Oceanographic monitoring in Hornsund fjord, Svalbard Earth Syst. Sci. Data (IF 11.4) Pub Date : 2024-05-08 Meri Korhonen, Mateusz Moskalik, Oskar Głowacki, Vineet Jain
Abstract. Several climate-driven processes take place in the Arctic fjords. These include ice-ocean interactions, changes in biodiversity and ocean circulation patterns, as well as coastal erosion phenomena. Conducting long-term oceanographic monitoring in the Arctic fjords is, therefore, essential for better understanding and predicting global environmental shifts. Here we address this issue by introducing

Coral Skeletal Proxy Records Database for the Great Barrier Reef, Australia Earth Syst. Sci. Data (IF 11.4) Pub Date : 2024-05-07 Ariella Kathleen Arzey, Helen V. McGregor, Tara R. Clark, Jody M. Webster, Stephen E. Lewis, Jennie Mallela, Nicholas P. McKay, Hugo W. Fahey, Supriyo Chakraborty, Tries B. Razak, Matt J. Fischer
Abstract. The Great Barrier Reef (GBR), Australia has a long history of palaeoenvironmental coral research. However, it can be logistically difficult to find the relevant research and records, which are often unpublished or exist as ‘grey literature’. This hinders researchers’ ability to efficiently assess the current state of coral core studies on the GBR and thus identify any key knowledge gaps.

Marsden, Michael Flynn, Kezhen Hu, Navaneeth M. Thamban, Paul I. Williams, Paul J. Connolly
Abstract. Cloud feedbacks associated with deep convective anvils remain highly uncertain. In part, this uncertainty arises from a lack of understanding of how microphysical processes influence the cloud radiative effect. In particular, climate models have a poor representation of microphysics processes, thereby encouraging the collection and study of observation data to enable better representation

Nilsson, Matthias Peichl, Oliver Sonnentag, Eeva-Stiina Tuittila, Torsten Sachs
Abstract. Wetlands are the largest natural source of methane (CH4) emissions globally. Northern wetlands (>45° N), accounting for 42 % of global wetland area, are increasingly vulnerable to carbon loss, especially as CH4 emissions may accelerate under intensified high-latitude warming. However, the magnitude and spatial patterns of high-latitude CH4 emissions remain relatively uncertain. Here we present

LegacyVegetation 1.0: Global reconstruction of vegetation composition and forest cover from pollen archives of the last 50 ka Earth Syst. Sci. Data (IF 11.4) Pub Date : 2024-04-02 Laura Schild, Peter Ewald, Chenzhi Li, Raphaël Hébert, Thomas Laepple, Ulrike Herzschuh
Abstract. With rapid anthropogenic climate change future vegetation trajectories are uncertain. Climate-vegetation models can be useful for predictions but need extensive data on past vegetation for validation and improving systemic understanding. Even though pollen data provide a great source of this information, the data is compositionally biased due to differences in taxon-specific relative pollen

Discrete Global Grid System-based Flow Routing Datasets in the Amazon and Yukon Basins Earth Syst. Sci. Data (IF 11.4) Pub Date : 2024-04-02 Chang Liao, Darren Engwirda, Matthew Cooper, Mingke Li, Yilin Fang
Abstract. Discrete Global Grid systems (DGGs) are emerging spatial data structures widely used to organize geospatial datasets across scales. While DGGs have found applications in various scientific disciplines, including atmospheric science and ecology, their integration into physically based hydrologic models and Earth System Models (ESMs) has been hindered by the lack of flow-routing datasets based

Deriving a Transformation Rate Map of Dissolved Organic Carbon over the Contiguous U.S. Earth Syst. Sci. Data (IF 11.4) Pub Date : 2024-04-02 Lingbo Li, Hong-Yi Li, Guta Abeshu, Jinyun Tang, L. Ruby Leung, Chang Liao, Zeli Tan, Hanqin Tian, Peter Thornton, Xiaojuan Yang
Abstract. Riverine dissolved organic carbon (DOC) plays a vital role in regional and global carbon cycles. However, the processes of DOC conversion from soil organic carbon (SOC) and leaching into rivers are insufficiently understood, inconsistently represented, and poorly parameterized, particularly in land surface and earth system models. As a first attempt to fill this gap, we propose a generic

