title: Rockglacier inventory of the Western Nyainqêntanglha Range, Tibetan Plateau

description: The western Nyainqêntanglha Range on the Tibetan Plateau reaches an elevation of 7162 m and is characterized by an extensive periglacial environment. Here, we present the first rock glacier inventory of this region containing 1433 rock glaciers over an area of 4622 km². To create the most reliable inventory we combine manually created rock glacier outlines with an automated classification approach. The manual outlines were generated based on surface elevation data, optical satellite imagery and a surface velocity model. The surface velocity model was generated via InSAR time series analysis with Sentinel-1 data from 2016 to 2019. The rockglacier inventory was compiled in accordance with the guidelines (baseline concepts 4.1 and practical guidelines 3.0.1) from the action group on 'Rock glacier inventories and kinematics' of the International Permafrost Association (IPA).

title: Illimani 2015 firn-core (Bolivia, 6300 m) black carbon record between 1995 to 2015 CE

description: The glacier on Nevado Illimani in the eastern Bolivian Altiplano is one of the few in the mid- to low-latitudes giving access to ice covering the entire Holocene. The impurity and stable isotope in water records extracted from the Illimani ice core contain information on the composition of the past atmosphere and climate conditions over time. Here we provide a continuous high-resolution (median 3 cm water equivalent per sample) record of concentrations of refractory black carbon (rBC) from a 25.7 m long firn core drilled in 2015 named Illimani 2015 (Bolivia, 6300 m asl., 16°38'58.57 S, 67°47'03.57 W) encompassing the period 1995 to 2015 CE. At the Paul Scherrer Institute rBC was analyzed with a Single Particle Soot Photometer (SP2, Droplet Measurement Technologies) and a jet (APEX-Q, Elemental Scientific Inc.) nebulizer to aerosolize the aqueous samples (Osmont et al., 2019). Firn-core dating is based on annual-layer counting and the firn core overlaps with the 139 m deep Illimani99 ice core. This dataset underpins analyses of anthropogenic and natural emissions of aerosol species in South America (Osmont et al., 2019).

title: Colle Gnifetti (Monte Rosa, Alps) CG03B ice-core major ions (sodium, calcium, nitrate, sulfate) and refractory black carbon record between 1040 to 2001 CE

description: The impurity and stable isotope in water records extracted from the Colle Gnifetti ice core (Swiss-Italian Alps, 45°55′50″N, 7°52′33″E, 4455 m asl) contain information on the composition of the past atmosphere and climate conditions over the Holocene. Here we provide a continuous high-resolution (median 2.2 cm per sample) record of concentrations of major ions (Na+, Ca2+, NO3-, SO42-) and refractory black carbon (rBC) from an ice core drilled in 2003 (CG03B) encompassing the period 1040 to 2001 CE. Major ions were determined at the Paul Scherrer Institute using ion-chromatography (850 Professional IC, Metrohm), and rBC was analyzed with a Single Particle Soot Photometer (SP2, Droplet Measurement Technologies) and a jet (APEX-Q, Elemental Scientific Inc.) nebulizer to aerosolize the aqueous samples (Sigl et al., 2018). Ice-core dating is based on synchronization against a parallel ice core (CG03A; Sigl et al., 2009). This dataset underpins analyses of anthropogenic and natural emissions of aerosol species over the industrial (Sigl et al., 2018; Eckhardt et al., 2023) and pre-industrial periods (Brugger et al., 2021) and can serve as a benchmark for bottom-up emission inventories based on energy consumption.

