Published: July 2023

Abstract. The weather information value chain provides a framework for characterising the production, communication, and use of information by all stakeholders in an end-to-end warning system covering weather and hazard monitoring, modelling and forecasting, risk assessment, communication and preparedness activities. Warning services are typically developed and provided through a multitude of complex and malleable value chains (networks), often established through co-design, co-creation and co-provision. In November 2020, a 4-year international project under the World Meteorological Organization (WMO) World Weather Research Programme was instigated to explore value chain approaches to describe and evaluate
warning systems for high impact weather by integrating physical and social
science. It aims to create a framework with guidance and tools for using
value chain approaches, and to develop a database of high impact weather
warning case studies for scientists and practitioners to review, analyse and
learn from previous experience using value chain approaches. Here we describe a template for high-impact weather event case study
collection that provides a tool for scientists and practitioners involved in
researching, designing and evaluating weather-related warning systems to
review previous experience of high impact weather events and assess their
efficacy.
Implementing a coral reef CaCO3 production module in the iLOVECLIM climate model
Authors: Bouttes Nathaelle , Kwiatkowski Lester , Berger Manon , Brovkin Victor , Munhoven Guy
Published: July 2023

Abstract. Coral reef development is intricately linked to both climate and the concentration of atmospheric CO2, specifically through temperature and carbonate chemistry in the upper ocean. In turn, the calcification of corals modifies the concentration of dissolved inorganic carbon and total alkalinity in the ocean, impacting air-sea gas exchange, atmospheric CO2 concentration, and ultimately the climate. This retroaction between atmospheric conditions and coral biogeochemistry can only be accounted for with a coupled coral-carbon-climate model. Here we present the implementation of a coral reef calcification module into an Earth System model. Simulated coral reef production of the calcium carbonate mineral aragonite depends on photosynthetically active radiation, nutrient concentrations, salinity, temperature and the aragonite saturation state. An ensemble of 210 parameter perturbation simulations was performed to identify carbonate production parameter values that optimise the simulated distribution of coral reefs and associated carbonate production. The tuned model simulates the presence of coral reefs and regional-to-global carbonate production values in good agreement with data-based estimates. The model enables assessment of past and future coral-climate coupling on seasonal to millennial timescales, highlighting how climatic trends and variability may affect reef development and the resulting climate-carbon feedback.
A new inventory of High Mountain Asia surging glaciers derived from multiple elevation datasets since the 1970s
Authors: Guo Lei , Li Jia , Dehecq Amaury , Li Zhiwei , Li Xin , Zhu Jianjun
Published: July 2023

Abstract. Glacier surging is an unusual instability of ice flow, and inventories of surging glaciers are important for regional glacier mass
balance studies and glacier dynamic studies. Glacier surges in High Mountain
Asia (HMA) have been widely reported. However, the completeness of available
inventories of HMA surging glaciers is hampered by the insufficient spatial
and temporal coverage of glacier change observations or by the limitations
of the identification methods. In this study, we established a new inventory
of HMA surging glaciers based on glacier surface elevation changes and
morphological changes over 4 decades. Three elevation change datasets
based on four elevation sources (the KH-9 DEM, NASA DEM, COP30 DEM, and HMA
DEM) and long-term Landsat satellite image series were utilized to assess
the presence of typical surge features over two time periods (1970s–2000 and 2000–2020). A total of 890 surging and 336 probably or possibly surging glaciers were identified in HMA. Compared to the most recent inventory of surging glaciers in HMA, our inventory incorporated 253 previously unidentified surging glaciers. The number and area of surging glaciers accounted for ∼2.49 % (excluding glaciers smaller than 0.4 km2) and ∼16.59 % of the total glacier number and
glacier area in HMA, respectively. Glacier surges were found in 21 of the 22 subregions of HMA (except for the Dzhungarsky Alatau); however, the density of surging glaciers is highly uneven. Glacier surges occur frequently in the northwestern subregions (e.g., Pamir and Karakoram) but less often in the peripheral subregions. The inventory further shows that surge activity is more likely to occur for glaciers with a larger area, longer length, and wider elevation range. Among glaciers with similar areas, the surging ones usually have steeper slopes than non-surging ones. The inventory and elevation change products of identified surging glaciers are available at https://doi.org/10.5281/zenodo.7961207 (Guo et al., 2023).
GRiMeDB: the Global River Methane Database of concentrations and fluxes

