ECMWF

• Find the right service — Find which of ECMWF's services holds the data for a question, and get the exact tool names to call next. Returns a ranked list with the reason for each position, whether the service covers the place in the question, and the outside authority to name when the answer isn't ECMWF's to give. The services here hold data on: forecast chart, climate projections, meteogram, Climate DT, ensemble, Extremes DT, how certain is the forecast, MARS request. Use it when a question is about one of those subjects
• List services — List ECMWF's MCP data services and relevant outside authorities, with what each one holds, whether its output is an official product or model guidance, the area it covers and how many tools it offers. Takes no arguments.
• ECMWF charts: Find a forecast chart — [ECMWF charts] Search the catalogue of official forecast charts by what a chart shows, for example 'mean sea level pressure', 'rain', '2 m temperature' or 'wave height'. Returns the product name to pass to get_chart, what each chart shows, and the inputs it takes: the areas it can be drawn on, how far ahead it runs, and the model runs on offer. It also lists the map layers get_map can draw. Start here when you don't already know the product name. It returns a catalogue, not an image.
• ECMWF charts: Get a forecast chart — [ECMWF charts] One official forecast chart as an image, the same chart as on the charts website: pressure, wind, temperature, rain, cloud, waves and the rest of the catalogue. Takes a product name from find_charts, a step in hours ahead or a valid time, and an area such as europe or global; the model run is the latest that has the step unless you name one. Returns the picture with its base time, valid time, area, the page it came from and its licence. The areas are the ones the product publishes
• ECMWF charts: Get an ensemble meteogram for a place — [ECMWF charts] The official ensemble meteogram for one place: how the 51-member ensemble forecast spreads over the next 10 or 15 days for cloud, rain, wind and temperature, drawn as one image. Takes a latitude and longitude anywhere in the world and a place name to label it. Kinds: 10-day, 15-day, 15-day-with-climate, plume, wave. Use it for how confident a forecast for a place is, and how the weather there changes day by day. It answers with a picture of the ensemble, not with numbers, and it i
• ECMWF charts: Get a forecast map for an area — [ECMWF charts] A forecast map for a bounding box you choose, drawn by the Web Map Service: mean sea level pressure, 500 hPa geopotential, 850 hPa temperature and wind speed, and the ensemble mean and spread of each. Takes west, south, east and north in degrees and either a valid time or a step in hours ahead, and returns the map with a background, coastlines and borders, and the legend where the layer has one. Layers: msl_mean_public, msl_public, msl_spread_public, t850_mean_public, t850_public,
• Destination Earth data catalogue: List datasets — [Destination Earth data catalogue] List the datasets available in the catalogue (id, title, description, family, tags).
• Destination Earth data catalogue: Describe dataset — [Destination Earth data catalogue] Describe one dataset: its dataset-specific navigation guidance (follow it), the axis order, and the base selection that identifies it. Call this before navigating a dataset.
• Destination Earth data catalogue: Get axes — [Destination Earth data catalogue] Return the axes (MARS keys) of a dataset for the CURRENT selection branch. For every axis: label, description, selected values, the number of valid options given the other selections, and either the labelled `options` (selectable axes) or a `summary` with the min..max extent (large axes, e.g. dates: choose a range inside it). `invalid` lists selected values that are not available with the rest of the selection, and
• Destination Earth data catalogue: Probe availability — [Destination Earth data catalogue] Read-only "what if" check. Each query is {"axis": "param", "under": {"stream": ["clmn"]}, "target": "133"}: it reports whether `target` is a valid option of `axis` if the `under` values replaced the current `selection` (axes after them are cleared), and how many options that axis would have. Probe both sides of a branching choice before committing to it.
• Destination Earth data catalogue: Build mars requests — [Destination Earth data catalogue] Turn a selection into the minimal list of valid MARS requests, plus the DestinE data locations (Polytope endpoints) that can serve them. Single-valued axes are filled in automatically; check `unset_axes` (axes you left open, which the request then spans entirely).
• Destination Earth data catalogue: Destine authentication help — [Destination Earth data catalogue] How to obtain DestinE credentials and pass them to this MCP server.
• Destination Earth data catalogue: Retrieve data — [Destination Earth data catalogue] Retrieve the data for a selection from DestinE Polytope. The server rebuilds the MARS requests from the selection and fetches each field from one data location that serves it (data split across locations is fetched from each; replicated data only once), or only from `location` if given. It runs the retrieval and returns one download URL per request, reusable until it expires (GRIB, or CoverageJSON when the reques
