Bay-Delta SCHISM Atmospheric Collection v2.0

Published by California Department of Water Resources | State of California | Catalog Last Checked: July 28, 2025 at 07:34 PM | Dataset Last Updated: April 27, 2025 at 04:33 AM
This dataset collects together collated and interpolated data required to run schism and are formatted for use in the model. SCHISM requires atmopheric data files in netcdf format as described here: http://ccrm.vims.edu/w/index.php/Atmospheric_forcing. These include ordered files with _air (wind, spec. humidity, pressure etc) _rad (long and short wave radiatin) and _prec (precipitation) in the name. These are often implemented using symbolic links to the files here. The data used for Bay-Delta SCHISM vary by period. For simulations centered before 2020, we use the _air data constructed by DWR based on spatial interpolation from approximately 71 public and private stations around the Bay-Delta. The _prec and _rad data are obtained from North America Regional Reanalysis data: https://psl.noaa.gov/data/gridded/data.narr.html. For simulations centered after 2020, we use the High Resolution Rapid Refresh (https://rapidrefresh.noaa.gov/hrrr/) data for all three variables. Around 2020 both options are viable and we choose whichever provides continuity across the period of study.
