CW Data Portal
Global, high-resolution, and ensemble model data — designed for fast browsing, clean charts, and practical forecasting.
Explore a collection of weather model data including NOAA GFS and ECMWF, plus GEM and ARPEGE for additional perspective. For higher-resolution detail, AROME, ARPEGE, UKMET UKV and ICON-EU provide short-range guidance across Europe.
Ensemble suites (e.g., GEFS) add confidence signals, with additional tools for storm risk, radar, pressure charts and long-range output.
This data portal is a joint venture between CW Weather and realweather.co.uk, combining technical infrastructure, data processing, and forecasting expertise.
Models & Tools
Quick links to your most-used datasets.
Interactive Model Map Multi-Model
Compare outputs from major global and regional models in one interactive map interface with zoom and layer controls.
NOAA GFS Global
Global forecast model for synoptic patterns, pressure, wind, and temps with a strong ecosystem of verification.
GFS AI AI / Global
AI-enhanced version of the GFS model offering rapid-processing guidance and additional comparison alongside the operational run.
ECMWF FAST Global
ECMWF FAST model for medium range guidance in 24 hour steps. Useful for pattern changes, blocking and storm evolution.
ECMWF IFS Global
High-skill global model for medium range guidance in 6 hour steps, with more variables. Useful for pattern changes, blocking and storm evolution.
ECMWF AI Global
AI-enhanced forecasting outputs for rapid guidance and comparison with physics-based runs.
ECMWF HRES (9km) Global
ECMF HRES global model providing high-quality medium-range forecasting and strong performance in dynamic weather setups.
CMC GEM Global
Additional global perspective for trend confidence and scenario comparison alongside GFS and ECMWF.
UKMET Global Global
Met Office global model providing high-quality medium-range forecasting and strong performance in dynamic weather setups.
ARPEGE Europe
Good regional detail for Europe, often useful for wind, frontal timing, and precipitation structure.
ICON-EU Europe
High-resolution European guidance for precipitation, convective detail, and mesoscale features.
UKV UK
Short-range UK detail for local impacts: wind, rain bands, showers, and near-term temperature gradients.
AROME Hi-res
Very high resolution, great for near-term precipitation intensity, shower structure, and short-lived features.
HARMONIE Hi-res
Very high resolution, great for near-term precipitation intensity, shower structure, and short-lived features.
RWx Pro 3km Hi-res
In house high resolution data using the GFS as a base, great for near-term precipitation intensity, shower structure, and short-lived features.
RWx Pro 10km Hi-res
In house high resolution data using the GFS as a base, good regional detail for the UK, often useful for wind, frontal timing, and precipitation structure.
GEFS Ensemble Ensemble
Scenario spread and confidence signals. Useful for storm track uncertainty and pattern reliability.
CFSv2 Weekly Data Ensemble
Scenario spread and confidence signals. Useful for longer term trends.
Radar / Observations Live
Live observations and radar products for “what’s happening now” verification and short-term decision making.
