Abstract. Urban conurbations of East Africa are affected by harmful
levels of air pollution. The paucity of local air quality networks and the
absence of the capacity to forecast air quality make difficult to quantify the
real level of air pollution in this area. The CHIMERE chemistry transport model has been used along with the Weather Research and Forecasting (WRF) meteorological model to run high-spatial-resolution (2 × 2 km)
simulations of hourly concentrations of particulate matter with an aerodynamic
diameter smaller than 2.5 µm (PM2.5) for three East African urban
conurbations: Addis Ababa in Ethiopia, Nairobi in Kenya, and Kampala in
Uganda. Two existing emission inventories were combined to test the
performance of CHIMERE as an air quality model for a target monthly period
in 2017, and the results were compared against observed data from urban, roadside,
and rural sites. The results show that the model is able to reproduce hourly
and daily temporal variabilities in aerosol concentrations that are close to
observed values from urban, roadside, and rural environments. CHIMERE's
performance as a tool for managing air quality was also assessed. The
analysis demonstrated that, despite the absence of high-resolution data and
up-to-date biogenic and anthropogenic emissions, the model was able to
reproduce 66 %–99 % of the daily PM2.5 exceedances above the World Health Organization (WHO)
24 h mean PM2.5 guideline (25 µg m−3) in the three
cities. An analysis of the 24 h average PM2.5 levels was also
carried out for 17 constituencies in the vicinity of Nairobi. This showed
that 47 % of the constituencies in the area exhibited a poor Air Quality
Index for PM2.5 that was in the unhealthy category for human health, thereby exposing
between 10 000 and 30 000 people per square kilometre to harmful levels of air
contamination.
Investigating the loess–palaeosol sequence of Bahlingen-Schönenberg (Kaiserstuhl), southwestern Germany, using a multi-methodological approach

Published: August 2022

Abstract. Loess–palaeosol sequences (LPSs) are key archives for the
reconstruction of Quaternary environmental conditions, but there is a lack
of investigated records from the southern Upper Rhine Graben (southwestern Germany).
To close this gap, a LPS at Bahlingen-Schönenberg was investigated at
high resolution using a multi-method approach. Infrared stimulated
luminescence screening reveals a major hiatus in the lower part of the LPS
that according to luminescence dating is older than marine isotope stage
(MIS) 4. The section above the hiatus formed by quasi-continuous loess
sedimentation between ca. 34 and 27 ka, interrupted by phases of weak
reductive pedogenesis. The fact that this pedogenesis is much weaker
compared to corresponding horizons in the more northerly part of the Upper
Rhine Graben could be due to regionally drier conditions caused by a
different atmospheric circulation pattern at the time of deposition. Our
results reinforce earlier notions that the major environmental shifts
leading into the Last Glacial Maximum (LGM) of southern Central Europe
significantly predate the transition of MIS 3 to 2 (ca. 29 ka). In
particular, the last massive phase of loess accumulation started several
thousand years prior to the arrival of glaciers in the foreland of the Alps,
which raises questions regarding the source and transport paths of the dust.
It is also noted that no loess dating to the LGM or the time thereafter was
observed due to either a lack of deposition or later erosion.
Estimating return intervals for extreme climate conditions related to winter disasters and livestock mortality in Mongolia