title: Glacier calving front locations for the Antarctic Peninsula Ice Sheet derived from remote sensing and deep learning from 2013 to 2023

description: Glacier calving front positions have been derived by applying a deep learning method to multispectral Landsat-8 and Landsat-9 imagery. The record contains 4817 calving front positions across 42 outlet glaciers of the Antarctic Peninsula from October 2013 to April 2023. Due to the high temporal resolution of this data product it provides unique opportunities to study seasonal and sub-seasonal terminus changes. Calving front locations are important for (1) studying and understanding ice-ocean interaction; (2) mapping glacier area change; and (3) constraining ice dynamicmodels. The following glaciers are included in this data record: Akaga-Sinion Glacier system, Avsyuk Glacier, Birley Glacier, Bleriot Glacier, Boydell Glacier, Cadman Glacier, Carlson Glacier, Cayley Glacier, Clarke Glacier, Crane Glacier, Darvari-Boryana-Desudava Glacier system, Dinsmore-Bombardier-Edgeworth Glacier system, Drygalski Glacier, Drummond Glacier, Erskine Glacier, Fleming Glacier, Funk Glacier, Hariot Glacier, Heim Glacier, Hektoria-Green-Evans Glacier system, Hopkins Glacier, Hugi Glacier, Jorum Glacier, Keith Glacier, Malorad Glacier, McCance Glacier, Murphy Wilkinson Glacier, Otlet Glacier, Peter Glacier, Prospect Glacier, Punchbowl Glacier, Pyke Glacier, Remus-Snowshoe Glacier, Renard-Krebs Glacier, Sjogren Glacier, Stringfellow Glacier, Swithinbank Glacier, Temple Glacier, Trooz Glacier, Valot Glacier, Widdowson Glacier and Zaychar Glacier.

title: Colle Gnifetti (Monte Rosa, Alps) ice-core glaciochemical and trace element records between 950 to 2015 CE

description: The impurity and stable isotope in water records extracted from the Colle Gnieffti ice core (Swiss-Italian Alps, 45°55′50″N, 7°52′33″E, 4455 m asl) contain information on the composition of the past atmosphere and climate conditions over the Holocene. Here we provide annual mean concentrations of major ions (Na+, NH4+, K+, Mg2+, Ca2+, Cl-, NO3-, SO42-), refractory black carbon (rBC) and trace elements (Al, Mn, Fe, Sr, Rb, V, Cr, Ba, Pb, Bi, Cd) next to the isotopic composition of water (i.e. d18O) from a stack of 2 firn cores drilled in 2008 and 2015 (CG15, CG08) and two parallel deep ice cores drilled in 2003 (CG03A, CG03B) encompassing the period 950 to 2015 CE. Major ions were determined at the Paul Scherrer Institute using ion chromatography (with Dionex and Metrohm systems) and rBC was analyzed with a Single Particle Soot Photometer (SP2, Droplet Measurement Technologies) and a jet (APEX-Q, Elemental Scientific Inc.) nebulizer to aerosolize the aqueous samples (Sigl et al., 2018). Trace elements were analyzed at the University of Venice using a continuous ice- core melting device coupled to an Agilent 7500 quadrupole inductively coupled plasma mass spectrometer (ICP-Q-MS) and a Element2 (Thermo-Finnigan) sector field inductively coupled plasma mass spectrometer (ICP-SFMS) with discrete sampling (Gabrieli et al., 2011, 2014; Sigl et al., 2018). Stable isotopes of water were measured at the Paul Scherrer Institute by isotope ratio mass spectrometry (IRMS) using a Delta Plus XP (Finnigan MAT) system. Analytical uncertainties were ±0.1 ‰ for d18O. Annual mean concentrations and the mean annual isotopic composition of the water were calculated by averaging all samples within each year. Samples below the detection limit were set to 50 % of the value of the detection limit. Ice-core dating is based between 1763 and 2015 CE on annual-layer counting, constrained by historic Saharan dust events and volcanic eruption signals. Before 1741 CE the dating is based on a simple glacier flow model fitted to radiocarbon dates of particulate carbonaceous aerosols embedded in the ice (Jenk et al., 2009; Sigl et al., 2009). A polynomial regression is used to merge both age models between 1763 and 1741 CE. These datasets underpin analyses of anthropogenic and natural emissions of aerosol species over the industrial (Sigl et al., 2018; Gabrieli et al., 2011; Eckhardt et al., 2023) and pre-industrial periods (Brugger et al., 2021; Gabrieli et al., 2014).

