ArcGIS Services¶
The RESTful ArcGIS Image Services and Feature Services support data distribution through a framework of temporal based endpoints. POWER Version 10 image and feature services refer to the Zarr-based analysis ready data in the AWS ARD bucket.
Types¶
These are the Temporal Image Services that return user community specific Analysis Ready Data (ARD) products.
| Services | Description |
|---|---|
| Monthly | Provides select parameters as summarized monthly values dating back to 1981 (for meteorology parameters), 1984 (for solar irradiance parameters), or 2001 depending on availability. |
| Annual | Provides select parameters as summarized annual values dating back to 1981 (for meteorology parameters), 1984 (for solar irradiance parameters), or 2001 depending on availability. |
| Climatology | Provides parameters as climatologies for a pre-defined period with monthly average, maximum, and/or minimum values available. |
Access Options¶
You can access ArcGIS items as image and feature service layers in NASA Earthdata GIS's Portal and within the POWER group of the NASA ArcGIS Online Organization.

Accessing in GIS Software¶
This tutorial guides you through how to access and visualize real-world climate data through ArcGIS Image Services in ArcGIS Pro and QGIS.
ArcGIS Pro¶
1) Open ArcGIS Pro and either create a new project or open an existing one.
2) In the Catalog pane, right-click on ‘Servers’ and select ‘Add ArcGIS Server.’ In the dialog box that appears, choose 'Use GIS Services' and enter the image service URL.
3) With a map open, navigate to the Map tab. In the Layer Group, click the ‘Add Data’ dropdown and select ‘From Path…’ In the dialog box that appears, enter the following path with the layer name such (e.g. POWER_ANNUAL_METEOROLOGY_LST): https://gis.earthdata.nasa.gov/image/rest/services/POWER/<service-name>/ImageServer
4) Click ‘Add,’ and the POWER image service will be added to the map as a layer. You will need to repeat this process for each POWER image service. For a complete list of available services, please visit the EGIS rest service page or the POWER documentation.
QGIS¶
1) Open QGIS and locate the Browser panel on the left. Right-click on ‘ArcGIS REST Servers’ and select ‘New Connection.’
2) In the dialog box, give your connection a name (e.g., “NASA POWER”) and enter the service URL: https://gis.earthdata.nasa.gov/image/rest/services/POWER/
3) Click 'OK', and the server will appear in your list. Expand it to view the available image services. You can double-click or drag any data set into your map canvas to begin working with it. This method allows you to visualize and analyze real NASA climate data.
