25 Mar State-of-the-art Methodologies

After joining forces, the Team has developed a new methodology for satellite retrieval of high frequency (15-min ≈ real-time) high spatial resolution (0.05 degree longitude x 0.05 degree latitude) DNI, GHI and DHI solar radiation spectra at the Earth’s surface that include the effects of...

25 Mar The big picture

The 5th assessment report of the Intergovernmental Panel for Climate Change published in 2013 concluded that the evidence for climate change is now incontrovertible and that a large part of this ongoing change is attributable to human activities, particularly the increased release of greenhouse gases...

24 Mar Data dissemination

Due to the inherent importance for solar energy, health and environmental protection industries, it is essential that the NOA team make their results as accessible as possible. They have already achieved some success in this context, contributing regular UV maps and forecasts to Greek weather...

24 Mar The APPlication of information

One of the most exciting applications of solar radiation spectra, in addition to solar energy forecasting, is being able to provide  real-time UV radiation alerts to the general public. In the not-too-distant future, app developers will be able to create mobile applications that pull data...

24 Mar Clouds and aerosols

Alternative models and methodologies for calculating surface radiation have of course existed for several years. While there is considerable heterogeneity in these models, most share a similar limitation especially linked with the accuracy of accounting for the effect of cloud cover and atmospheric aerosols on...

24 Mar The nowcast

By exploiting the full-Earth viewing potential of geostationary satellites, the team have developed a system that delivers regional ‘nowcasts’ of the solar radiation spectrum calculated on a high resolution grid at 15-minute intervals. “We use satellite-derived cloud optical properties and other atmospheric parameters (eg. aerosols...
