The daily outputs generated by this project are provided on a per-HUC12 datum. Presently, the various services only return the HUC12s for which DEP produces model results for. The resulting coverage of these HUC12s is not necessarily spatially complete within the domain of interest. For example, HUC12s that have no agriculture (ie urban areas) are not modeled.
The primary web-service endpoints emits GeoJSON and can be found here:
This service supports the following HTTP GET options.
|date=YYYY-mm-dd||Specify the calendar date you want data for. This date is presently valid for the US Central Time Zone.|
|date2=YYYY-mm-dd||Optional. If provided, this is a date inclusive range to provided summarized data for.|
|domain=XX||Optional. Provide the result for the given state only, if a HUC12 covers multiple states, they are included as well.|
|callback=myfunc||Optional. If provided, wraps the result in a JSON-P style response.|
Here are some examples for the service above:
- Return all HUC12 results for 5 June 2016
- Return just Minnesota data for 5 June 2016
- Return Kansas totals for all of 2016
The GeoJSON response provides the following attributes
|avg_loss||Average sheet and rill soil detachment. This is not necessarily soil delivered to the bottom of the modeled hillslope. [tons per acre]|
|avg_delivery||Average sheet and rill soil delivery to the bottom of the hillslope. [tons per acre]|
|qc_precip||HUC12 averaged precipitation for the CST/CDT local day. [inches]|
|avg_runoff||HUC12 averaged runoff. The depth of water delivered to the bottom of the modeled hillslope. [inches]|
