Summary
This child data release includes RGB (red-green-blue) videos acquired from an Unmanned Aircraft System (UAS) during a tracer experiment performed on the Missouri River near Columbia, Missouri, on May 5, 2021. One of the primary goals of this tracer experiment was to assess the feasibility of inferring concentrations of a visible dye (Rhodamine WT) from various types of remotely sensed data in a large, highly turbid natural river channel. Previous research on remote sensing of tracer dye concentrations has focused on clear-flowing streams, but the Missouri River is much more turbid. As a result, the effect of the dye on the reflectance of the water could be obscured by the effects of suspended sediment on reflectance. This experiment [...]
Summary
This child data release includes RGB (red-green-blue) videos acquired from an Unmanned Aircraft System (UAS) during a tracer experiment performed on the Missouri River near Columbia, Missouri, on May 5, 2021. One of the primary goals of this tracer experiment was to assess the feasibility of inferring concentrations of a visible dye (Rhodamine WT) from various types of remotely sensed data in a large, highly turbid natural river channel. Previous research on remote sensing of tracer dye concentrations has focused on clear-flowing streams, but the Missouri River is much more turbid. As a result, the effect of the dye on the reflectance of the water could be obscured by the effects of suspended sediment on reflectance. This experiment thus provided an initial test of the potential to map dye concentrations from remotely sensed data in more turbid rivers like the Missouri.
The experiment involved introducing a pulse of Rhodamine WT dye into the channel at an upstream transect and then observing the dispersion of the dye along the river using various types of remotely sensed data as well as in situ measurements of dye concentration. We sought to develop quantitative approaches for inferring infer dye concentrations from the remotely sensed data, including videos obtained via UAS. These videos were acquired using the built-in Sony camera module onboard a pair of Parrot ANAFI UAS in a 4K Cinema mode with 4096 X 2160 pixels and a native frame rate of 24 frames per second. Acquiring videos from two separate ANAFIs taking turns hovering in a fixed position above the channel provided continuous coverage in time; a series of five videos, each with a duration of approximately five minutes, captured the passage of the dye plume. The time stamps associated with each video were used to link the remotely sensed data to concentration measurements made in situ during the experiment, but the videos were not geo-referenced.
The videos available in this data release are listed in the file MissouriRiverDyeVideos.csv, which specifies the video file name and the start and end time of each video in the local time zone (Central Standard Time). Each video is provided as an *.mp4 format file.
