The epsgram displays an automatically generated forecast meteorological parameters, from the A-LAEF ensemble system. It is generated with a time step of one hour and is updated twice a day. The solid line represents the median of the forecast parameter. 50% of the scenarios lay between the lower and upper quartiles (25th and 75th percentiles), which represent forecast uncertainty, displayed as the area of the chart filled with darker colour. Edges of the area filled with lighter colour denote the maximum and minimum values of the ensemble. These represent the least likely, although still possible extremes.

The epsgram originating from the A-LAEF system is combined with the meteogram from the deterministic ALADIN/SHMU model, displayed as a dashed line in **magenta**. The ensemble median and the value forecast by the deterministic ALADIN/SHMU model are displayed above the top right corner of each chart, when the cursor is hovered above the charts at positions representing each hour.

Each epsgram is generated for a point defined by geographic coordinates. The forecast values are representative of a surrounding area of about 5 ⨯ 5 km and elevation as per model topography, which may not correspond with the location's actual elevation.

The EPSGRAM displays an automatically generated forecast meteorological parameters, from the ECMWF ensemble system. It is generated with a time step of three hours (for the first days) or of six hours (days 7-10) and is updated twice a day. The solid line represents the median of the forecast parameter. 50% of the scenarios lay between the lower and upper quartiles (25th and 75th percentiles), which represent forecast uncertainty, displayed as the area of the chart filled with darker colour. Edges of the area filled with lighter colour denote the maximum and minimum values of the ensemble. These represent the least likely, although still possible extremes.

The ensemble median, minimum and maximum for every 3 or 6 hours are displayed above the top right corner of each chart, when the cursor is hovered above the charts.

Each epsgram is generated for a point defined by geographic coordinates. The forecast values are representative of a surrounding area of about 9 ⨯ 9 km and elevation as per model topography, which may not correspond with the location's actual elevation.
