Weather Data

The weather data below is sourced from weather balloons, and publicly available via NOAA’s Integrated Global Radiosonde Archive (IGRA). This data is downloaded and post-processed by the StrewnLAB algorithm, to account for changing weather patterns and weather balloon drift. The plots have altitude on the y-axis, in kilometers above sea level. The wind speed below 10km altitude has large effect on the drift of meteorites.

There was light wind from the SE, peaking at only 15 m/s @ 10 km altitude. This has a small effect on the strewnfield, spreading the lighter fragments toward the NW.