Published: July 2023

Abstract. Despite their small spatial extent, fluvial ecosystems play a significant role in processing and transporting carbon in aquatic networks, which
results in substantial emission of methane (CH4) into the atmosphere. For this reason, considerable effort has been put into identifying patterns and drivers of CH4 concentrations in streams and rivers and estimating fluxes to the atmosphere across broad spatial scales. However, progress toward these ends has been slow because of pronounced spatial and temporal variability of lotic CH4 concentrations and fluxes and
by limited data availability across diverse habitats and physicochemical conditions. To address these challenges, we present a comprehensive
database of CH4 concentrations and fluxes for fluvial ecosystems along with broadly relevant and concurrent physical and chemical
data. The Global River Methane Database (GriMeDB; https://doi.org/10.6073/pasta/f48cdb77282598052349e969920356ef, Stanley et al., 2023) includes 24 024 records of CH4 concentration and 8205 flux measurements from 5029 unique sites derived from publications, reports, data repositories,
unpublished data sets, and other outlets that became available between 1973 and 2021. Flux observations are reported as diffusive, ebullitive, and
total CH4 fluxes, and GriMeDB also includes 17 655 and 8409 concurrent measurements of concentrations and 4444 and 1521 fluxes for carbon dioxide (CO2) and nitrous oxide (N2O), respectively. Most observations are date-specific (i.e., not site averages), and many are supported by data for 1 or more of 12 physicochemical variables and 6 site variables. Site variables include codes to characterize marginal channel types
(e.g., springs, ditches) and/or the presence of human disturbance (e.g., point source inputs, upstream dams). Overall, observations in GRiMeDB encompass the broad range of the climatic, biological, and physical conditions that occur among world river basins, although some geographic gaps remain (arid
regions, tropical regions, high-latitude and high-altitude systems). The global median CH4 concentration (0.20 µmol L−1) and diffusive flux (0.44 mmolm-2d-1) in GRiMeDB are lower than estimates from prior site-averaged compilations, although ranges
(0 to 456 µmol L−1 and −136 to 4057 mmolm-2d-1) and standard deviations (10.69 and 86.4) are greater for this larger and more temporally resolved database. Available flux data are dominated by diffusive measurements despite the recognized importance of ebullitive
and plant-mediated CH4 fluxes. Nonetheless, GriMeDB provides a comprehensive and cohesive resource for examining relationships between
CH4 and environmental drivers, estimating the contribution of fluvial ecosystems to CH4 emissions, and contextualizing site-based investigations.
Developing spring wheat in the Noah-MP land surface model (v4.4) for growing season dynamics and responses to temperature stress

Published: July 2023

Abstract. The US Northern Great Plains and the Canadian Prairies
are known as the world's breadbaskets for their large spring wheat production
and exports to the world. It is essential to accurately represent spring
wheat growing dynamics and final yield and improve our ability to predict
food production under climate change. This study attempts to incorporate
spring wheat growth dynamics into the Noah-MP crop model for a long time
period (13 years) and fine spatial scale (4 km). The study focuses on three
aspects: (1) developing and calibrating the spring wheat model at
a point scale, (2) applying a dynamic planting and harvest date to facilitate
large-scale simulations, and (3) applying a temperature stress function to
assess crop responses to heat stress amid extreme heat. Model results are
evaluated using field observations, satellite leaf area index (LAI), and
census data from Statistics Canada and the United States Department of Agriculture
(USDA). Results suggest that incorporating a dynamic planting and harvest
threshold can better constrain the growing season, especially the peak
timing and magnitude of wheat LAI, as well as obtain realistic yield
compared to prescribing a static province/state-level map. Results also
demonstrate an evident control of heat stress upon wheat yield in three
Canadian Prairies Provinces, which are reasonably captured in the new
temperature stress function. This study has important implications in terms of
estimating crop yields, modeling the land–atmosphere interactions in agricultural areas, and predicting crop growth responses to increasing temperatures amidst
climate change.

