The GloFAS Reporting Point layer consists of a queryable map, with pop-out windows providing additional information.
The figure below explains the Reporting Points map layer. The definition of the reporting points is described in CEMS-Flood diagnostic and web reporting points.
Reporting points are defined according to the most severe flood signal in the 30-day forecast horizon, using three severity levels (yellow = 2-year, red = 5-yar and purple = 20-year). The following rules are used:
Flood intensity (colour) according to the probability of exceedance of the three flood thresholds. The reporting point marker colours (from light yellow to dark purple) are consistent with the 'Flood Summary for days 1-30' map, showing the same main colours (yellow, red or purple), without the sub-categories of the probability of exceedance information. The following colours and flood category cases are displayed for the reporting points:
Flood tendency (shape) according to the evolution of flood intensity signal over the forecast horizon:
Flood peak timing (border and greyed colours) according to the forecasting timing of the peak flood:
Flood probability (numbers):
Additional information associated with the reporting point layer is available from the map viewer as pop-up plots. These plots display information such as:
Point geographical information: e.g. station coordinates and the equivalent coordinates on the GloFAS river network, country, basin, river, station names or the catchment area.
Forecast summary: e.g. forecast issue date, probability values, tendency and time to peak.
Flood hydrograph: time evolution of the ensemble forecast river discharge
Summary diagrams of catchment meteorological forcing: precipitation, snowmelt and temperature.
Consistency diagrams: show the evolution of the forecast signal over forecast run time. They display the forecast threshold exceedance for each return period threshold (2-, 5-, 20-year) for each day of the forecast horizon for the latest seven consecutive forecast runs.
