Bay-Delta SCHISM Atmospheric Collection v2.0
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.

NARR precipitation and radiation 2000-2022 NARR precipitation and radiation data 2000-2022. Used alongside baydelta_sflux. Don't use NARR for wind, the resolution isn't fine enough and high wind locations will be missed. | Download | TAR.GZ | 04/22/25 |
baydelta_sflux_2004_2022.tar.gz Interpolated wind, humidity, pressure, etc as expected in the "air" netCDF input for SCHISM. Covers to Sep 2022. Usually accompanied by NARR for radiation and precipitation. For runs after 2020, see the HRRR datasets which are used for air, precipitation and radiation. | Download | TAR.GZ | 04/28/25 |
