Data Access Viewer (DAV) - Quick Start

The POWER Data Archive's solar and meteorological parameters can be accessed on the POWER web site via the Data Access Viewer (DAV). To request data using the DAV, follow the steps outlined in the video above and the list below.

Quick Start Steps

1) Choose a User Community: This will determine which units per parameter to return to the user for their selection.

2) Choose a Temporal Level: This will determine the temporal average of the datasets to be returned.

3) Enter Lat/Lon or Add a Point to Map: Users can enter global coordinates in decimal degrees or click a point on the map to retrieve coordinates at the map click location.

4) Select Time Extent: Users can select a Start and End time between 01/01/1981 – Near Real Time (NRT) to access data for selected parameters. Depending on the temporal level, you may need to provide YYYYMMDD or YYYY dates.

5) Select Parameters: Users can select up to 20 parameters.

6) OPTIONAL - Select Advanced Parameters: Adjusting these parameters may change the default values for retrieved data.

7) OPTIONAL - Select Output File Formats: Check the box if you wish to immediately download the results of your data request. Various files are available for download including GeoJSON, CSV, ASCII, NetCDF, etc.

8) Submit and Process: Once all data options have been made, the user can submit and retrieve the requested files. A line chart and histogram are also shown per parameter. Users can download the files and interact with the charts as necessary. You can also access a request URL from the output pane to customize for your applications.

The resulting page will provide time series plots of the selected data parameters. To download data in the previously selected format, click the appropriate box under the "Output Files". For a more detailed explanation of the steps, see the DAV User Guide.