Abstract. Quantifying soil redistribution rates is a global challenge addressed with
direct sediment measurements (e.g. traps), models, and isotopic, geochemical,
and radionuclide tracers. The isotope of plutonium, namely 239+240Pu,
is a relatively new soil redistribution tracer in this challenge. Direct
validation of 239+240Pu as a soil redistribution tracer is, however, still
missing. We used a unique sediment yield time series in southern Italy,
reaching back to the initial fallout of 239+240Pu to verify
239+240Pu as a soil redistribution tracer. Distributed soil samples
(n=55) were collected in the catchment, and at undisturbed reference sites
(n=22), 239+240Pu was extracted, measured with inductively coupled plasma mass spectrometry (ICP-MS), and converted
to soil redistribution rates. Finally, we used a generalized additive model
(GAM) to regionalize soil redistribution estimates for the catchment. For
the catchment sites, mean 239+240Pu inventories were significantly
reduced (16.8 ± 10.2 Bq m−2) compared to the reference inventory
(40.5 ± 3.5 Bq m−2), indicating the dominance of erosion.
Converting these inventory losses into soil erosion rates resulted in an
average soil loss of 22.2 ± SD 7.2 t ha−1 yr−1. The
uncertainties of the approach stemmed mainly from the high measurement
uncertainties of some low-activity samples where samples have been bulked
over depth. Therefore, we recommend taking incremental soil samples and
extracting larger soil volumes (∼ 20 g). The geographic
coordinates and the flow accumulation best described the spatial pattern of
erosion rates in the GAM model. Using those predictors to upscale Pu-derived
soil redistribution rates for the entire catchment resulted in an average
on-site loss of 20.7 t ha−1 yr−1, which corresponds very well to
the long-term average sediment yield of 18.7 t ha−1 yr−1 measured at the catchment outlet and to 137Cs-derived soil
redistribution rates. Overall, this comparison of Pu-derived soil
redistribution rates with measured sediment yield data validates
239+240Pu as a suitable retrospective soil redistribution tracer.

Abstract. Improvements in the resolution of sea-floor mapping
techniques have revealed extremely regular, sub-metre-scale ridge landforms
produced by the tidal flexure of ice-shelf grounding lines as they retreated
very rapidly (i.e. at rates of several kilometres per year). Guided by such
novel sea-floor observations from Thwaites Glacier, West Antarctica, we
present three mathematical models for the formation of these corrugation
ridges at a tidally migrating grounding line (that is retreating at a
constant rate), where each ridge is formed by either constant till flux to
the grounding line, till extrusion from the grounding line, or the
resuspension and transport of grains from the grounding-zone bed. We find
that both till extrusion (squeezing out till like toothpaste as the ice
sheet re-settles on the sea floor) and resuspension and transport of
material can qualitatively reproduce regular, delicate ridges at a
retreating grounding line, as described by sea-floor observations. By
considering the known properties of subglacial sediments, we agree with
existing schematic models that the most likely mechanism for ridge formation
is till extrusion at each low-tide position, essentially preserving an
imprint of the ice-sheet grounding line as it retreated. However, when
realistic (shallow) bed slopes are used in the simulations, ridges start to
overprint one another, suggesting that, to preserve the regular ridges that
have been observed, grounding line retreat rates (driven by dynamic
thinning?) may be even higher than previously thought.

