This dataset provides estimated Remote Sensing Streamflow (RSQ) data at selected river reaches in Alaska. Reach-specific relations between satellite-derived water-surface elevation data and dynamic surface water extent data were used with a modified form of the Manning's streamflow equation to estimate streamflows. The streamflow estimates were used to create rating tables that define the relation between discharge and satellite-observed water-surface elevation. The streamflow estimates in the gage_data.csv files are derived from these rating tables, interpolated using a polynomial regression equation. Data are organized in child items named for each river reach. Reach-specific details are provided in a README file contained in each child item as a Portable Document Format (PDF). A shapefile (all_sites.shp) is provided to show coordinate locations of the RSQ gage sites along with a comma separated value (CSV) formatted file (ALL_SITES_RSQ_GAGE_DATA.csv) containing all estimated records for the RSQ gage sites. A web map service of the RSQ gage site locations and attribute table is also available on this page.

This dataset provides computed remotely-sensed streamflows (RSQ) at river reaches of selected rivers in Alaska. We used the relation between water-surface elevation data derived from satellite altimetry and dynamic surface water extent data derived from LANDSAT and Sentinel imagery data with the Modified Optimized Manning Method Algorithm (MOMMA) to compute remotely sensed streamflows. Data are organized in ZIP packages named for each river reach. Reach-specific details are provided in a README file included in each river reach ZIP package. Depending on the input data available for specific reaches, we used different workflows to estimate river reach width and process the data from river reaches. Each workflow is detailed in its own metadata record (denoted in the filenames: HLS, SatTRAX, DSWE). The data filenames indicate which workflow was used and which metadata record is applicable. All three metadata records are provided for download in: "METADATA_DOWNLOAD.zip".

Relations between water-surface elevation data derived from satellite altimetry and dynamic surface water extent data derived from LANDSAT imagery data were used with a modified Manning's equation to compute remotely sensed streamflows (RSQ) at locations on the Tanana, Yukon, Susitna, Nushagak, Copper, Koyukuk and Knik Rivers in Alaska using satellite data. Data are organized into zip archives named for each study reach. Refer to the README file in each study reach archive for additional reach-specific details.
