This network includes ground-based measurements for approximately 50 stations in the Renewable Resource Monitoring and Mapping (RRMM) Solar Radiation Monitoring Network. The current stations provide one-minute resolution data for three solar components, along with temperature, humidity, wind speed and direction, and barometric pressure. The network began with three stations in January 2013, and additional stations were added in May and June of that year. Additional stations of the same design are being added, and a group of higher tier research quality stations will be added in the second half of 2013 and in early 2014. Solar data is collected at various temporal resolutions: 1-minute, hourly, daily, monthly, and annual averages of 3-second samples for all solar and meteorological components are collected at each station. IRENA has access to monthly data only. Other resolutions are available for purchase directly from K.A.CARE.

Satellite images are routinely processed to yield information on clouds properties. The Copernicus Atmosphere Monitoring Service (CAMS) offer access to properties of the cloudless atmosphere every 3h. These sets of information are combined together with site-specific properties, e.g. elevation and shadowing by local relief, to produce estimates of the solar radiation at a given site. Thus, the computation is made on an ad hoc basis on-the-fly. To better account for changes in solar position and possible shadowing effects, computations of the solar radiation are made every 1 min and the results are then aggregated e.g. every 15 min or 1 h, chosen by the user. The operations that are currently working satisfactorily though improvements should be brought to ease access to data by users. A new use case has arisen recently due to the large penetration of PV plants in Europe. Grid operators need a better knowledge of the very local production of electricity by PV plants that are connected to the grid in order to ensure the stability and quality of the electricity delivered to customers. Accordingly, their requests are for time-series of solar radiation over a regular grid of points covering their area of interest which may be nation-wide. Though the time-series may be short, e.g. two days of estimates every 15 min, the number of grid nodes may be high. An area of say 1000 km x 1000 km with a grid cell of 10 km in size means running the model for 10 000 nodes at the same time. The concept of cloud computing supporting the NexGEOSS infrastructure may help in solving this issue in both computational aspects and dissemination aspects.
