Returns a single earthquake in decision-ready form, either by its USGS event identifier or as the most significant event matching a search. Magnitude is reported with the magnitude type, because moment magnitude and local magnitude are not interchangeable at the edges of their ranges. Depth and, whe

Retrieves the earthquakes within a radius and time window of a point and turns them into an exposure figure. Each event contributes according to its magnitude and its distance, using an explicit formula that is returned with the result: energy scales exponentially with magnitude and attenuates with

Clusters earthquakes that are close in space and time into sequences, using a single-link approach with an explicit distance and time threshold that both appear in the result. For each sequence you get the strongest event, the events that preceded it and those that followed, the duration, the spatia

Returns the latest instantaneous values at a USGS streamgage, together with what makes them readable. A stage of three point four feet means nothing on its own, so each value is placed against the station own record for the requested reference period: the minimum, median and maximum, and the percent

Compares the recent record of a gauge against its own longer history and reports three kinds of finding, kept separate because their causes differ. An extreme level is a reading in the top or bottom percentile of the reference period. An unusual rate of rise is a change per hour exceeding the statio

Retrieves water quality results for a monitoring site from the Water Quality Portal and normalises them into a comparable shape. The real work is units: the same measurement appears there as mg/L, ug/L, ppm and mg/l in mixed case, and combining them unchecked puts factor-of-thousand errors into any

Returns the German Weather Service reference-period values for the station nearest a coordinate: monthly means and annual totals for air temperature, precipitation and sunshine duration, plus the mean annual counts of frost days, ice days, summer days and hot days. Which station supplied the values

Turns an hourly forecast into the thing that is actually planned around: continuous frost windows. Each window carries its start and end hour, its duration, the lowest temperature within it and the hour that low occurs, so a two-hour dip at dawn is distinguishable from a night-long freeze. Air frost

Accumulates growing degree days at a location from the hourly forecast, for a base temperature you choose. Two methods are returned side by side: the hourly integration, which is the more accurate, and the conventional average of daily maximum and minimum, which is what agronomic tables and most pub

Computes reference evapotranspiration by the FAO-56 Penman-Monteith method from hourly forecast data, applies a crop coefficient, subtracts effective rainfall and returns the resulting daily water deficit and its running total. The method is named because it matters: a simple temperature-based estim

Calculates the Canadian Fire Weather Index components from an hourly forecast: the Fine Fuel Moisture Code for the surface litter that carries ignition, the Duff Moisture Code and Drought Code for the deeper layers that determine whether a fire keeps going, the Initial Spread Index combining wind wi

Assembles the current state of geomagnetic activity from four NOAA sources and says what each one is good for. The planetary Kp index is the standard scale and maps to the G-scale storm levels, but it is computed from ground magnetometers and therefore describes a storm that has already arrived. Rea

Estimates how likely satellite navigation is to be degraded, keeping two distinct mechanisms apart. Ionospheric delay error rises with geomagnetic activity, affects single-frequency receivers far more than dual-frequency ones, and shifts the computed position without any obvious sign that something

Collects the current observation, the terminal forecast, nearby pilot reports and active SIGMETs for the requested airports and returns them in one shape. The observation carries temperature, dewpoint, wind with gusts, visibility, altimeter setting, the cloud layers with their bases, and the derived

Combines the current wind at an airport with the bearings of its runways to give, per runway direction, the headwind or tailwind component and the crosswind component. Runway geometry comes from OpenStreetMap, where runways carry an explicit bearing or one derived from their designator, and both the

Takes a route as an ordered list of waypoints, samples it at a chosen spacing and tests every sample against the currently active SIGMETs carrying a volcanic ash hazard. For each hit you get the affected segment as a from-to pair of waypoints, the SIGMET issuing centre and flight information region,

Takes a scientific or vernacular name and returns the accepted taxon it belongs to, with the complete classification from kingdom down to species, the taxonomic authority, the GBIF key and any linked identifiers. The distinction the response keeps is the one that matters for anything downstream: whe

Retrieves occurrence records for a species within a radius of a coordinate and returns each with what makes it usable or not: the observation date, the coordinate uncertainty in metres, the basis of record — whether it is a preserved specimen, a human observation or a machine detection — the publish

Assesses the recorded biodiversity of an area around a point: how many distinct species appear, how many records support them, how recent those records are, how many separate datasets contributed, and the breakdown by kingdom. The trap this service is built around is that record density measures obs

Builds a monthly profile of when a species is recorded near a point, from historical occurrence data, and corrects it for observation effort. The correction is the substance of the service: raw monthly counts follow the observers, who are outdoors more in May than in November, so an uncorrected prof

Looks a marine organism up in the taxonomically curated register rather than in an aggregator, and returns the accepted name with its AphiaID, the authority, the rank, the full classification and the recorded status. Where the queried name is not the accepted one, the accepted name is given together

Assembles all names associated with one taxon into a graph with the accepted name at the centre and every synonym, basionym and alternate representation as a node carrying its status, authority and the register that supplied it. Two registers are queried rather than one because their disagreement is

Takes one or more district metered areas, each with a flow series and optionally a pressure series, a metered consumption figure and a service connection count, and returns three independent leak indicators per area plus a ranking across all of them. The first is minimum night flow: the lowest flow

Queries the Sensor.Community live area feed, keeps the newest noise reading per outdoor sensor within the requested radius, and returns nearest readings plus median, p10 and p90 LAeq. It never converts missing sensors into an estimated dB value. Community sensors are indicative rather than calibrate

Fetches two 128×128 NASA GIBS Harmonized Landsat Sentinel-2 reflectance renderings for a coordinate window, decodes the PNGs locally and compares only pixels present in both dates. It reports measured RGB change plus transparent colour-class heuristics for built-up, water/flooding and vegetation los
