Add NASA IMERG analysis quickstart notebooks (early + late)#42
Merged
Conversation
Add quickstart notebooks for the NASA GPM IMERG global half-hourly precipitation datasets, one for the Late Run (higher quality, ~12-18 h latency) and one for the Early Run (near-real-time, ~4 h latency). Each notebook opens the public anonymous Icechunk store directly (IMERG is not yet in the STAC catalog; the dynamical_catalog.open comment is left in place for the later catalog swap) and walks through a global precipitation snapshot, a California atmospheric river accumulation, a cross-hemisphere monsoon comparison, the quality-index observation swaths, and an animated atmospheric river. A 400x300 thumbnail is included for each dataset. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01Vz7QJ7V2TA1qoi6TWKNNLk

Adds quickstart notebooks for the two NASA GPM IMERG global half-hourly precipitation datasets:
nasa-imerg-analysis-late.ipynb— IMERG Late Run (higher quality, ~12-18 h latency)nasa-imerg-analysis-early.ipynb— IMERG Early Run (near-real-time, ~4 h latency)Each notebook opens the public, anonymous Icechunk store directly. IMERG is not yet in the STAC catalog, so the
dynamical_catalog.open(...)line is left as a comment for the later catalog swap.Both walk through the same set of examples (which exist in both archives): a global precipitation snapshot, a California atmospheric-river accumulation, a cross-hemisphere monsoon comparison, the quality-index observation swaths, and an animated atmospheric river. Each dataset gets a 400x300 thumbnail (
nasa-imerg-analysis-{early,late}-thumbnail.png).Both notebooks execute cleanly end-to-end via
uv run .internal/run_notebooks.py(0 errors, each < 4 MB) and are committed with executed outputs per the repo convention.🤖 Generated with Claude Code