title: Tree inventory dataset of floodplain forest, Leipzig, Germany

description: Leipzig is the only major German city in which extensive hardwood floodplain forests have been preserved. At present, drying out and a lack of hydrodynamics pose the greatest challenges for the conservation of the floodplain landscape. Restoring typical floodplain hydrological conditions and habitats can sustainably safeguard biodiversity and numerous ecosystem services in the medium term. To this end, the Lebendige Luppe project aim to reactivate typical floodplain hydrodynamics with inundation over large areas, the restoration of old river courses and the conversion of intensively farmed areas into typical floodplain habitats. The Lebendige Luppe project, itself is a joint project of cities of Leipzig and Schkeuditz and the NABU Saxony as implementation partner and the University of Leipzig and the UFZ-Helmholtz Centre (Partner for accompanying natural and social science) (Scholz et al. 2022).The implemented and planned restoration measures are accompanied by long-term scientific monitoring (UFZ and Leipzig University). For this purpose, 60 permanent observation plots were set up in the area of the measures according to the BACI design (Before-After / Control-Impact), on which the diversity of selected indicator groups (vegetation, molluscs, ground beetles) as well as groundwater dynamics, water and material balance in the soil, carbon storage and forest growth are recorded (Scholz et al. 2022). By integrating further landscape ecology and nature conservation data, a comprehensive analysis of the status quo and the changes in site conditions, biodiversity and ecosystem functions of the floodplain resulting from the expected floodplain dynamisation is possible, which goes beyond what has been available to date. The resulting simulation of hardwood forest responses to the changing abiotic environmental variables are already the basis for assessing the impact of the planned measures in the implementation process.This data publication contains the tree inventory data of the scientific accompanying research of the winters 2013/2014 and 2016/2017 (first inventory) and a repeat inventory from the winter of 2020/21. The Leipzig riparian forest distributed on old hardwood riparian forest (main tree population older than 90 years) of the forestry office of the city of Leipzig and Sachsenforst as state forest (Scholz et al. 2022). All stands were identified as Riparian mixed forests of Quercus robur, Ulmus laevis and Ulmus minor, Fraxinus excelsior or Fraxinus angustifolia, along the great rivers (Ulmenion minoris) – Annex I habitat type (code 91F0).
description: Two tree inventories of trees with a breast hight diameter of &gt;5cm were conducted on 60 plots (each 2500m²) of the project Lebendige Luppe. The first inventory was conducted in the winters of 2013/14 and 2016/17, the second inventory was conducted in the winter of 2020/21.

title: UWBRAD 500-2000 MHz brightness temperature measurements during the ISSIUMAX campaign in Terra Nova Bay, Antarctica

description: The dataset contains 500-2000 MHz brightness temperature measurements gathered by the Ultra-Wideband Software Defined Microwave Radiometer (UWBRAD) during the Ice Sheet and Sea Ice Airborne Microwave eXperiment (ISSIUMAX) in Terra Nova Bay, Antarctica. UWBRAD was operated from a DHC-6 Twin Otter during the XXXVIII Italian Antarctic Expedition. The campaign collected the first ultrawideband brightness temperature measurements in Antarctica over different targets including sea ice, ice sheets, glaciers, ice shelves, and land. The dataset was collected on 24-25 November 2018 in the coastal region surrounding Mario Zucchelli Station (-74.694807°, 164.113268°). The UWBRAD microwave radiometer measures nadiral circularly polarized brightness temperatures over the entire 500–2000 MHz range using multiple frequency channels. Since this frequency range is not a protected portion of the spectrum, the measurements can be affected by anthropogenic RFI. To address this issue, UWBRAD includes RFI detection and filtering methods to filter out artificial signals received by the radiometer. A full description of the instrument can be found in Andrews et al, 2022 (DOI: 10.1109/TGRS.2021.3090945). The published dataset is in ascii format and consists of geolocated nadiral brightness temperature measurements collected over 12 sub-bands whose central frequencies are 560, 660, 820, 900, 1180, 1240, 1370, 1500, 1630, 1740, 1860, and 1950 MHz. Only measurements with a viewing angle within 5 deg with respect to nadir are reported.