Constructing a measurement-based spatially explicit inventory of US oil and gas methane emissions Earth Syst. Sci. Data (IF 11.4) Pub Date : 2024-04-02 Mark Omara, Anthony Himmelberger, Katlyn MacKay, James P. Williams, Joshua Benmergui, Maryann Sargent, Steven C. Wofsy, Ritesh Gautam
Abstract. Accurate and comprehensive quantification of oil and gas methane emissions is pivotal in informing effective methane mitigation policies, while also supporting the assessment and tracking of progress towards emissions reduction targets set by governments and industry. While national bottom-up source-level inventories are useful for understanding the sources of methane emissions, they are

PM2.5 concentrations based on near-surface visibility at 4011 sites in the Northern Hemisphere from 1959 to 2022 Earth Syst. Sci. Data (IF 11.4) Pub Date : 2024-04-02 Hongfei Hao, Kaicun Wang, Guocan Wu, Jianbao Liu, Jing Li
Abstract. Long-term PM2.5 data are needed to study the atmospheric environment, human health, and climate change. PM2.5 measurements are sparsely distributed and of short duration. In this study, daily PM2.5 concentrations are estimated from 1959 to 2022 using a machine learning method at 4011 terrestrial sites in the Northern Hemisphere based on hourly atmospheric visibility data, which are extracted

Harmonized European Union subnational crop statistics can reveal climate impacts and crop cultivation shifts Earth Syst. Sci. Data (IF 11.4) Pub Date : 2024-03-27 Giulia Ronchetti, Luigi Nisini Scacchiafichi, Lorenzo Seguini, Iacopo Cerrani, Marijn van der Velde
Abstract. The availability of coherent time series of crop statistics is essential for better analyzing the past, understanding the present, and predicting future trends in yield, area, and production. Importantly, such data also underpin assessments and subsequent policy actions that can shape future food systems that are more resilient in the face of climate change and that are sustainable in terms

A Climate Data Record of Stratospheric Aerosols Earth Syst. Sci. Data (IF 11.4) Pub Date : 2024-03-27 Viktoria F. Sofieva, Alexei Rozanov, Monika Szelag, John P. Burrows, Christian Retscher, Robert Damadeo, Doug Degenstein, Landon A. Rieger, Adam Bourassa
Abstract. Climate-related studies need information about the distribution of stratospheric aerosols, which influence the energy balance of the Earth’s atmosphere. In this work, we present a merged dataset of vertically resolved stratospheric aerosol extinction coefficients, which is derived from data by six limb and occultation satellite instruments: SAGE II on ERBS, GOMOS and SCIAMACHY on Envisat

HiQ-LAI: a high-quality reprocessed MODIS leaf area index dataset with better spatiotemporal consistency from 2000 to 2022 Earth Syst. Sci. Data (IF 11.4) Pub Date : 2024-03-26 Kai Yan, Jingrui Wang, Rui Peng, Kai Yang, Xiuzhi Chen, Gaofei Yin, Jinwei Dong, Marie Weiss, Jiabin Pu, Ranga B. Myneni
Abstract. Leaf area index (LAI) is a crucial parameter for characterizing vegetation canopy structure and energy absorption capacity. The Moderate Resolution Imaging Spectroradiometer (MODIS) LAI has played a significant role in landmark studies due to its clear theoretical basis, extensive historical time series, extensive validation results, and open accessibility. However, MODIS LAI retrievals are

SEA-Rice-Ci10: High-resolution Mapping of Rice Cropping Intensity and Harvested Area Across Southeast Asia using the Integration of Sentinel-1 and Sentinel-2 Data Earth Syst. Sci. Data (IF 11.4) Pub Date : 2024-03-25 Frisa Irawan Ginting, Rudiyanto Rudiyanto, Fatchurahman,, Ramisah Mohd Shah, Norhidayah Che Soh, Sunny Goh Eng Giap, Dian Fiantis, Budi Indra Setiawan, Sam Schiller, Aaron Davitt, Budiman Minasny
Abstract. The Southeast Asia region has a vast expanse with diverse tropical climates, making it a prominent centre of rice cultivation, contributing to about 20 % of the world’s rice production and contributes 29 % of global rice methane emissions. As a staple food for many countries, accurate and up-to-date information on the rice harvested area is crucial for addressing food security issues, predicting
