Environmental — Data Braids

Weather and seismic data for environmental science, agriculture, and multi-hazard analysis. Public domain datasets from US federal agencies.

NOAA GHCND

Global Historical Climatology Network daily weather observations. 100K+ stations worldwide. Daily temperature (min/max/avg), precipitation, snowfall, and snow depth records spanning the 1700s to present.

What’s Possible

• Correlate weather patterns with agricultural yields (USDA NASS)
• Feed airSpring atmospheric models with historical climate data
• Combine with USGS seismic data for multi-hazard environmental analysis
• Ground truth for precision agriculture yield prediction (groundSpring)

USGS earthquake catalog (monthly)

Monthly earthquake catalog from the USGS FDSN web service. Magnitude, location (lat/lon/depth), and focal mechanism for global seismic events.

What’s Possible

• Seismic pattern analysis for groundSpring
• Combine with NOAA GHCND weather for multi-hazard correlation studies
• Feed environmental risk models with real-time seismic data