Abstract. The Arctic Ocean is generally undersaturated in CO2 and acts as a net sink of atmospheric CO2. This oceanic uptake is strongly modulated by sea ice, which can prevent air–sea gas exchange and has major impacts on stratification and primary production. Moreover, carbon is stored in sea ice with a ratio of alkalinity to dissolved inorganic carbon that is larger than in seawater. It has been suggested that this storage amplifies the seasonal cycle of seawater pCO2 and leads to an increase in oceanic carbon uptake in seasonally ice-covered regions compared to those that are ice-free. Given the rapidly changing ice scape in the Arctic Ocean, a better understanding of the link between the seasonal cycle of sea ice and oceanic uptake of CO2 is needed. Here, we investigate how the storage of carbon in sea ice affects the air–sea CO2 flux and quantify its dependence on the ratio of alkalinity to inorganic carbon in ice. To this end, we present two independent approaches: a theoretical framework that provides an analytical expression of the amplification of carbon uptake in seasonally ice-covered oceans and a simple parameterization of carbon storage in sea ice implemented in a 1D physical–biogeochemical ocean model. Sensitivity simulations show a linear relation between ice melt and the amplification of seasonal carbon uptake. A 30 % increase in carbon uptake in the Arctic Ocean is estimated compared to ice melt without amplification. Applying this relationship to different future scenarios from an earth system model that does not account for the effect of carbon storage in sea ice suggests that Arctic Ocean carbon uptake is underestimated by 5 % to 15 % in these simulations.

Abstract. Antarctic coastal polynyas produce dense shelf water, a primary source of Antarctic Bottom Water that contributes to the global overturning
circulation. This paper investigates Antarctic dense water formation in the high-resolution version of the Energy Exascale Earth System Model
(E3SM-HR). The model is able to reproduce the main Antarctic coastal polynyas, although the polynyas are smaller in area compared to
observations. E3SM-HR also simulates several occurrences of open-ocean polynyas (OOPs) in the Weddell Sea at a higher rate than what the last
50 years of the satellite sea ice observational record suggests, but similarly to other high-resolution Earth system model simulations. Furthermore,
the densest water masses in the model are formed within the OOPs rather than on the continental shelf as is typically observed. Biases related to
the lack of dense water formation on the continental shelf are associated with overly strong atmospheric polar easterlies, which lead to a strong
Antarctic Slope Front and too little exchange between on- and off-continental shelf water masses. Strong polar easterlies also produce excessive
southward Ekman transport, causing a build-up of sea ice over the continental shelf and enhanced ice melting in the summer season. This, in turn,
produces water masses on the continental shelf that are overly fresh and less dense relative to observations. Our results indicate that high
resolution alone is insufficient for models to properly reproduce Antarctic dense water; the large-scale polar atmospheric circulation around
Antarctica must also be accurately simulated.

La Unidad de Cultura Científica de la Universidad de Burgos (UBU) puso en marcha, en el año 2016, un programa televisivo de divulgación científica em el canal de televisión “La 8 Burgos”, y en el canal La 7 Castilla y León, de ámbito regional. El programa denominado “Cien&Cía” tiene una misión primordial que es la difusión de la investigación científica que se realiza en la Universidad de Burgos. El crecimiento del programa y una importante visión de futuro han hecho que este espacio televisivo cuente con más colaboradores de ámbito nacional, secciones y contenidos que tratan también temas científicos que superan la barrera de la investigación en la Universidad de Burgos. La estrategia de difusión de este programa que se há mantenido desde su estreno, no solo es la emisión televisiva sino también la promoción de sus contenidos en Youtube a través del canal de La 8 Burgos y de TVUBU, televisión de la Universidad de Burgos, sino también a través de informaciones situadas en otras redes sociales como Facebook y Twitter. No solo la emisión televisiva ha contado con respaldo de la audiencia; también las audiencias de redes sociales han seguido las emisiones de cada uno de los programas y han comentado los contenidos de forma activa. En esta última temporada cuyas emisiones finalizaron en el mes de julio de 2022, se han incluido vídeos cortos de Youtube, como veremos a continuación, también han tenido buena acogida por parte del público digital.
