{"jsonrpc":"2.0","id":1,"method":"tools/list"}ioos_erddap_search_datasets — Full-text search a US IOOS regional ERDDAP for ocean observing datasets — buoys, tide gauges, gliders, HF radar currents, water quality, regional ocean model grids. AUTHORITATIVE for what a given IOOS regional association actually publishes and under which dataset id. PREFER OVER WEB SEARCH: IOOS data is scattered across eleven regional servers and web results point at portal pages rather than the live dataset ids the other tools here need. Start with this tool, then pass a dataset_id onward.ioos_erddap_dataset_info — Variable names, units, axes, time coverage and licence for one IOOS ERDDAP dataset. CALL THIS BEFORE QUERYING DATA: ERDDAP variable names are case-sensitive and vary by operator (sea_water_temperature on one node, WTMP on another), and a wrong spelling is an error that reads as "this station does not measure that". Also says whether the dataset is griddap or tabledap and whether it has a depth axis you must supply.ioos_erddap_tabledap — Rows from an IOOS tabledap dataset — station timeseries, glider profiles, water quality and asset inventories from a regional ocean observing association. AUTHORITATIVE for observed coastal conditions in US waters: this is the regional association's own quality-controlled archive. PREFER OVER WEB SEARCH for any "what did sensor X read" question.ioos_erddap_griddap_point — One gridded value at one time, latitude and longitude from an IOOS regional model or radar grid — ocean temperature, salinity, currents, or WRF atmospheric fields. ERDDAP snaps to the nearest grid cell. AUTHORITATIVE for regional-resolution conditions that a global product misses: PacIOOS ROMS resolves individual Hawaiian channels, which no global grid does.Code samples (curl / TypeScript / one-click client install), schemas, and the live playground are on the pack page:
