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

CO2-flux measurements above the Baltic Sea at two heights: flux gradients in the surface layer?
Summary: The paper presents long-term measurements of turbulent fluxes at the research platform FINO2 in the Baltic Sea. The platform was equipped at two heights (6.8 and 13.8m) for the observation of wind, temperature, humidity and CO2 over a time period of 1.5 years. The paper shows the measured quantities as well as the turbulent fluxes, latent and sensible heat, momentum and CO2 flux. In contrast to the constant-flux layer approach, we found differences in the CO2 fluxes between 6.8 and 13.8m.

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.

A global satellite-assisted precipitation climatology
Summary: We derive a new global 0.05 degree precipitation climatology using satellite data, topography and climate normals via moving window regression. The resulting global 0.05° monthly precipitation climatology, the Climate Hazards Group’s Precipitation Climatology version 1 (CHPclim v.1.0, http://dx.doi.org/10.15780/G2159X), is shown to compare favorably with similar global climatology products, especially in areas with complex terrain and low station densities.

The IPY 2007–2008 data legacy – creating open data from IPY publications
Summary: The International Polar Year 2007-2008 was a synchronized effort of over 60 nations to simultaneously collect data from polar regions. However, large parts of IPY knowledge have only been reported in publications. A concerted effort of PANGAEA (www.pangaea.de) and the International Council for Scientific and Technical Information resulted in the extraction of 1270 data sets from 450 IPY publications. They are now available to the public by open access (http://dx.doi.org/10.1594/PANGAEA.150150).

Woodland Survey of Great Britain 1971–2001
Summary: The Woodland Survey of Great Britain is a unique data set, consisting of a detailed range of ecological measurements at a national scale, covering a time span of 30 years. A set of 103 semi-natural woods spread across Britain were first surveyed in 1971, which were again surveyed in 2000-2003. Standardised methods of describing the trees, shrubs, ground flora, soils and general habitats present were used for both sets of surveys.

Perceived temperature in the course of climate change: an analysis of global heat index from 1979 to 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 to 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.

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 at 153 FLUXNET stations. The final product consists of uninterrupted meteorological records that can be used for running most ecosystem models.

A metadata template for ocean acidification data
Summary: With the rapid expansion of studies on biological responses of organisms to OA, the lack of a common metadata template to document the resulting data poses a significant hindrance to effective OA data management efforts. In this paper, we present a metadata template that can be applied to a broad spectrum of OA studies, including those studying the biological responses of organisms to OA. This paper defines best practices for documenting ocean acidification (OA) data.
