PyRe WeatherPublication quality weather maps in seconds
A climate reanalysis playground for students and researchers.
PyRe Weather helps meteorology students, teachers and researchers build custom atmospheric maps from any date since January 1st, 1950.
What you can do
Every item opens a live example in the builder.
- 3-hourly maps at all eight analysis times: the 1993 Storm of the Century at its peak
- Daily composites over ranges or custom date lists: four days of the deadly 1995 Chicago heat wave
- Monthly and seasonal composites: the 1997-98 El Niño winter, three months in one map
- Anomaly maps against 30-year climatology: the failed Indian monsoon of July 2002
- Climatology views for any calendar month: September moisture across hurricane alley
- Wind overlays, contours, and pressure center detection
- Fixed scientific color scales with provenance-labeled output
- Every map is a shareable link, so a whole class can open the same analysis

No account? You can still build maps and save the images to your computer, but they disappear as soon as you navigate away from the builder.

Help keep PyRe online
PyRe is free to use, but the data, compute and hosting behind every map are not. If PyRe saves you time, a donation of any size keeps the maps coming.
