Abstract. The estimated global CO2 emission rates and the measured atmospheric CO2 concentrations show that only a certain share of the emitted CO2 accumulates in the atmosphere. For given atmospheric emissions of CO2, the effective lifetime determines its accumulation in the atmosphere and, consequently, its impact on the future global warming. We found that on average the inferred effective lifetime of CO2 decreases as its atmospheric concentration increases, reducing the rate of its accumulation in the atmosphere. We derived a power function that fits the varying lifetimes. Based on this fi

Abstract. The dominant removal mechanism of soluble aerosol is wet deposition. The atmospheric lifetime of aerosol, relevant for aerosol radiative forcing, is therefore coupled to the atmospheric cycling time of water vapor. This study investigates the coupling between water vapor and aerosol lifetimes in a well-mixed atmosphere. Based on a steady-state study by Pruppacher and Jaenicke (1995) we describe the coupling in terms of the processing efficiency of air by clouds and the efficiencies of water vapor condensation, of aerosol activation, and of the transfer from cloud water to precipitati

Abstract. Chlorofluorocarbons (CFCs) play a key role in stratospheric ozone loss and are strong infrared absorbers that contribute to global warming. The stratospheric lifetimes of CFCs are a measure of their stratospheric loss rates that are needed to determine global warming and ozone depletion potentials. We applied the tracer–tracer correlation approach to zonal mean climatologies from satellite measurements and model data to assess the lifetimes of CFCl3 (CFC-11) and CF2Cl2 (CFC-12). We present estimates of the CFC-11/CFC-12 lifetime ratio and the absolute lifetime of CFC-12, based on a r

Abstract The time water vapor spends in the atmosphere from evaporation to precipitation, termed here the water vapor lifetime, is of fundamental relevance for characterizing the water cycle, for the turnover of mass and energy, causes of precipitation extremes, and the recycling of precipitation over land. While the global average lifetime of water vapor is commonly considered as about 8–10 days, recent work indicates that the distribution of water vapor lifetimes is highly skewed, and that a large part of the water vapor could have average lifetimes of about 4–5 days.

The atmospheric lifetime of aerosol is thus closely coupled to the atmospheric cycling time of water vapor.

Abstract. Long lived halogen-containing compounds are important atmospheric constituents since they can act both as a source of chlorine radicals, which go on to catalyse ozone loss, and as powerful greenhouse gases. The long term impact of these species on the ozone layer is dependent on their stratospheric lifetimes. Using observations from the Atmospheric Chemistry Experiment Fourier Transform Spectrometer (ACE-FTS) we present calculations of the stratospheric lifetimes of CFC-12, CCl4, CH4, CH3Cl and N2O.

The instantaneous mortality rate (M) is an important parameter in elasmobranch management and conservation, but is difficult to estimate directly. Thus, indirect estimates based on relatively easily obtained life history parameters are commonly used. Many indirect methods incorporate one or more parameters from the von Bertalanffy growth model (VBGM), which is often criticized for its inability to describe changes in growth associated with maturity. The Lester growth model (LGM) is a biphasic alternative to the VBGM that incorporates trade-offs between reproduction, growth, and survival, and m

The atmospheric circulation in the mid-latitudes of both hemispheres is usually dominated by westerly winds and by planetary-scale and shorter-scale synoptic waves, moving mostly from west to east. A remarkable and frequent exception to this “usual” behavior is atmospheric blocking. Blocking occurs when the usual zonal flow is hindered by the establishment of a large-amplitude, quasi-stationary, high-pressure meridional circulation structure which “blocks” the flow of the westerlies and the progression of the atmospheric waves and disturbances embedded in them.

Abstract Nevertheless, it is still one of the more important minor constituents of the atmosphere. One reason is because ozone has more strong absorption bands in the ultraviolet (UV) than the other common atmospheric gases, and so it dominates radiative transfer in this part of the spectrum. It also has important bands in the infrared. Ozone is extremely chemically active, as a result of which it plays a key role in determining the amounts of other constituents with which it reacts. It follows that ozone will be fairly short-lived; in the stratosphere, the lifetime of a typical atmospheric oz

The methodology is based on studying the degradation of galvanized armor wires (a) during logging operations in a wellbore environment involving aqueous drilling fluids and elevated temperatures and (b) under accelerated atmospheric conditions simulating cable storage in hot and humid environments.

Abstract The economic impact of corrosion on metallic structures is a matter of great relevance throughout the world. More than half of the considerable damage due to corrosion is a result of atmospheric impacts on materials, which is logical considering that the majority of the metallic equipment and structures operate in an atmospheric environment. A need for better understanding of corrosion processes leads to an increased demand for numerical corrosion models, which become increasingly relevant towards simulation, lifetime predictions and optimization of the corrosion prevention.

