MSWX
Multi-Source Weather
Explore how climate zones have shifted over time — and may continue to shift — across the Earth’s land surface.
Overview
Multi-Source Weather (MSWX) is an operational, high-resolution (3‑hourly 0.1°), bias-corrected meteorological product with global coverage from 1979 to 7 months from now.
Other meteorological products, such as ERA5, HydroGFD, PGF, and WFDE5, are not available in near real-time, lack freely available forecasts, and have a coarse spatial resolution (≥0.25°). MSWX combines the best data sources for each time-scale and eliminates systematic biases to provide an effective and readily available solution for use in operational modeling applications.

Example
Air temperature (°C)
Comparison between air temperature forecasts for Europe from MSWX-Long and ECMWF-SEAS5 on March 11, 2021, illustrating the enhanced detail and bias correction provided by MSWX. ECMWF-SEAS5 is generally considered the best seasonal forecasting system currently available. Data represent the first ensemble member of the forecast initialized on February 1, 2021.