title: Tsambagarav 2009 ice core (Mongolia, 4130 m asl) refractory black carbon record over the past 6,700 years

description: In June 2009, a 72-m long surface-to-bedrock ice core was drilled on Khukh Nuru Uul, a glacier in the Tsambagarav mountain range of the Mongolian Altai (4130 m asl, 48° 39.338' N, 90° 50.826' E). The small ice cap has low ice temperatures and flat bedrock topography at the drill site. This indicates minimal lateral glacier flow and thereby preserved climate signals. The upper two-thirds of the ice core contain 200 years of climate information with annual resolution, whereas the lower third is subject to strong thinning of the annual layers. Here we provide a continuous high resolution (median 2.1 cm per sample) record of concentrations of refractory black carbon (rBC) from the Tsambagarav ice core encompassing the period from 6.7 ka BP to 2008 CE. We analyzed rBC over the entire core (in 2452 discrete samples) with a Single Particle Soot Photometer (SP2, Droplet Measurement Technologies) and a jet (APEX-Q, Elemental Scientific Inc.) nebulizer to aerosolize the aqueous samples using methods described in detail by Sigl et al., (2018) and Osmont et al., (2019). The depth-age model is described in Herren et al., (2013). This dataset underpins and supports analyses of anthropogenic and natural emissions of aerosol species form forest fires, biomass burning and industrial emissions over the industrial (Bauer et al., 2020; Eckhardt et al., 2023) and over pre-industrial periods (Brugger et al., 2018).

title: Harmonized in-situ observations of surface energy fluxes and environmental drivers at 64 Arctic vegetation and glacier sites - Metadata

description: Despite the importance of surface energy budgets (SEBs) for land-climate interactions in the Arctic, uncertainties in their prediction persist. In situ observational data of SEB components - useful for research and model validation - are collected at relatively few sites across the terrestrial Arctic, and not all available datasets are readily interoperable. Furthermore, the terrestrial Arctic consists of a diversity of vegetation types, which are generally not well represented in land surface schemes of current Earth system models.This dataset contains metadata information about surface energy budget components measured at 64 tundra and glacier sites &gt;60° N across the Arctic. This information was taken from the open-access repositories FLUXNET, Ameriflux, AON, GC-Net and PROMICE. The contained datasets are associated with the publication vegetation type as an important predictor of the Arctic Summer Land Surface Energy Budget by Oehri et al. 2022, and intended to support research of surface energy budgets and their relationship with environmental conditions, in particular vegetation characteristics across the terrestrial Arctic.

title: Rock glaciers in the French Alps - inventory of diplacement rates and orthoimages of destabilized landforms in the period 1945 - 2018

description: The present dataset is the basis for the article from Marcer et al. (in review) "Rock glaciers throughout the French Alps accelerated and destabilised since 1990 as air temperatures increased". The dataset describes displacement rates and destabilisation for all the rock glaciers in the region of the French Alps during the years 1945-2018. The methodology used is manual feature tracking of moving boulders on rock glaciers surfaces observed on time lapsed orthoimagery. Most of the orthoimagery we used is already made freely accessible by the the French National Institute of Geography (IGN) through the online portal www.geoportail.com. We computed additional orthoimages on landforms of particular interest, i.e. presenting destabilisation evidence. In this dataset we provide raw feature tracking observations, measured displacement rates and additional orthoimages we computed. All geodata are readable on a GIS software and referenced in EPSG:2154. Other data are provided as CSV spreadsheets.
