preMetabolizer - A Utility Package for the streamMetabolizer Package
Tools for preparing environmental time series before fitting stream metabolism models. The package includes helpers for downloading meteorological and elevation data, aligning irregular observations, converting units, and calculating light, pressure, dissolved gas, and water property inputs for streamMetabolizer.

flowcam - Download and Animate USGS Stream-Gage Camera Images
A tidy interface to the U.S. Geological Survey (USGS) National Imagery Management System (NIMS) API (<https://api.waterdata.usgs.gov/docs/nims/overview/>), which stores and serves images collected by stream-gage cameras at monitoring locations across the United States. Provides functions to discover cameras by NWIS site number or camera ID, list and filter available images by date and time, download images at multiple resolutions, and assemble downloaded frames into animated GIFs or MP4 videos. Integrates with the 'dataRetrieval' package (<https://doi-usgs.github.io/dataRetrieval/>) to enrich camera records with watershed metadata (drainage area, hydrologic unit code, state, county) and to retrieve co-located streamflow, stage, or water-quality time series — enabling direct comparison of visual stream conditions with measured observations. API authentication uses the 'API_USGS_PAT' environment variable shared with 'dataRetrieval', so a single key covers both packages.
