Short summary
New estimates of population and land area by settlement types within Low Elevation Coastal Zones (LECZs) based on 4 sources of population data, 4 sources of settlement data, and 4 sources of elevation data for the years 1990, 2000, and 2015. The paper describes the sensitivity of these estimates and discusses the fitness of use which could guide user decisions. Data choices impact the number of people estimated within LECZs, but across all sources the LECZs are predominantly Urban and growing.Hide

Short summary
Large portions of the Earth's surface are expected to experience changes in climatic conditions. The rearrangement of climate distributions can lead to serious impacts on ecological and social systems. Major climate zones are distributed in a predictable pattern and are largely defined following the Köppen climate classification. This creates an urgent need to compile a series of Köppen climate classification maps with finer spatial and temporal resolutions andimproved accuracy.

Short summary
Long-term urban extent data are highly desirable for understanding urban land use patterns and achieving sustainable development goals. Cities in late imperial China generally had city walls, and these walls were usually built around the urban built-up area. By restoring the scope of the city wall, the urban extend in this period could be restored. In this study, we generated China Urban Extent Dataset in the 15th–19th centuries in six representative years based on multiple historical documents.Hide

Climate change strongly impacts the Arctic region with a clear sign of higher air temperature and more precipitation. A sustainable observation program has been carried out in Lake Orajärvi in Sodankylä, Finnish Lapland. The high-quality air-snow-ice-water temperature profiles are measured every winter since 2009. The data can be used to investigate the lake ice surface heat balance and the role of snow on lake ice mass balance, parameterization of snow to ice transformation in snow/ice models.Hide

Short summary
Global mean sea level change observed from 1993 to 2016 (at a mean rate of 3.05 mm per year) matches the combined effect of changes in water density (thermal expansion) and ocean mass. Ocean mass change is assessed through the contributions from glaciers, ice sheets and land water storage or directly from satellite data since 2003. Our budget assessments of linear trends and monthly anomalies utilise new datasets and uncertainty characterisations developed within ESA's Climate Change Initiative.Hide

Satellites provide a global overview of Earth's ecosystems, but they have coarse resolutions and low revisit times. Small scale vegetation patterns and sudden shifts in plant growth can therefore be missed. In this paper, we show how to fill these gaps with vegetation indices obtained with ordinary time-lapse cameras – deployed across a valley on Svalbard. We show how to adjust for unwanted camera movement, and that vegetation indices from ordinary cameras compare well to thosefrom satellites.

The Boundary Layer (BL) is well understood when convectively mixed, yet we lack this understanding when it turns stable and no longer follows classic similarity theories. The NYTEFOX campaign collected a unique meteorological data set in the Arctic BL of Svalbard during polar night, where it tends to be highly stable. Using innovative Fiber-Optic Distributed Sensing we are able to provide unique insight into atmospheric motions across large distances resolved continuouslyin space and time.

We established an open-access, integrated, marine data collection from 1996 to 2015 in the German Bight as a database for scientific, economic, and governmental interest. This paper presents data products from model simulations for tidal elevation, current velocity, bottom shear stress, salinity, wave parameters, and -spectra at a high temporal and spatial resolution. Model results are processed to meaningful parameters (i.e. tidal characteristic values, e.g. tidal range) for accessibility.Hide

Short summary
A catalog of point sources of Nitrogen oxides was created using satellite observations of NO2. Key for the identification of point sources was the divergence, i.e. the difference between upwind and downwind levels of NO2. The catalog lists 451 locations, of which 242 could be automatically matched to power plants. Other point sources are metal smelters, cement plants, or industrial areas. The catalog thus allows checking and improving of existing emission inventories.Hide

Revised manuscript accepted for ESSD (discussion: closed, 4 comments)Short summary
Short summary
Semi-arid regions depend on the freshwater resources from the rainy seasons as they are crucial for ensuring security for drinking water, food, and electricity. Thus, forecasting the conditions for the next season is crucial for pro-active water management. We hence present a seasonal forecast product for four semi-arid domains in Iran, Brazil, Sudan/Ethiopia, and Ecuador/Peru. It provides a benchmark for seasonal forecasts and, finally, a crucial contribution for improved disasterpreparedness.