Abstract Uncatalyzed titanium is shown to be usable under some cathodic protection (CP) applications. At high current densities, such as those employed in NACE Standard Test Method TMO294-94, passivation of uncatalyzed titanium occurs as expected. However, the non-linear nature of the current density versus time relationship can lead to significant lifetimes when the uncatalyzed titanium anode is operated at current densities approaching typical CP applications. Predicted lifetimes at current densities typically used in impressed current CP applications are sensitive to the history of the tita

Abstract The degradation of type 3013 storage containers fabricated from stainless steel is a potential problem for fifty-year storage of stabilized plutonium-bearing materials. Container materials and their welds will be exposed to stress, ionizing radiation, elevated temperatures, embrittling agents (e.g., gallium and plutonium), chloride-containing compounds, and moisture. All of these environmental conditions have been shown to be deleterious to material integrity under certain conditions. In light of these environmental conditions, the three most probable failure modes for the 3013 contai

Abstract Offshore assets such as those found on wind farms are being designed to have extended lifetimes of more than 40 years to offer a sustainable form of energy generation. With offshore maintenance considered a hazardous and expensive process, owners are looking for low or maintenance free solutions to protect their assets. The challenge to the coating manufacturer is twofold, firstly to design a coating system that offers a maintenance free solution in a highly corrosive environment and secondly demonstrating long term performance. This paper will describe a 40-year case history of a coa

Abstract Sensitization of 5xxx series aluminum alloys is a significant concern for the U.S. Navy as the alloys have found use in a variety of ship structures for improved strength-to-weight ratios and enhanced corrosion resistance. Sensitization occurs when precipitates of β-phase magnesium aluminide form at grain boundaries when 5xxx alloys are exposed to elevated temperatures for prolonged periods. These β-phase precipitates are anodic relative to the aluminum matrix and corrode rapidly in the presence of an aggressive electrolyte. This corrosion can result in large crack formation under app

Abstract Atmospheric corrosion of steels, aluminum alloys, and Al-clad aluminum alloys is a problem for commercial and military vehicles and aircraft. Paints and other coatings are usually the primary means to prevent the corrosion of automobiles, trucks, and aircraft. Under ideal conditions, the coating provides a continuous layer that is impervious to moisture. At present, maintenance cycles for commercial and military aircraft and ground vehicles is based on experience and appearance rather than a quantitative determination of coating integrity.

The theory of near-surface atmospheric wind noise is largely predicated on assuming turbulence is homogeneous and isotropic. For high turbulent wavenumbers, this is a fairly reasonable approximation, though it can introduce non-negligible errors in shear flows. Recent near-surface measurements of atmospheric turbulence suggest that anisotropic turbulence can be adequately modeled by rapid-distortion theory (RDT), which can serve as a natural extension of wind noise theory. Here, a solution for the RDT equations of unidirectional plane shearing of homogeneous turbulence is reproduced. It is ass

Air pollution has become a major public issue and it is now evident that unburned hydrocarbons, CO, and NOx must meet increasingly restrictive standards. The emissions of nitrogen oxides by gas turbines are of concern because of their high toxicity and their role in the formation of photochemical smog. The formation of NOx occurs in a gas-fired gas turbine when combustion temperatures exceed a critical level for sufficient time to allow atmospheric nitrogen and oxygen to combine. For those gas turbine applications where steam or ultra-pure water are readily available, then steam or water injec

Reducing methane (CH4) emissions is key to near-term efforts to limit global warming. CH4 is the second most abundant anthropogenic greenhouse gas (GHG) in the atmosphere after carbon dioxide (CO2). The production, transport, and consumption of fossil fuels, in addition to waste and agriculture, account for most anthropogenic CH4 emissions globally (IPCC 2018). Although CH4has only a 12-year lifetime in the atmosphere, it is 84 times more potent per ton than CO2 in a 20-year period and 28 times more potent in a 100-year period (IPCC 2018).

High pressure EGR provides NOx emission reduction even at low exhaust temperatures. To maintain a safe EGR system operation over a required lifetime, the EGR cooler fouling must not exceed an allowable level, even if the engine is operated under worst-case conditions. A reliable fouling simulation model represents a valuable tool in the engine development process, which validates operating and calibration strategies regarding fouling tendency, helping to avoid fouling issues in a late development phase close to series production. Long-chained hydrocarbons in the exhaust gas essentially impact
