This data is in support of the publication in review "Using sensor data to dynamically map large-scale models to site-scale forecasts: A case study using the National Water Model". It is all the raw data extracted from the NWM flow forecasts for Iowa and the IFIS stage readings.
For the NWM data, each date has it's own tab-delimited file with columns being the time (hrs) and rows being the NHD site.
For the IFIS gages, each tab delimited file is for a single site for the period of record.
