Fetch, open, and summarize SST

Open the executed notebook to inspect four CoastWatch ocean grid centers, their units and provenance, a small spatial plot, and cache reuse. See examples setup to run it interactively or refresh its outputs.

Requires usdata v0.6 or newer. The sample is at 2024-05-06T12:00Z. Its mean is an unweighted average of four nearby grid centers, not a regional climate statistic. ERDDAP's units row becomes metadata rather than an observation; raw bytes and provenance remain intact when the DataFrame is edited.

Saved results include execution and retrieval times plus checksums; NOAA can revise the underlying data. The reader reference explains opening options and the limits of in-memory metadata.
