Data Availability Statement
Datasets generated by the SFA and collaborators at the ER are publicly available in online repositories, including ESS-DIVE, NCBI, United States Geological Survey (USGS), NASA DAAC: National Snow and Ice Data Center, Figshare, and HydroShare (as listed in Table S1 of the Supplementary Information). The SFA alone has 43 public datasets with associated metadata available on ESS-DIVE that include many of the long-term monitoring and spatially-extensive remote sensing and associated ground campaign datasets. A majority of the ER data collection can be accessed on ESS-DIVE through the East River watershed portal (https://data.ess-dive.lbl.gov/portals/east-river-watershed). Users must be logged into ESS-DIVE with their ORCiD credentials to download the public data packages. Large datasets such as the remote sensing or model products are stored and distributed through public data transfer nodes on the DOE’s National Energy Scientific Computing Center (NERSC).
The SFA has an open data policy where project-generated data are made publicly available following the U.S. Department of Energy’s guidelines (https://watershed.lbl.gov/data/data-policy/). The data are typically licensed under Creative Commons by Attribution (CC-By4.0) or Creative Commons Public Domain (CC0) usage policies. The usage license, measurement uncertainties, quality checking process, and dataset metadata are specific to each dataset and should be obtained directly from the published data in the listed repositories.
Table 1 . ER Data types, variables, and methods of data generation. Methods and instruments used, and uncertainties (if available) are described in the published datasets on the repositories. Several time series measurements are ongoing; see Varadharajan et al. (2020) for location and instrumentation metadata associated with these measurements. Table S1 has the full list of 72 East River datasets spread across different repositories; some datasets are listed under multiple data types.
