Access high-resolution atmospheric model data and rendered map tiles via OGC standards.

This endpoint exposes two service modes selected by the SERVICE query parameter:

SERVICE=WCS (default), OGC Web Coverage Service 2.0.1. Numeric data extracts from forecast and analysis grids, listed by coverage ID below.
SERVICE=WMS: OGC Web Map Service 1.1.0. Rendered PNG map tiles of aviation weather variables.

Authentication is required for all requests.

Web Coverage Service (WCS)

Request Types

`REQUEST`	Purpose
`GetCapabilities`	Capabilities document listing all available coverages
`DescribeCoverage`	Detailed metadata for a specific `CoverageId`
`GetCoverage`	Data or imagery for the specified parameters

Parameters

Core Parameters

Parameter	Required	Default	Description
`SERVICE`	No	`WCS`	Service type, `WCS`
`REQUEST`	No	`GetCoverage`	Operation type (see above)
`VERSION`	No	`2.0.1`	WCS protocol version
`CoverageId`	Yes*	-	Coverage identifier (see "Available Coverages" below)
`RANGESUBSET`	Yes*	-	Variable name (e.g. `wind_speed`)
`FORMAT`	Yes*	-	Response format (see "FORMAT Options" below)
`CRS`	No	`CRS:84`	Coordinate reference system (WGS 84 lon/lat by default)

*Required for GetCoverage requests only.

SUBSET Axes

Spatial and temporal filtering using OGC axis syntax. Repeat the SUBSET key for each axis.

Value syntax	Example	Description
`lat(value)`	`SUBSET=lat(40)`	Latitude in decimal degrees
`long(value)`	`SUBSET=long(-98)`	Longitude in decimal degrees
`z(value)`	`SUBSET=z(2)`	Exact height in metres AGL. Omit for most requests, the service selects the correct level per variable (e.g. temperature → 2 m AGL, wind_speed → 10 m AGL). Use only when targeting a specific non-default level. `z(0)` is not a valid level for most HRRR/GFS variables and will return 400. Not valid for RTMA or NDFD.
`f(duration)`	`SUBSET=f(PT1H)`	Forecast offset as ISO 8601 duration. Required for HRRR/GFS. Not valid for RTMA (analysis, no forecast axis).

Forecast coverages (HRRR/GFS): &SUBSET=lat(40)&SUBSET=long(-98)&SUBSET=f(PT1H) Analysis coverages (RTMA/NDFD): &SUBSET=lat(40)&SUBSET=long(-98)

WCS returns JSON data only, pass FORMAT=JSON (uppercase literal). Image formats are not supported by WCS and will return a 400 error. WMS map tiles (rendered PNG images) are requested separately using SERVICE=WMS: see the WMS section below.

FORMAT value	Description
`JSON`	Numeric variable values as a JSON object

Web Map Service (WMS), Aviation Weather Global Forecast Maps

Rendered PNG map tiles via OGC WMS 1.1.0. Use SERVICE=WMS (or SERVICE=WMTS) and REQUEST=GetMap.

Global coverage at ~1 km native resolution. Most layers provide a 24-hour forecast horizon and refresh every 15 minutes; severe-weather and now-cast layers (thunderstorm, flight_rules, precipitation_arrival, lowest_cloud_top_altitude) are limited to a 5-hour horizon and can refresh as often as every 5 minutes. Tile datetimes are rounded to 10-minute increments.

Layer Naming Convention

meandair-global-none-{variable}-{bit_depth}-epsg_{crs_code}

Where {crs_code} is 3857 (Web Mercator) or 4326 (WGS 84). Most variables use {bit_depth}=16; icing_severity and weather use {bit_depth}=8. Use REQUEST=GetCapabilities to confirm the exact bit-depth identifiers exposed for each variable.

WMS only. Bounding box of the map tile in the chosen SRS, formatted as minX,minY,maxX,maxY.

CRS?string

Coordinate reference system. Default is CRS:84 (WGS 84 lon/lat).

Default"CRS:84"

CoverageId?string

Coverage identifier. See endpoint description for the full list of available coverages (HRRR, GFS, RTMA, MRMS, NDFD). Required for GetCoverage and DescribeCoverage.

DIM_FORECAST?string

FORMAT?string

WCS only. Response format. Must be JSON (uppercase literal). WCS returns numeric JSON data only, image formats are not supported by WCS and will return 400. WMS map tiles use FORMAT=image/png but that is a WMS-specific parameter.

WMS only. Height of the returned map image in pixels.

LAYERS?string

WMS only. Aviation weather layer name following the pattern meandair-global-none-{variable}-{bit_depth}-{crs} where {crs} is 3857 (Web Mercator) or 4326 (WGS 84). Use SERVICE=WMS&REQUEST=GetCapabilities to retrieve the full list of available layer names.

Example (forecast): &SUBSET=lat(40)&SUBSET=long(-98)&SUBSET=f(PT1H). Omit z for surface requests, the service selects the correct AGL level per variable.
