Processing of water level derived from water pressure data at the Time Series Station Spiekeroog
Summary: We present water level data derived from long term measurements of water pressure at the Time Series Station Spiekeroog (southern North Sea). Problems addressed during data processing include outliers, data gaps and sensor drift. For quality control, we compared the processed data to measurements of water level obtained nearby. We also carried out a storm flood analysis and a Fourier analysis to identify major tidal components.

Perceived temperature in the course of climate change: an analysis of global heat index from 1979–2013
Summary: We evaluate global changes to heat index, a measure of perceived temperature. The product is daily means, minima and maxima gridded to 0.75°x0.75° for the entire globe from 1979-2013. The results show the uneven distribution in changes in heat index throughout space and time. They can serve as a basis for future studies on the evolution of heat index in climate change and its effects on human society.

The Global Terrestrial Network for Permafrost Database: metadata statistics and prospective analysis on future permafrost temperature and active layer depth monitoring site distribution
Summary: The authors introduce the new database of the Global Terrestrial Network for Permafrost (GTN-P) on permafrost temperature and active layer thickness data. They describe the operability of the Data Management System and the data quality. By applying statistics on GTN-P metadata, they analyse the spatial sample representation of permafrost monitoring sites. Comparison with environmental variables and climate projection data enable identification of potential future research locations.

Woodland survey of Great Britain 1971–2001
Summary: The Woodland Survey of Great Britain is a unique dataset, consisting of a detailed range of ecological measurements at a national scale, covering a time span of 30 years. A set of 103 woods spread across Britain were first surveyed in 1971, which were again surveyed in 2001-3. Standardised methods of describing the trees, shrubs, ground flora, soils and general habitats present were used for both sets of surveys.

CoastColour Round Robin datasets: a database to evaluate the performance of algorithms for the retrieval of water quality parameters in coastal waters
Summary: The CoastColour project Round Robin project funded by the European Space Agency was designed to set up the first database for remote sensing algorithms testing and accuracy assessment of water quality parameters retrieval in coastal waters, from satellite imagery. The database includes in situ bio-geochemical and optical measurements in various water types at 17 sites, match-up reflectance products from the MEdium Resolution Imaging Spectrometer (MERIS), and radiative transfer simulations.

Filling the gaps in meteorological continuous data measured at FLUXNET sites with ERA-interim reanalysis
Summary: In order to fill the gaps in the in-situ meteorological data that is acquired at FLUXNET stations, we develop a method that makes use of the reanalysis ERA-interim, which is available globally and at a high temporal resolution. Because the ERA-interim data are not measured at site level, we bias-correct them. The developed method is applied and evaluated on 153 FLUXNET stations. The final product consists of uninterrupted meteorological records that can be used for running most ecosystem models.
