From kilobytes to petabytes for global change research: take the skills survey!

By Vicky Lucas Institute for Environmental Analytics If you deal with megabytes of environmental sample data, or gigabytes of sensor data, or terabytes of model data or petabytes of remote sensing data, then I’d like you to take a survey.  … Continue reading

The value of future observations

By Alison Fowler The atmosphere and oceans are being routinely observed by a myriad of instruments. These instruments are positioned on board orbiting satellites, aircraft and ships, surface weather stations, and even balloons.  The information collected by these instruments can … Continue reading

How can a hurricane near the USA affect the weather in Europe?

By John Methven It may seem bizarre that processes occurring within clouds near the USA, involving tiny ice crystals and water droplets, can have an influence on high-impact weather events thousands of kilometres away in Europe, and our ability to predict them … Continue reading

Where is the high probability?

By Peter Jan van Leeuwen To determine the uncertainty in weather and climate forecasts an ensemble of model runs is used, see Figure 1. Each model run represents a plausible scenario of what the atmosphere or the climate system will do, … Continue reading

Producing quantitative estimates of radiative forcing

By Will Davies Last year the Paris climate conference agreed to an action plan to limit global warming to below 2 degC – preferably 1.5 degC. Various initiatives are measuring performance against this target – such as the global warming … Continue reading

An artefactually introduced monthly cycle in the ensemble fields constrained by HadISST2

By Xiangbo Feng ECMWF has recently developed two major ensemble products for 20th century climate, i.e. ERA-20CM and CERA-20C, within ERA-CLIM and ERA-CLIM2 projects. ERA-20CM is in ECMWF’s public datasets now, and CERA-20C has been scheduled to disseminate in the near … Continue reading

Understanding Summer Flash Flooding

By Adrian Champion ‘Flash flooding’ is flooding that only lasts between a few hours and a day and typically has very little warning. There are many causes of flash flooding, from the meteorological conditions that lead to the rainfall that … Continue reading

The interaction between aerosols and clouds

By Nicolas Bellouin As part of the Copernicus Atmosphere Monitoring Service (CAMS), I lead an activity that will provide in August new estimates of radiative forcing of climate due to changes in atmospheric composition. One of the radiative forcing mechanisms … Continue reading
