Global Surface Archives

Global Surface Archives presents an unparalleled compilation of hourly and special METAR and SYNOP weather observations, plus decoded CSV data. This makes it the most extensive repository of its kind. This collection is a treasure trove for meteorologists, researchers, and weather enthusiasts, offering historical weather data that spans from January 1, 1930, to current (2024 and beyond). The data, stored in plaintext formats like SYNOP, METAR, and CSV, ensures easy accessibility and compatibility with common software tools, allowing for the plotting of historical charts anywhere in the world. Unlike complex binary datasets like the NCEP Reanalysis series, Global Surface Archives prioritizes user-friendliness and versatility. The plaintext format means that anyone can access and analyze the data using standard text editors or viewing software like Digital Atmosphere and MetPy.

Global Upper Archives

Global Upper Archives, presented by Weather Graphics, is the most comprehensive repository of WMO TEMP-formatted upper air weather data available today. This collection is designed for seamless integration with popular meteorological software such as Digital Atmosphere and RAOB, enabling users to effortlessly plot historical upper-air charts and soundings across the globe. The package covers an extensive range covering several decades. Much like Global Surface Archives, this collection avoids the complexity of formats like XML or JSON, opting instead for plaintext ASCII in the universally recognized TEMP format (TTAA/TTBB/PPBB). This choice ensures maximum compatibility and ease of use, allowing the data to be effortlessly incorporated into a wide range of meteorological programs, including Digital Atmosphere, MetPy, and GEMPAK.
