Section 3 Data Sources

3.1 Covariate Datasets

3.1.1 Catchment Delineation

The stream temperature model uses the National Hydrography Dataset High Resolution Delineation Version 2 (NHDHRDV2) catchment delineation.

Shapefiles of the catchments can be downloaded from: http://ecosheds.org/assets/nhdhrd/v2/

The spatial_XX.zip files contain pre-staged datasets for each HUC2 region (e.g. spatial_01.zip contains the catchments for the HUC2 region 01).

3.1.2 Climate Data

Daily air temperature and precipitation were obtained from the Daymet V3 gridded estimates of daily weather parameters for North America. The raw Daymet datasets (NetCDF4 files) were processed using the code in walkerjeffd/sheds-daymet.

3.1.3 Geospatial Characteristics

Geospatial characteristics of each catchment were generated using the code in basinCharacteristics. More information can be found on the SHEDS GIS Data page.

3.2 Stream Temperature Observations

Temperature observations extractd from the SHEDS Stream Temperature Database, which contains data uploaded from numerous state and federal agencies, universities, and non-profit organizations.