Published: August 2022

Abstract. Mass livestock mortality events during severe winters, a phenomenon that Mongolians call dzud, cause the country significant socioeconomic problems. Dzud is an example of a compound event, meaning that multiple climatic and social drivers contribute to the risk of occurrence. Existing studies argue that the frequency and intensity of dzud events are rising due to the combined effects of climate change and variability, most notably summer drought and severe winter conditions, on top of socioeconomic dynamics such as overgrazing. Summer droughts are a precondition for dzud because scarce grasses cause malnutrition, making livestock more vulnerable to harsh winter conditions. However, studies investigating the association between climate and dzud typically look at a short time frame (i.e., after 1940), and few have investigated the risk or the recurrence of dzud over a century-scale climate record. This study aims to fill the gaps in technical knowledge about the recurrence probability of dzud by estimating the return
periods of relevant climatic variables: summer drought conditions and winter minimum temperature. We divide the country into three regions (northwest, southwest, and east Mongolia) based on the mortality index at the soum (county) level. For droughts, our study uses as a proxy the tree-ring-reconstructed Palmer drought severity index (PDSI) for three regions between 1700–2013. For winter severity, our study uses observational data of winter minimum temperature after 1901 while inferring winter minimum temperature in Mongolia from instrumental data in Siberia that extend to the early 19th century. Using a generalized extreme value distribution with time-varying parameters, we find that the return periods of drought conditions vary over time, with variability increasing for all the regions. Winter temperature severity, however, does not change with time. The median temperature of the 100-year return period for winter minimum temperature in Mongolia over the past 300 years is estimated as −26.08 ∘C for the southwest, −27.99 ∘C for the northwest, and −25.31 ∘C for the east. The co-occurrence of summer drought and winter severity increases in all the regions in the early 21st century. The analysis suggests that a continued trend in summer drought would lead to increased vulnerability and malnutrition. Prospects for climate index insurance for livestock are also discussed.
An efficient probabilistic workflow for estimating induced earthquake parameters in 3D heterogeneous media
Authors: Masfara La Ode Marzujriban , Cullison Thomas , Weemstra Cornelis 
Published: August 2022

Abstract. We present an efficient probabilistic workflow for the estimation of source parameters of induced seismic events in three-dimensional heterogeneous
media. Our workflow exploits a linearized variant of the Hamiltonian Monte Carlo (HMC) algorithm. Compared to traditional Markov chain Monte Carlo
(MCMC) algorithms, HMC is highly efficient in sampling high-dimensional model spaces. Through a linearization of the forward problem around the
prior mean (i.e., the “best” initial model), this efficiency can be further improved. We show, however, that this linearization leads to a
performance in which the output of an HMC chain strongly depends on the quality of the prior, in particular because not all (induced) earthquake
model parameters have a linear relationship with the recordings observed at the surface. To mitigate the importance of an accurate prior, we
integrate the linearized HMC scheme into a workflow that (i) allows for a weak prior through linearization around various (initial) centroid
locations, (ii) is able to converge to the mode containing the model with the (global) minimum misfit by means of an iterative HMC approach, and
(iii) uses variance reduction as a criterion to include the output of individual Markov chains in the estimation of the posterior probability. Using
a three-dimensional heterogeneous subsurface model of the Groningen gas field, we simulate an induced earthquake to test our workflow. We then
demonstrate the virtue of our workflow by estimating the event's centroid (three parameters), moment tensor (six parameters), and the earthquake's origin
time. Using the synthetic case, we find that our proposed workflow is able to recover the posterior probability of these source parameters rather
well, even when the prior model information is inaccurate, imprecise, or both inaccurate and imprecise.

Educação do Campo e Sociolinguística Educacional
Authors: Santos Telma Maria Pereira dos , Da Silva Amorim Fabrício , Santana Bárbara Elaine Correia de 
Published: August 2022

A Educação do Campo constitui uma modalidade de ensino que se assenta no comprometimento com os conhecimentos produzidos pelos sujeitos do campo a partir da legitimação pedagógica de suas práticas socioculturais, de modo que a Escola reconheça e valorize as suas identidades (Cf. CALDART, 2004). A Sociolinguística Educacional, por sua vez, pauta-se pela abordagem pedagógica da variação linguística (Cf. BORTONI-RICARDO, 2005; COAN; FREITAG, 2010; MARTINS; VIEIRA; TAVARES, 2014) para promover uma educação linguística plural e democrática, pela qual, entre outras ações, se combate o preconceito em relação às variedades não padrão, como, por exemplo, os dialetos rurais. O presente trabalho discute essa perspectiva de ensino de língua, no âmbito da Educação do Campo, objetivando circunscrevê-la em um conjunto de práticas político-pedagógicas de natureza decolonial. Nesse sentido, aborda-se o ensino sociolinguístico de português como uma diretriz pedagógica que, sobretudo na Educação do Campo, contribui para coibir a Colonialidade do Saber (QUIJANO, 2005; BABTISTA; LÓPEZ-GOPAR, 2019), isto é, processo – resultante do colonialismo – responsável, entre outros efeitos, por levar a Escola a endossar, no processo de ensino-aprendizagem, uma cosmovisão eurocêntrica em detrimento de identidades linguístico-culturais locais, como as dos sujeitos do campo.
