Research forecast experiment produced with ECMWF IFS cycle 47R1, at TCo399 (25km), for the EUREC4A field campaign (15.01.2020-14.02.2020). Initialized from the hfa8 analysis, in which no dropsondes are assimilated, with fields saved on model levels (bit identical to hfa8 forecasts)

Where precipitation is forecast, a type of precipitation can be assigned according to the temperature structure of the model atmosphere that includes the layers through which the model precipitation falls...

This dataset contains atmospheric mixing ratios of carbon dioxide (CO2), methane (CH4) and carbon monoxide (CO), CO2 and CH4 fluxes at the surface, CO2 tagged tracers to monitor the atmospheric enhancement associated with anthropogenic emissions and natural fluxes, and meteorological parameters from very high resolution (9km) global simulations with the Integrated Forecasting System of the European Weather Centre for Medium Range Weather Forecasts (ECMWF).

These diagrams compare scores of ensemble control (red) and ensemble members (central 50% of ...

Total accumulated rainfall charts identify areas at greater risk of significant rainfall (or rain equivalent e.g.snowfall) but give no information regarding whether this occurs over a short or prolonged time period...

This display helps with the recognition of clouds of different layers, even when they overlap. Brighter colouring represents greater cloud cover. Cloud-free areas appear white while areas of full cloud cover at all levels appear dark grey (e.g. active fronts)...

The charts show the forecast value of the vertically integrated total column water (vapour + cloud water + cloud ice but with no precipitation included) in units of kg m⁻²...

This chart shows the anomaly in precipitation (in mm of rainfall or rainfall equivalent) during a 24 hour period immediately prior to the chosen valid date/time...
