Building on achievements and experience gained through the EU project DAMOCLES and international data management during the International Polar Year, ACCESS, data management was implemented using the same platform as used for DAMOCLES. A metadata-driven approach through which all datasets are properly described with discovery and use metadata was chosen in order to simplify data management and ...

Many aspects of human societies, such as food production, water availability and management, health, energy production and consumption etc., depend critically on climate variability and change. While some countries have the resources and infrastructure necessary to respond to the variability of climate, others are more vulnerable, to the point that large climate anomalies and extremes can cause...

The goal of the WMO Expert Meeting on Agricultural Drought Indices was to move forward in the selection of a single drought index that would be used worldwide in the assessment of agricultural drought and its severity. This chapter discusses the challenges in identifying a single index to accomplish this task. Given the complexities of drought and its diverse sectoral impacts, this is a formida...

An automated Fourier Transform Spectroscopic (FTS) solar observatory was established in Darwin, Australia in August 2005. The laboratory is part of the Total Carbon Column Observing Network, and measures atmospheric column abundances of CO2 and O2 and other gases. Measured CO2 columns were calibrated against integrated aircraft profiles obtained during the TWP-ICE campaign in January– February ...

Abstract A range of oxygenated volatile organic compounds (OVOCs) are present in the atmosphere as a result direct emissions and products atmospheric oxidation. Long-term measurements important to understand changes these emission sources oxidation processes. Accurate stable traceable gaseous primary reference materials needed underpin rigorous quality assurance control at monitoring stations s...
