→ Data access: Social Media Activity layers are publicly available. The remaining layers under this category are available in real time exclusively to the EFAS partnerpartners, and become publicly available for any date older than the embargo period.

Data access:  Products that are based on seasonal forecasts are open for the general public. The remaining layers under this category are available in real time exclusively to the EFAS partners and they become publicly available for any date older than the embargo period.

Initial condition layers

Within the EFAS-IS, one can find information of the initial hydrological and meteorological conditions which are estimated directly from either observations or the hydrological model or satellite data (see Figure 7). More information about the initial conditions can be foundhere.Data access: 

The Initial Conditions menu with the available layers.

→ Data access: The layers under this category are publicly available.

Flash flood layers

EFAS is also providing information on flash floods. This can be found in the Flash Flood menu and particularly after selecting the ERIC reporting points layer.

...

For the ERIC reporting points, the number placed near the triangle indicates the % of COSMO-LEPS members (20 in total) exceeding the 5-year return period threshold. The triangles can have different colour and size depending on the (probability of the) threshold exceedance and lead time. More information on the ERIC points is available here. Information about the scientific evaluation of the ERIC product can be found here.

Data access:  The layers of 24-h precipitation accumulation (TAMIR and ERICHA) are open for the general public.The remaining layers under this category are available in real time exclusively to the EFAS partners and they become publicly available for any date older than the embargo period.

Static layers

The static layers menue contains mostly auxiliary layers easing vizualisation and interpretation of the information presented in the EFAS IS. For example, the LISFLOOD drainage network and the Catchments layer presented together with the Major Rivers layer allow for a better orientation on the map.

Evaluation layers

EFAS provides to the users information on the historical model performance presented at the catchment scale or at the stations that hydrological data are available. 

...

The hydrological forecast skill (in terms of the CRPSS) presented at the locations that hydrological data are available.

→ Data access: The layers under this category are publicly available.

Meteorological layers

Similar as for the Hydrological layers, the Meteorological layers menu provides information on the forecasted precipitation for each single forecast (two deterministic and two probabilistic) accumulated over the whole forecast range for a specific type of forecast. Deterministic forecasts are presented as absolute values whereas the probabilistic ones are visualised with percentages.

Precipitation animations

In addition to the accumulated precipitation amounts presented under the Meteorological layers menu (see above), the precipitation amounts for the two probabilistic forecasts (COSMO and ECMWF) can be visualised as precipitation animations as well. The animation is opened in a pop-up window.
