change within and above the tree canopy in terms of atmospheric turbulence. The strength of the wind and the thickness of the canopy determine, among other things, how well the air can mix and to what degree gases from the atmosphere may reach the forest floor and vice versa.

In a new study, the scientists were looking into these processes at two Amazon sites, including ATTO. They found that the lowermost air-layer from the forest floor to about half the tree height is largely decoupled from the air in the upper part of the canopy and above. That is an important finding, as this process may limit the extent to which plant-emitted gases are transported out of the forest canopy into the atmosphere above.
Raoni Aquino and co-authors now published their findings in a new study called “Air turbulence characteristics at multiple sites in and above the Amazon rainforest canopy” in the journal Agricultural and Forest Meteorology, Volume 260-261.