Revised manuscript has not been submitted (discussion: closed, 3 comments) Short summaryShort summary
Accurate estimates of englacial temperature and geothermal heat flux are incredibly important for constraining model simulations of ice dynamics (e.g. viscosity is temperature-dependent) and sliding. However, we currently have few direct measurements of vertical temperature (i.e. only at boreholes/ice domes) and geothermal heat flux in Antarctica. This method derives attenuation rates, that can then be mapped directly to englacial temperatures and geothermal heatflux.

The retreat of glaciers over the QTP is intensifying. To understand changes in glaciers, the two inventories (RGI 4.0 and GIC-Ⅱ) provide potential, but glacier volumes are not convincing. The study recalculated and compared glacier volumes in RGI 4.0 and GIC-Ⅱ for the QTP. The results indicate the slope-dependent algorithm performs better than area-volume-based equations. The northern QTP has a larger degree of fragmentation. An obvious offset of glacier volumes in different aspects is observed.Hide

Short summary
The Emissions Database for Global Atmospheric Research supports climate policy making with a global dataset at disaggregated country & source-sector level for 1970–2012. This dataset is not only unique in its space/time coverage, but also in its completeness & consistency of CO2, CH4 & N2O emissions compilation for all anthropogenic activities except land use. Comparison with UNFCCC values show that estimates are within the uncertainty range, but have an annual variation smaller than this range.Hide

Preprint withdrawn (discussion: closed, 8 comments) Short summaryShort summary
The research, conducted in Manitoba, Canada, involved the development of datasets for hydrological modelling applications. The datasets included weather, hydrometric and water chemistry variables required to run models at an hourly time-step and assess their predictive performance for stream flow and water quality. The data and methods developed will be useful for other hydrological assessments and modelling studies in this region and in similar landscapes and climates around the world.Hide

Short summary
Using the best-available open access data from GBIF, and a compilation of over a hundred high resolution global GIS layers that incorporated variables such as biological, climatic, and socio-economic predictors, we built the first generalizable model ever obtained using 104 predictors on a 1 km scale, predicting the potential ecological niche of Peregrine Falcons (_Falco peregrinus_) around the world. The GIS layers can be found at https://scholarworks.alaska.edu/handle/11122/7151.Hide

Preprint withdrawn (discussion: closed, 2 comments) Short summaryShort summary
Weather data in mountainous rain-to-snow transition zones are limited, but vital for water resources. We present a 10-year dataset for this zone that includes hourly temperatures, relative humidity, stream flow, snow depth, precipitation, wind speed/direction, solar energy, and soil moisture at 11 stations. Average air temperatures are near freezing eight months each year, so that slight warming may determine whether rain falls instead of snow, affecting water supplies, ecosystems and fire risk.Hide

This study produced a high-resolution dynamical downscaling data set for the Alaskan North Slope and surrounding areas. It helps to resolve the problem of the sparse observation over this region, where routinely and accurately measuring climatic variables is extremely difficult. This data set boosts up multiple research projects that explore the various climatic impacts over the Alaskan North Slope of the past and the future.Hide

Preprint withdrawn (discussion: closed, 6 comments) Short summaryShort summary
The Eddy-covariance measurements from global network of flux sites help understand the emergent ecosystem properties. This study presents an approach to assess the representativeness of the observations at the flux sites and upscale the measured fluxes to develop time series of high resolution global gridded data set. Upscaled gross primary productivity data sets captures the heterogeneity of terrestrial ecosystem and reflects the seasonal and interannual variability observed at flux sites.Hide

Short summary
This paper is written as a part of our project in analyzing groundwater system in Semarang (Indonesia) area based on the water quality. Semarang is highly dense populated, serves as the capital of Mid Java Province. The aquifer in this area is a combination between volcanic and alluvium system. All data has been clarified and validate on-field. We applied free statistical package for later analysis. The code is given in this paper. Hopefully we can gain constructive comments to improve our work.Hide
