Reviews and syntheses: Carbonyl sulfide as a multi-scale tracer for carbon and water cycles
- Biogeosciences
- DOI 10.5194/bg-15-3625-2018
- 18 June 2018
Measurements of the trace gas carbonyl sulfide (OCS) are helpful in quantifying photosynthesis at previously unknowable temporal and spatial scales. While CO2 is both consumed and produced within ecosystems, OCS is mostly produced in the oceans or from specific industries, and destroyed in plant leaves in proportion to CO2. This review summarizes the advancements we have made in the understanding of OCS exchange and applications to vital ecosystem water and carbon cycle questions.
Field-warmed soil carbon changes imply high 21st-century modeling uncertainty
- Biogeosciences
- DOI 10.5194/bg-15-3659-2018
- 18 June 2018
The temperature sensitivity of soil carbon loss is a critical parameter for projecting future CO2. Isolating soil temperature response in the field is challenging due to difficulties isolating root and microbial respiration. We use a database of direct-warming soil carbon changes to generate a new global temperature sensitivity. Incorporating this into Earth system models reduces projected soil carbon. But it also shows that variation due to this parameter is as high as all other causes.
Estimates of ozone return dates from Chemistry-Climate Model Initiative simulations
- Atmospheric Chemistry and Physics
- DOI 10.5194/acp-18-8409-2018
- 15 June 2018
We analyse simulations from the Chemistry-Climate Model Initiative (CCMI) to estimate the return dates of the stratospheric ozone layer from depletion by anthropogenic chlorine and bromine. The simulations from 20 models project that global column ozone will return to 1980 values in 2047 (uncertainty range 2042–2052). Return dates in other regions vary depending on factors related to climate change and importance of chlorine and bromine. Column ozone in the tropics may continue to decline.
On the social dynamics of moisture recycling
- Earth System Dynamics
- DOI 10.5194/esd-9-829-2018
- 14 June 2018
Moisture recycling is the atmospheric branch of the water cycle, including evaporation and precipitation. While the physical water cycle is well-understood, the social links among the recipients of precipitation back to the sources of evaporation are not. In this work, we develop a method to determine how these social connections unfold, using a mix of quantitative and qualitative methods, finding that there are distinct types of social connections with corresponding policy and management tools.
Imaggeo on Mondays: The breath of our Earth

This picture was taken in the Myvatn geothermal area in southeast Iceland. Seeing the geothermal steam vent in this area while the temperature was -22 degrees Celsius is the best experience in Myvatn. The difference between Iceland’s cold ambient temperature and the released heat from inside the Earth is a really stunning event to see. Iceland is situated in the middle of two tectonic plates (the Eurasian and North American plates) that, through their movement, have led to more than …
Image of the Week -- Orange is the new white

On 22 March 2018, large amounts of Saharan dust were blown off the Libyan coast to be further deposited in the Mediterranean, turning the usually white snow-capped Mountains of Turkey, Romania and even Caucasus into Martian landscapes. As many people were struck by this peculiar color of the snow, they started documenting this event on social media using the “#orangesnow hashtag”. Instagram and twitter are fun, but satellite remote sensing is more convenient to use to track the orange snow …
The average magnetic field and polar current system (AMPS) model
- Solar-Terrestrial Sciences
- posted 3 days ago
In this month’s post, Karl Magnus Laundal explains a newly developed empirical model for the full high latitude current system of the Earth’s ionosphere, AMPS (Average Magnetic field and Polar Current System). The model is available and documented in python code, published under the acronym pyAMPS. The community is invited to download and explore the electric currents and magentic field disturbances described by the model. The average magnetic field and polar current system (AMPS) model At about 10 times airline …
